• Windows Home Server installation fails because it can't find the DVD drive anymore

  - by BBlake

  I've got an old Dell Dimension 8300 desktop I decided to convert into a WHS box. I popped in a pair of 1 TB SATA drives, which were recognized fine by the BIOS and the currently installed OS (XP), so I decided to go ahead and install WHS. Near the end of the installation, WHS acts like it can no longer find the DVD drives (either of them, the box has a DVDROM and a DVDRW). The specific error is gives is the "Can't configure storage" error. I've found several forums where people say they get this error if they remove the boot DVD during the installation (at the time of the first reboot). However, I never removed the DVD. After the error, if fails into WHS, so it did mostly install and I can work with WHS. However, it refuses to recognize the network card, video card and while it shows the two DVD drives, any CD/DVD I insert in either drive the system says is corrupted and unreadable, even though none of them are. I've tried several reinstalls both removing and not removing the DVD, but the result is the same regardless. Any other tricks anyone found? If I can't figure this out, maybe I'll just install SBS2008 and fake it up to be similar to WHS with some addin tools. Shouldn't be too hard to create something since WHS is based on SBS2003 anyway.

• Does AMD Cool n Quiet Slow Down Your System?

  - by Software Monkey

  I discovered today that having AMD Cool n Quiet enabled in my BIOS appears to be slowing down my Windows XP SP2 system by about 29% on memory & CPU intensive workloads. I was wondering if (a) anyone else had encountered this, (b) anyone can offer an explanation, (c) there are any negatives I need to be aware of if I keep AMD CnQ disabled. With some superficial testing so far, I don't immediately notice any difference with CnQ off (other than the performance being what I expected from this new hardware). It seems to ramp up the CPU fan a little bit as my program maxes out 1 core, but that's the same as with CnQ on. And when I let the system idle the CPU fan slows down and the systems as quiet as a mouse (after years of 6 small fans churning like they want to go into orbit it's nice to again have a system where I can hear the HDDs seeking). Bonus question: Does CnQ cause issues with system stability? I ask because the reason I disabled it was because I have had a few freezes and 1 spontaneous reboot with my new hardware.

• Windows XP corrupts registry every several hours

  - by Ilya Kazakevich

  There is a Dell XPS 400 with Windows Media Center installer. It is installed on RAID (Intel Matrix Storage) which is built-in chipset south bridge. Raid has two 150 Gb WDC drivers connected as mirror. All drivers and updates are installed( sp3 and so on). A week ago PC changed its video mode to 256 colors (like VESA mode) and after several moments I got BSOD: c000021a: 0xc0000005 Doctor watson did not create dump although it is installed as default debugger. After reboot it said that config file is missing or corrupted. So, I boot to recovery console and found that registry file (config) is so small. I've replaced it with one from recovery point and windows booted sucessfully. But after about 3 hrs -- it has crashed again in the same wat! I look in event viewer: is said that Explorer.exe failed to open \global??\DLIAFS. I look in winobj, and found that it is a device. I made "deny from everyone" for this device ACL, and after several hours my windows crashed. I restored registry, boot again and there was no error about DLIAFS. I did full chkdsk and it did not found anything bad. But I found event about error paging to \Harddrive1\D. I do not have pagefile there, but I thought I should check my disk again. Unfortunatelly I cannt use smart tools for RAID, but I downloaded latest software from Intel (it can do the same things like RAID bios can but from windows). It verified my disks, found some errors, fix them, than I rebooted. And it crashed again. I am lost. What (except kernel debugging) could be done here? Thanks

