  • HP ML350G6 running hyper-V 2008 r2 resets itself every 2 hours

    - by GT
    The system started resetting itself exactly every 2 hours. These are the messages in the iLO2 log: Informational iLO 2 03/07/2010 20:40 03/07/2010 20:40 1 Server power restored. Caution iLO 2 03/07/2010 20:40 03/07/2010 20:40 1 Server reset. It's not an ASR reset (that would show in the log) Redundant power supplies, swapped but no change. Turned off all virtual machines (i.e. now only running hypervisor) but not OK Boot HP smartstart diagnostics disk, ALL OK Diagnostic disk reports no errors Went back to booting Hypervisor and the problem is back. Seems the hyper-V system disk has got a time based program (virus) causing the reset. I thought the hypervisor had a small attack surface and should be OK. All virtual machines (SBS2008, Win7 and Win XP) and network computers are protected with TrendMicro WFBS. I am about to rebuild the disk (I have backups) but wondered if there were any suggestions to try first???

  • Screensaver does not work for one user account, but does for the other

    - by Travesty3
    Both my screensaver and my "turn off monitor" power saver never come on for one user account on my computer, but it does for the other. It worked before. I can't think of anything I did just before this started happening. I'm using Windows 7 Pro SP1 with the default Aero theme, my screensaver is set to Mystify and should come on after 10 minutes. My power saver setting is set to Balanced, the Turn Off Monitor setting is set to 15 minutes, and the Sleep setting is set to Never. This all works absolutely fine on my user account, but if my wife's user account is logged in, it doesn't work. I don't have any antivirus, I'm not using a wireless keyboard or mouse, and I don't have MagicJack. I have restarted the computer many times since I've seen this problem. Anyone have any suggestions?

  • "setpci: command not found" in CentOS

    - by spoon16
    I'm trying to configure my Mac Mini running CentOS 5.5 to start automatically when power is restored after a power loss. I understand the following command has to be executed: setpci -s 0:1f.0 0xa4.b=0 When I run that command on my machine though I get bash: setpci: command not found. Is there a package I need to install via yum or something? I'm not seeing a clear answer via Google and I looked at the man page for setpci and it doesn't mention anything. Also, does this command need to be run every time the machine starts or just once?

  • How can I troubleshoot a "Hardware Malfunction" blue screen?

    - by AaronSieb
    My computer has suddenly started crashing to a blue screen with the following text: hardware malfunction call your hardware vendor for support *the system has halted* The crash occurs randomly during normal use. I have thus far always been able to reproduce it by transferring the contents of a large folder... But I'm not sure if this is caused by the file transfer, or simply because the transfer takes long enough for something else to trigger it. A bit about my hardware I have an dual core Intel CPU, and Asus motherboard. Video card is by nVidia, and connects via PCIe. My hard drives are in pairs, and connect via SATA to a RAID controller on the motherboard. They are configured to use a RAID0 configuration. What I've tried so far There is nothing in the Windows Event Log. WhoCrashed was unable to find any crash records. ScanDisk runs to completion (it launches prior to Windows load) and reports no errors. MemTest reports no errors (to 200% coverage). System temperatures are in the range of 40 to 50 degrees Celsius, with video card temperatures in the range of 60 to eighty degrees Celsius. I have stripped the system down to a minimal configuration (hard drive, video card, one memory module, motherboard, CPU, power supply). The problem still occurrs. However, this has allowed me to rule out a few components: It is not the video card because the problem still occurred after replacing the video card another one I had on hand. It is not the hard drive or anything software related because the problem occurred after a fresh installation of Windows on a replacement hard drive. It is not the hard drive cables because I replaced those with new ones and still had the problem. It is not the power supply because the problem still occurred after replacing the power supply with another one I had on hand. It is probably not the memory because I've tried three different memory modules in three different memory slots and was still able to replicate the issue. Is there anything I can do to confirm what's causing the issue? At the moment it seems as though it must be either the motherboard or CPU, but those are both difficult components to replace... In addition, both components are relatively new (two to three years old). I will gladly edit in any additional information I can get my hands on, and/or focus the question as I can find more details...

  • How can I unfreeze an SSD connected to a remote server?

    - by chmac
    I don't have physical access to the machine, so I can't unplug the drive. # hdparm -I /dev/sda | grep frozen frozen The advice I've read elsewhere is to hotplug the drive, pull the power / sata cables while the machine is running. Those are not possible in this situation as I don't have physical access. I've tried power cycling the machine through the host's control panel a few times, but that hasn't worked. Is there any way I can unfreeze (unfrozen?) the drive without physical access?