• No LPT port in Windows 7 virtual machines

  - by KeyboardMonkey

  Windows 7 has MS virtual PC integrated, the VM settings don't give a parallel LPT port mapping to the physical machine. Where did it go? Has anyone else noticed this, and found a solution? Update: After much digging, I found the one and only reference to this issue, on the VPC Blog: "Parallel port devices are not supported, as they are relatively rare today." -More details- It's a XP VM I've been using since VPC 2007 days, which did have this functionality. This is to configure barcode printers via the LPT port. Since the (new) MS VM can't map to my physical LPT port, I'm having a hard time configuring printers. My physical ports are enabled in the BIOS. It has worked the past 3 years, before switching to Win 7. Any help is appreciated. This screen shot of the VM settings shows COM ports, but LPT is no more In contrast, here is a screen shot of VPC 2007 (before it got integrated into Win 7). Notice how it has LPT support

• PC won't boot after hanging during Windows 8 automatic repair [closed]

  - by Mun

  I've got a custom built PC using an ASUS P5E motherboard and Intel Q6600 CPU. I plugged in my mp3 player to the USB port yesteday, and when I came back to the machine after about an hour or so, the Windows 8 automatic repair message was on the screen. It seemed to stick there for an hour, after which I decided to just hit reset and try and figure out what was going on. However, the machine rebooted to a black screen before even getting to the BIOS, with the monitor lights just blinking indicating there was no signal. Tried powering down completely, waiting a few minutes and then powering back up again with no difference; black screen with monitor lights blinking. Tried leaving it on for a while and then pinging from another machine or accessing it via something like LogMeIn, but everything showed the machine as being offline. There were also no error beeps or anything like that. Also tried unplugging all of the memory and rebooting and that also caused no error beeps. Removed one of the display cards and left the other one in there, and still only a black screen. I'm inclined to think that the motherboard or CPU is fried, but there is no indication of damage on any components and the CPU fan seems to be working fine as it always has, so overheating seems unlikely. It's also plugged into a surge protector. The motherboard also has a green light which still lights up. As everything was still working fine before hitting the reset button during Windows 8 automatic repair screen, at which point everything stopped working, it seems unlikely that this problem is down to component failure. Has anyone else experienced anything like this or have any ideas on what could be causing this behavior?

• How can I connect integrated webcam with virtualbox

  - by Mike Stumpf

  I am trying to use a Windows XP VM for VirtualBox on my Windows 8.1 laptop. I have tried the usual attaching USB device but I get an error saying "USB device is busy with previous request". My webcam is not active in any applications and this happens after a clean reboot of the host, the guest, and VirtualBox.

• Access Windows Boot Manager selector when timeout is set to 0?

  - by Kyle Cronin

  I've installed Wubi onto a Windows Vista computer. I've also set the boot timeout to 0: bcdedit /timeout 0 However, now I can't figure out how to get the menu to come up at all! I read on the internets that I had to hold F8 or space when starting up, but they doesn't seem to do anything. Is there a different key or setting I've overlooked? The computer itself is a Dell that's a few months old. The keyboard is USB, but I don't think that's the problem as I can get into the BIOS just fine. Maybe I'm doing it wrong? Am I supposed to hold the keys or rapidly tap them (I've tried both)? If it helps, here's the output from bcdedit: C:\Windows\system32>bcdedit Windows Boot Manager -------------------- identifier {bootmgr} device partition=C: description Windows Boot Manager locale en-US inherit {globalsettings} default {current} resumeobject {5460d9d2-d391-11dc-9d9f-aba67a8797c5} displayorder {current} {e2484fe7-5e97-11de-84d4-0024e8074422} toolsdisplayorder {memdiag} timeout 0 resume No Windows Boot Loader ------------------- identifier {current} device partition=C: path \Windows\system32\winload.exe description Windows Vista locale en-US inherit {bootloadersettings} recoverysequence {572bcd55-ffa7-11d9-aae0-0007e994107d} recoveryenabled Yes osdevice partition=C: systemroot \Windows resumeobject {5460d9d2-d391-11dc-9d9f-aba67a8797c5} nx OptIn Real-mode Boot Sector --------------------- identifier {e2484fe7-5e97-11de-84d4-0024e8074422} device partition=C: path \ubuntu\winboot\wubildr.mbr description Ubuntu

• 2008 Sever Randomly reboots.