  • The difference between desktop-series HDD drives and server-series

    - by FractalizeR
    Hello. What are the main differences between desktop-series hard disks and server-series? The obvious things I can see are: durability (server hardware mostly more qualitative and have more warranty) and power consumption (server hardware more focused on performance, than on power economy). Also server disks are usually a little faster, but it seems, that it is not always the case. May be there are some other reasons, that make you choose server-oriented series (Seagate ES drives, for example) over desktop-oriented ones (Seagate Barracuda series)? What are they?

  • Fan twitches and LEDs blink when computer is plugged in

    - by Zifre
    I just finished assembling a desktop for the first time. The specs are: Gigabyte GA-H55M-S2H motherboard Core i3 530 CPU 4 GB DDR3 RAM 1 TB SATA hard drive 500 Watt PSU As soon as I plug in the computer, the "phase LED" starts blinking orange and the system fan LED blinks while the fan "twitches". This continues until about three seconds after I unplug the computer. This worries me a lot because I haven't even turned the computer on and it continues even after there is no power. I did make sure the PSU is on the proper power setting. What is causing this and how can I fix it? Is the motherboard dead?

  • Second Monitor Gets Bright, and then Blank.

    - by Jonathan Sampson
    I recently added a second LCD monitor to my home-computer. It was working fine for the first couple of days, but then it started having problems. Every 10-20 minutes it would get really bright, and then instantly go black. The power was still connected, so it wasn't turned off. If I turned the power off for a few minutes, I could turn it back on and get another 10-20 minutes of work done before it would happen again. What could cause this behavior?

  • Why Does Wireless Gear Degrade Over Time?

    - by bahamat
    I saw this originally posted on slashdot, but their comment format is not conducive to actually getting a correct answer. Having directly experienced this phenomenon myself, I'm now asking here where I think I can actually get an educated answer. Here's the original question verbatim: Lately I have replaced several home wireless routers because the signal strength has been found to be degraded. These devices, when new (2+ years ago) would cover an entire house. Over the years, the strength seems to decrease to a point where it might only cover one or two rooms. Of the three that I have replaced for friends, I have not found a common brand, age, etc. It just seems that after time, the signal strength decreases. I know that routers are cheap and easy to replace but I'm curious what actually causes this. I would have assumed that the components would either work or not work; we would either have a full signal or have no signal. I am not an electrical engineer and I can't find the answer online so I'm reaching out to you. Can someone explain how a transmitter can slowly go bad? Common (incorrect, but repeated) answers from slashdot include: Back then your neighbors didn't have wifi, now they do. They drowning you out. I don't think this is likely because replacing the access point with a new one and using the same frequencies solves the problem. Older devices had low transmit power. Crank that baby. As mentioned by a FreeBSD wireless developer this violates regulations and can physically damage the equipment. It was also mentioned that higher power in one direction is not necessarily reciprocated. This shows higher bars, but not necessarily a better connection. Manufacturers make cheap crap designed to wear out. This one actually may be legitimate although it is overly broad. What specifically causes damage over time? Heat? Excessive power? So can anyone provide an informed answer on this? Is there any way to fix these older access points?

  • Can't start my Windows XP Virtual Machine: Insufficient Disk Space

    - by Rob
    Okay, I currently have a server with two virtual machines installed on it, a CentOS5.4 and a Windows XP. I was remote desktopping the Windows XP chatting on IRC, and all of a sudden I lost connection. I checked with my HyperVisor and tried to restart it, and it won't start at all. It's giving me this error: Message from server0297.serverpool.gnet.ba: Failed to extend swap file (fileHandle 16414) from 0 KB to 524288 KB: No space left on device. Could not power on VM : No space left on device. Failed to power on VM info 4/17/2010 9:49:20 PM root Basically I bought the set up from a host, he installed the HyperVisor and the VirtualMachines, and honestly I don't really know what I'm doing. I've looked at some of the settings, and I can't figure it out. If you need any additional information, I'll try to provide it. The CentOS5.4 is still starting and working flawlessly, if that's relevant.

  • Could we build a mega-processor out of superconductors?

    - by Carson Myers
    A superconductor, once cooled below a critical temperature, loses all of its electrical resistance and therefore becomes 100% efficient. This means that when a current flows through a superconductor, none of the energy is lost to heat or light. Theoretically, could we build a processor out of superconductive materials, that could effectively run at, oh I don't know, say, 300ghz? or 5,000ghz? Since a superconductive circuit is 100% efficient, this means that once supplied with electricity, the source of power could be completely removed from the circuit and the current would continue to flow forever. So if we made all the components inside a computer out of superconductive materials, could we get away with only supplying power to the peripherals and save a-whole-lot on energy, while dramatically increasing computing speed? Might this be one of the next big breakthroughs in computing? What do you think?

  • ClearOS - how to avoid getting stuck at a fsck message at boot?

    - by Scott Szretter
    I have had this happen a couple times - I have a ClearOS Enterprise 5.2 box, and due to a power outage or similar, it ends up showing an error at boot and saying that fsck needs to be run (I think it said with (or without?) the -a parameter). The problem is, I need this box to be headless, at a remote location (miles away)! SO, I need to come up with a solution on how to either have it automatically repair itself, without someone to be present with a monitor and keyboard. Another possibility is to simply avoid the issue all together - maybe there is something that can be changed so it's very unlikely to happen (I am unable to avoid the power outage of course - at least not practically). Finally, maybe it can be boot off a read only media (cd) or file system or similar? At least the base OS, so that it would always at least boot with enough configuration that might allow remote access, or basic connectivity?

  • external HDD with SATA & USB interface? [closed]

    - by GregH
    Anyone know of an external HDD that would have (in addition to USB) a SATA (eSATA) port/cable? i.e. Brand/Model Background - In one location I want to use it is I would like to increase the performance by cabling it directly to the PC SATA port, HOWEVER I don't want to have to open up the PC to do this each time. I was thinking of running a SATA cable out through the PC case so I just plug it directly into the external HDD in question. Perhaps it should be also externally powered too so I don't need to run a power cable out from the PC power supply.

  • how to i lock a Harddrive to a certain drive letter

    - by Memor-X
    i have an external hard drive that i have set to Drive F which on it contains some programs that i have shortcuts on the desktop how i have a second external hard drive which i store my music on which is auto assigned to Drive E, due to someone thinking that Australians love to have f** wings on power plugs for hard drives while power boards have each socket close together i can have both of these hard drives set at the same time my music hard drive i normally only plug up when i sync music to my ipod but on occasion when i unplug my music hard drive and plug my old one back in or at times when i turn on my computer with the music hard drive in, turn off my computer and turn it back on with my old hard drive it's drive letter gets switched to E i get annoyed having to always go into disk management and change the drive letter back to F when this happens so i am wondering if I can lock my hard drive to always be F, if anything else tries to be F it can fail for all i care If there is a batch file i can use that'll go though all the steps of Disk Management to change a drive's letter, that way i can set it up in the startup folder

  • Problems with chip fan and CPU fan

    - by JS Bangs
    I have a five-year-old ASUS motherboard that has been working fine for me for years, until I attempted to power it on yesterday and got a CPU fan speed and chip fan speed warning. Cracking open the case and powering the computer on, I can see the chip fan working, but it appears to be hitting something as it makes a very loud buzzing noise. The CPU fan, meanwhile, starts up when I power on, but slows down and stops after a few seconds! How can I address these problems? Is there any way to fix these sort of fan speed issues without just replacing the fan (which in the case of the chip fan, probably means replacing the whole motherboard)?

  • Powerbook G4 unresponsive on wake?

    - by David
    I have a Powerbook G4 17" and I recently updated to the Mac OS 10.5.8 and got a monitor. I put it to sleep by closing the lid and sometimes it resumes normally and sometimes it doesn't. It doesn't matter if it's on sleep for a day or 10 minutes, it just happens randomly. It wakes up, but the screen doesn't flash blue for a few seconds like it normally would, indicating that it found the second monitor. It just wakes up, and a picture appears on both screens and the mouse moves, but nothing responds. The only way I can make it work again is by holding down the power button until it shuts down and then turning it on again. this frustrating because then I have to reopen all my programs and Safari tabs. I tried resetting the PMU by unplugging everything and taking out the batter, then holding the power button for five seconds, but it has the same problem no matter what I do.

  • Windows 7 PC crashes after being locked a few minutes

    - by White Island
    I have a problem with an Optiplex 755 PC running (32-bit) Windows 7 Professional. I just installed the operating system last week, and ever since, it seems to crash when I lock the screen. It doesn't happen immediately; it's usually after I walk away, so a few minutes (but I'm not sure exactly how many). I have this non-specific error in the Event log. I've run a chkdsk, thinking it might be hard drive-related, but that didn't help. Any ideas on what to check and how are appreciated. :) Log Name: System Source: Microsoft-Windows-Kernel-Power Date: 11/17/2010 3:09:28 PM Event ID: 41 Task Category: (63) Level: Critical Keywords: (2) User: SYSTEM Computer: WORKSTATION.domain.local Description: The system has rebooted without cleanly shutting down first.