  - by Jeff

  I'm out of ideas here. We have a 2008 Server that keeps rebooting 2-3 times a day at completely random times with an "Unexpected Shutdown" event. There are no Dumps, no events leading to it just like it loses power then comes back online. I ran a Diagnostic of the power supply and it has had continuous power for months. In addition, the temperature of the processors are maxing out at 40 degrees Celsius. Anyone have any ideas how to figure out why this is restarting all the time? This is a DMZed Web server so it doesn't do too much process wise.

• NVidia Graphic Card troubleshooting

  - by Berry Langerak

  My dad has a HP pavilion laptop, which is over 6 years old. It contains an onboard graphic card, a NVidia GeForce 8400M GS. Since a week or two, he's getting BSOD in Windows Vista. Also, the screen was acting up; strange lines and figures keep creeping up, but only once in a while -- not always. Thinking that it might be the drivers he had recently upgraded, I decided to downgrade the driver, with no luck at all. I then continued to deinstall the driver, and reinstalling the current stable version, but alas, to no prevail. Windows kept crashing during the course of the last two weeks, and thinking it might be Windows breaking up, I decided to upgrade his Vista installation to Windows 7, as I've been hearing good things about it. Alas, even that didn't help, and it seems the strange lines and figures keep popping up. I've opened the laptop itself, thinking it might simply be overheating because of clogging in the vents, but that's not the case, it's clean as a whistle. Now for the actual question; does anyone have a decent flowchart on how to troubleshoot such issues? It might well be the videocard itself, as the strange lines and figures sometimes even appear during BIOS and POST, but I'm not sure.

• Can I have damaged a CPU ?

  - by Pascal

  Hey guys, This is a question I asked on Anantech forums, but I just discovered this community and think this question would fit right in. Here goes: I built a PC around a Q9550 1 1/2 years ago (MoBo is an Asus P5Q deluxe). Specs give 2.83GHz, OC'ed it to 3.40 GHZ without any problem (or so I thought) till 2 months ago. Cooling is provided by stock Intel Fan... 2 Months ago, I began to see random crashes, bios saying CPU overheat error... PC would reboot at OC'ed speed without any problem. Since last saturday and a few more crashes, PC won't reboot at 3.40 GHz, and even at stock speed (2.83 GHz), I got core temperatures of (60 C idle, 95 C under load) on the first two cores. This is the 4 core temperatures I am talking about, not the T-CPU which obvioulsy is lower. Fan is running at a steady 2000 RPM. Questions for you : 1. Is 2000 RPM the normal speed of the Intel fan or is my fan somehow broken (which could explain the overheating). In this case, any recommendation for a good fan for OCing ? 2. Hypothesis I fear is the right one: can the CPU have been slowly damaged over time by this OCing, meaning there is nothing much to do except waiting for it to die ? (As a side note, I am surprised that the 9550 is still around 300 $CDN here... Thought it would have been cheaper with all those i3/i5/i7 around). Any help or advice would be more than welcome...

• Why Virtual Box won't give me option to create 64 bits guests?

  - by Eduardo Born

  My host is x64 bits Windows 8.1. I downloaded the latest Virtual Box (4.3) and I'm trying to create a VM with a 64 bits Ubuntu OS (ubuntu-12.04.3-desktop-amd64). When I go to New VM wizard, it doesn't give me option to select "Ubuntu (x64)" as I have seen in other people's screenshots, only just "Ubuntu". As a result, the ISO can't boot. I tried in another PC and Virtual Box gives the x64 variants to most listed OS... Control Panel shows x64 OS, x64 processor. My host laptop is a Sony Vaio VPCZ22UGX/N, Intel® Core™ i7-2640M processor. CPUz shows Vx-t is available on my processor, of course. Here is what I tried so far: I enabled IO APIC as required in the docs. I have virtualization enabled in the BIOS. It works fine in VMware. Check that Hyper-V is not running or even installed on my Windows. Same for VMware. I also tried running the command: VBoxManage modifyvm [vmname] --longmode on for that VM, but no change.. I think the issue is really that I can't select x64 variant of the Ubuntu OS for that VM. Other people seem to indicate that's a requirement, but I don't get that option for some reason. I spent a lot of time and can't find what's wrong... Anyone knows what could be missing here? Thank you very much!! Eduardo

• How to run the CPU at something like 75%?