  • Disk boot failure, insert system disk and press Enter.

    - by torbengb
    Similar to this related question, I came home and found that my media center pc showed this message, Disk boot failure, insert system disk and press Enter Before I do anything with the (defective?) harddisk, what are the best first steps I can take to fix this with a minimum of damage? Normally the machine (Win Vista) is always on and never reboots by itself (Windows auto-updates are disabled too). Something must have caused it to reboot, though I'm sure we didn't have a power outage. The machine can't reboot on that disk, but it will boot on another disk I just plugged in for testing. I haven't changed anything, or even touched the machine, for several days, and it has been running fine until now. I did replace the power supply some weeks ago, because the old one suddenly stopped working. It has been working fine with the replacement PSU.

  • Windows 7 boot problem on a Lenovo Thinkpad Z61m 9450HAG

    - by Matt Taylor
    Hello, I recently did a full upgrade of windows 7 on my thinkpad, everything worked fine after up until the second reboot (the first reboot after some updates installed worked OK). At second reboot time the system would just black screen just before the Windows logo appears, disk/wireless/power/battery lights are all lit and the disk light is active (flickering). However, if I remove my battery and boot with just power it boots fine and quickly, and everything is OK. Any help on why this wont boot with battery plugged in is greatly appreciated - i need to take this battery out on the road/trains etc.... Cheers Matt

  • My server freezes within a few hours of logging out. Staying logged in keeps the server running

    - by HappyEngineer
    I have an Ubuntu Godaddy server I use to host mail and webapps. It started having problems a couple months ago. It would lock up and stop responding to anything. I couldn't ssh into it, so I'd have godaddy power cycle the server. I have never seen anything that looked suspicious in the var logs (although I'm no expert at reading them). An fsck turned up no problems. Godaddy replaced the ram, but found no hardware problems. I started logging the output from "top" to a log file and found that even that stops running when the server freezes. Now, here is the crazy part: It got so bad that it would actually go down every few hours, but then it stopped going down. I eventually realized I had left an ssh terminal logged into the machine running top. This seemed unlikely to be a reason, but after the server was up with no problems for a full week (remember, it had been going down after just a few hours), I disconnected from the ssh session. Lo and behold, within a few hours the server froze again! I had them power cycle again and then left another ssh session open with top. It has been going without problems for 8 days now. I told others about this and they hardly believe me. I simply can't imagine what is going on. I don't know what else to try other than to just get a new server and reinstall everything. Does anyone have any ideas about what I can look for to determine what the cause is? Is it possible there's some sort of exploit on the server which only runs if everyone is logged out of the system? EDIT: The power management gone haywire sounds plausible, so I've modified the /boot/grub/menu.lst to boot with acpi=off and apm=off. It appears to have prevented kacpid and kacpid_notify from being in the process list, so I assume I did that right. I've disconnected all my sessions from the server. I'll check later tonight to see if it's still up. If it goes down then I'll try the pinging process idea. EDIT: It went down again. It lasted about a day. I've had them reboot, so now I'll try running "nohup ping -i 5 google.com &" and then disconnect. If it goes down again I'll come back. Hopefully someone will have some more ideas.

  • New graphics card (GTX 760) slowing down entire PC

    - by Cayetano Gonçalves
    My new graphics card is making my PC totally unusable. It boots up really slowly, and when the windows screen comes on, the mouse lags really far behind. Nothing opens at a normal speed. However, when I put in my 5-year old graphics card, it all works fine. I'm currently using a Foxconn Renaissance LGA 1366 Intel X58 ATX Motherboard, Intel Motherboard Intel Core i7-950 Bloomfield 3.06GHz LGA 1366 130W Processor, and a EVGA SuperNOVA 850G2 80PLUS Gold Certified ATX12V/EPS12V 850W Power Supply . I know it can't be the power supply, because I just bought it today to try to fix the problem. I've also installed the newest version of BIOS available for my motherboard. I've also seen extreme variations in CPU while the new graphics card is in, and when the old graphics card is installed, it is much calmer. Any thoughts?

  • How to prevent hard drive from spinning down Windows 7?

    - by JL.
    I had a Western Digital External 1TB drive, which I was accessing via USB. I decided one day, that I would prefer to mount the HDD in my case, and access it via SATA interface. So I took it apart, and the actual mounting was a breeze. The only thing is, I think the device has some default power saving features, which means the device tends to stop spinning when idle for (x) amount of time. This creates delays when I am accessing the HDD. Is there anyway I can turn off these power saving features for this HDD?