  - by Tobias Kienzler

  My notebook is too old for me to invest into a new fan (it will simply be replaced by a new one when the final heat death occurs), but when it runs on full speed I feel like sitting in front of a vacuum cleaner with integrated cooking... I'm currently using NHC, the Max Battery mode of which let's the CPU run at 50% (~800 MHz). That's fine for most applications, and both temperature and noise remain low. However, on some occasions I need a bit more speed, more around 75% maybe. Can I set the power saving settings somehow so that the CPU won't surpass 75% of it's capability so that an acceptable compromise between power and noise is achieved? I can't set the CPU frequency in the BIOS and since on rare occasions I'd like to be able to switch to 100% without much hassling, hardware solutions like setting jumpers are no option. This answer to a similar (linux!) question mentions NHC should be able to offer these options, but for me they are all greyed out: The notebook is an Asus Z9200K, I guess NHC doesn't support its chipset enough for these advanced options.

• Formatted C: from Windows 7 setup, now it won't even install

  - by ocurro

  Help, I'm so confused. I did more or less what's been described here: I formatted Vista and installed Windows 7 over it. Problem is that I'm now unable to boot (...) [1] I'm installing Seven on top of Vista on ACER AS1410 Notebook When it comes to the part where I choose where to install, I pick the partition labeled C: but instead of keeping windows.old files (what would I want them for?) I choose to go and carelessly format the partition (my bad). It shows me this error: Setup was unable to create a new system partition or locate an existing system partition. See the Setup log files for more information Now the only option is "Load Driver". i have tried installing every single one from ACER website, none of them are useful. I even flashed orig. BIOS. I've tried going back and choose "Repair" like in the picture:[2] but I only get an error: "Failed to save startup options" I think this is weird, what else can I do?

• Can grub and BCD work simultaneously?

  - by wuputah

  Here's my setup. After I installed a new SSD, I have: Original Windows 7 on sdc1 (to be retired) Copy of Windows 7 on sdb2 A Windows system partition on sdb1 Ubuntu 12.04 on sda, /boot and ergo grub is on sda1 Grub is MBR on sda and set to boot from BIOS. I prefer to not change this; grub is much preferable as a boot manager. I've run update-grub from Ubuntu and grub seems to be correctly configured as all options are available: I can boot any of the 3 Windows partitions and Ubuntu. I also ran the repair tool to get Windows to add both installations to BCD. At present, choosing particular options seem to have no effect; the old version of Windows on sdc1 always boots. I don't understand what is causing this, but I can't figure out what. How does grub and BCD play along? I can't find any docs on this. My thought was to only boot Windows off sdb1, and then let BCD do the rest (present a menu to boot between sdb2 and sdc1, but I can't seem to get BCD to boot sdb2), but this has been unsuccessful. My configuration files: BCDEdit output grub.cfg

• Philips Monitor problems - vertical lines on screen

  - by asdasd

  I have an old CRT Philips Monitor 17'' and it was working well. There were problems with the electrical power and the monitor started to make some sound and a smoke was getting out of it. I quickly switched it off the power, and in the morning when the power was ok i started the monitor and it appeared to be working and it worked for a couple of minutes when i find out some smell was coming from it, and after 5 minutes the screen i was working shut down and on the monitor some vertical lines appeared - and nothing else. I thought it was the OS, so i rebooted the pc and while it was booting i realized the monitor didn't show the bios info etc, but the same vertical lines on the whole screen were on it, sometimes their color was changing and they were blinking, but no screen appeared - only those vertical lines. After a day, the monitor was ok again - i turned it on and no there were no lines, everything was working fine. The same for the next 2 days. My question is: If anyone had ever had the same problem, can you help me ? THe monitor may be ok now but i am afraid it can get back those lines again. I don't know what to do, if you know please tell me whether should i take it to the service or not. Thank you.

• Wireless disconnects at random after upgrade to Ubuntu 10.4

  - by Daniel Elessedil Kjeserud

  After upgrading my home server from Ubuntu 8.10 to 10.4 my wireless seemingly drops out, even though my IRC client keeps it's connection to the servers, so it looks like the machine just stops taking wireless requests. A ping will give a me this Request timeout for icmp_seq 27 ping: sendto: Host is down After a while the machine just starts responding again, without any interaction from me.

• Reducing video mode switching during Linux boot

  - by Zack

  When I boot up my desktop computer, which only has Linux on it, the video mode and/or console font gets switched four times: When GRUB starts, it switches from 80x25 text to a graphical mode so it can draw a pretty background behind its menu; GRUB then goes back to 80x25 text after I pick something from the menu; When the KMS driver for my video card loads, it switches to a much higher-resolution text mode (I don't know if this is a hardware text mode or not); Finally X starts and it goes graphics and stays that way. I think this last switch does not change the resolution of the video mode, only the graphicalness. I'd like to get rid of as many of these mode switches as possible. Ideally, when GRUB takes over from the BIOS it would go directly to the same high-resolution text mode that the KMS driver selects, and the display would stay in that mode till X starts and brings up graphics. I am under the impression that this is possible by mucking with the kernel command line and/or the GRUB console module load parameters, but I don't know the details. GRUB 1.98+20100706, kernel 2.6.32.15 using Nouveau video drivers. Distro is Debian unstable. Please no answers that involve recompiling anything or cobbling together bleeding-edge kernel/driver combinations, I don't care enough about this to go to that much trouble. EDIT: Tobu suggests setting GRUB_GFXMODE to the full pixel resolution of the monitor, and GRUB_GFXPAYLOAD_LINUX=keep to avoid the mode switch after the menu goes away. This does part of what I want, but winds up being worse overall. There's no mode switch after the menu, but there's still a painfully-slow screen repaint (I should probably just give up on GRUB's gfxmode, it's waaaay too slow at 1920x1200). More seriously, there's now a double mode switch when nouveaufb loads, along with fun-looking error messages in dmesg [ 5.923798] [drm] nouveau 0000:02:00.0: allocated 1920x1200 fb: 0x40250000, bo ffff8801ba5f4600 [ 5.923802] fb: conflicting fb hw usage nouveaufb vs EFI VGA - removing generic driver [ 5.923821] [drm] nouveau 0000:02:00.0: PFIFO_INTR 0x00000010 - Ch 1 ("PFIFO_INTR" message repeats 400+ times) [ 5.925609] Console: switching to colour dummy device 80x25 [ 5.925802] Console: switching to colour frame buffer device 240x75

• SATA Windows 7 Problems

  - by Isaacs

  Scenario: Core 2 Duo processor, Gigabyte MB, 4 SATA Western digital 500 GB hard drives, windows 7 64 bit. Problem: Copying data from USB or among SATA hard drives is faulty. When trying to copy 20GB from one HD to another it starts off with normal ~14-15 MB/s transfer rates and eventually bogs down to < 120KB/s transfer rates. If I leave it alone over night I come back with my computer crashed and setting at BIOS detecting hard drives. Troubleshooting: Removed all but 1 HD with OS on it, everything seems to be happy. I can copy large files from USB HD to main/single HD. Ran SpinRite on all hard drives, no errors found. Tried adding one HD to machine and problem exists, tried switching SATA cables, and SATA ports on MB. Reinstalled windows 7 x2 (from different disks..). Oddly enough if I boot to a ubuntu everything works fine. Getting ready to purchase a new MB, but wanted to see if anyone had suggestions. Thanks!

• System freezes during boot process

  - by slugster

  Hi everyone, i have a machine running Win7 Ultimate. It was running fine, then it just froze - all the stuff i was doing was still on the screen, but mouse and keyboard input was ignored, any animation that was happening on the screen stopped, the machine literally just froze. So i rebooted (power off button), from then on the machine will reboot, but it ultimately freezes again. The instance when this happens will vary - i have made it as far as the Windows login screen, but mostly it will do the POST, then give me the option to press F1 to continue or Del to enter BIOS settings (but of course pressing a key has no effect - it's frozen!). I have disconnected everything not necessary for the boot process, the only peripheral that remains attached is the keyboard. (even the network cable is disconnected). Prior to this the machine was operating fine. The install of Win7 is only 2 days old, and it was a fresh reinstall (i.e. not an upgrade or repair). Can anyone give me an indication of what may be wrong here? I'm not sure if this question should be here or on SuperUser, please migrate it if i have chosen the wrong board.

It was running fine, then it just froze - all the stuff i was doing was still on the screen, but mouse and keyboard input was ignored, any animation that was happening on the screen stopped, the machine literally just froze. So i rebooted (power off button), from then on the machine will reboot, but it ultimately freezes again. The instance when this happens will vary - i have made it as far as the Windows login screen, but mostly it will do the POST, then give me the option to press F1 to continue or Del to enter BIOS settings (but of course pressing a key has no effect - it's frozen!). I have disconnected everything not necessary for the boot process, the only peripheral that remains attached is the keyboard. (even the network cable is disconnected). Prior to this the machine was operating fine. The install of Win7 is only 2 days old, and it was a fresh reinstall (i.e. not an upgrade or repair). Can anyone give me an indication of what may be wrong here? I'm not sure if this question should be here or on SuperUser, please migrate it if i have chosen the wrong board.

• Constant crashes in windows 7 64bit when playing games

  - by yx

  I've tried everything I can possibly think of in trying to fix this problem and I'm totally out of ideas, so any help would be appreciated: The problem: whenever I fire up a game, it works for a short while with no problems and then it would crash. Either its a hard crash, forcing me to reboot, or windows would report that the display driver has stopped working and recovered. Here is a list of things I've already tried: Drivers - tried the latest drivers (catalyst 9.12) as well as the stock drivers that came with the video card. Also have the latest BIOS/chipset Memtest - Ran Memtest86+ overnight, had no problems, the windows diagnostic tool also does not find any problems. Overheating - Video card/cpu temperatures are well below peak (42 and 31 Celsius receptively) PSU Voltage - CPUID shows that the voltage levels are all above what they should be. The PSU itself is only roughly 16 months old and is a good model. HDD - No errors when checked GPU - Brand new (replaced previous card since I thought it was the problem, apparently not) Overclocking - Everything is at stock levels, memory voltage is set to manufacturer's standard Specs: Motherboard: ASUS P5Q Pro CPU: Core 2 Duo E8400 3.0 ghz OS: Windows 7 home premium 64 bit Memory: Mushkin Enhanced 4GB DDR2 GPU: Sapphire HD 5850 1GB PSU: SeaSonic M12 600W ATX12V DirectX: DX11 Event Viewer after a crash always has these logged: A fatal hardware error has occurred. Reported by component: Processor Core Error Source: Machine Check Exception Error Type: Bus/Interconnect Error Processor ID: 1 The details view of this entry contains further information. A fatal hardware error has occurred. Reported by component: Processor Core Error Source: Machine Check Exception Error Type: Bus/Interconnect Error Processor ID: 0 The details view of this entry contains further information. A previous card that I had (4850x2) also had these errors, so I changed video cards, but the same thing is happening.

• Computer resetting semi-randomly

  - by Peter

  Hi, I'm having a problem with my desktop whereby it sometimes resets itself semi-randomly. For example, I'll switch it on, it'll boot an OS and shortly after getting to the desktop it will immediately reset with no warning. The time isn't consistent - sometimes it does it before reaching login. I'm pretty sure it's not an OS thing; have tried Ubuntu and a Windows install and both exhibit it. It also doesn't appear to be heat-related because sometimes it appears to be able to "get past" it and will then run stably even under load; if anything it seems to be worse from a cold start. My gut feeling is some kind of power issue but I'm clutching at straws a little. Any suggestions on how I could go about testing it or trying to narrow the problem down would be appreciated. The machine is four years old now so while I can replace components if needed, it's not worth enough that I'm comfortable buying new parts without being pretty confident that they'll fix the problem. Thanks in advance for any help :) Edit: Okay, the motherboard is a MSI K8N SLI; CPU is an Athlon64 X2 4200+. Has one video card, a GeForce 7800GT. 1GB RAM, not sure of brand; 3 hard drives, two SATA and one PATA. Flashed motherboard to latest BIOS some time ago. Edit the Second: I thought I'd narrowed it down to the PSU for a while, but then it recurred again. I ended up pulling everything out but CPU, RAM and motherboard and it still seems to be stuffed (if anything, it's gotten worse in the last couple of days). I assume it's one of those three components, but the machine is old enough that I don't really want to spend money replacing any of them. So thanks for everyone's suggestions; much appreciated!

• ESXi Guests will not boot on IBM x3550 M3

  - by Adrian

  I have a problem with Guests not booting under VMWare ESXi 5.0 on my IBM x3550M3 server. VM Host Server: IBM x3550 M3 7944AC1 server w/ 2x Intel Xeon E5607 2.27Ghz CPUs ESXi 5.0.0 Build 623860, built for IBM Hardware downloaded from IBM Storage: 2x500GB SAS local storage 8GB RAM Vt is verified to be ENABLED Server Health Status: Normal The ESXi host boots just fine. The Client connects just fine. Guests can be configured but do not successfully boot. The initial guest memory consumption jumps up to 560MB and drops down to 40MB after a few seconds. Initial CPU usage is 1 full CPU (3000Ghz per the chart) and immediately drops downm to 29Mhz. Guests do not display any output in the Console tab but show a state of 'Powered On'. VMs are listed as Version 7 and the behavior is duplicated across all availabled Guest OS flavors. Problem also duplicated when server is booted up in Legacy Only mode. Logs do not contain anything particularly suspucious. Edit: No firewalls, routers, or VLANs in between the client and server. Edit 2: We have tried to Boot Guest into BIOS screen at Next Boot checkbox in the Guest Setting. Was not successful. Edit 3: 500GB datastore with 1 40GB VM on it. Plenty of space.

• No video signal and server shuts down

  - by Ilya

  I have a brand new server. The motherboard is Intel S2600CP4, two 8-core Intel E5-2600 processors. RAM is 8 DIMM slots of 8 GB each (KVR1600D3D4R11SK4/32GI, I installed them into the blue slots), Power supply is 1050W Corsair. Most of the time the server won't start up - the fans are spinning, but I don't have video signal. And it keeps restarting on its own every 3 mins. But maybe after 30 mins it will eventually load and show something on the screen. I even was able to install ESXi 5.0 (vSphere) on it. It recognizes both CPUs and all of the 64GB of RAM. But even then it worked only for around 5 hours and then restarted on its own. What's the problem? That's a very expensive peace of hardware and I can't afford purchasing a new motherboard/CPU. By the way, on the front panel the "System Status" LED is constantly amber (not blinking), even when the server started successfully. And also in the BIOS I can see lots of "processor 01 unable to apply microcode update 8160" fatal errors. Please help me with issue, I will really appreciate this!
