• Computer hangs on start-up, but re-start always works

  - by user10604

  I press the power switch; the fans start whirring; then precisely nothing happens. The monitor lights (I have two monitors) blink to indicate that they aren't receiving any signal - no BIOS splash screen, nothing. This scenario occurs about 80 percent of the time, the other 20 percent being normal starts. Noticing that the computer has not started properly, I press the power switch for four seconds to turn the computer off, and then I press it again to start the computer for the second time. It always starts normally the second time. Always. The power supply is a 750W from SilverStone. The motherboard is a Gigabyte P55A-UD3P. The video card is an Asus EN9800GT. There's 8 GB of RAM. I don't know what other information might be pertinent. Help!

• Dell eSATAp not working with some SATA disks

  - by pistache

  I have a Dell Inspiron XPS 15 (L502X) laptop, with an eSATAp port. I also have a Western Digital 1TB 3"5 SATA drive, that I'd like to use with the laptop. I bought a eSATAp <- SATA 22-pin cable (from Delock). When I use this cable my 3"5 HDD does NOT power up, no spin up. I thought that it's just this HDD taking too much power from the motherboard. However, I tested too with my 2"5 SATA HDD and it works successfully. Now the weird thing is that this 2"5 HDD takes 1.1A at 5V, and that the 3"5 HDD takes 0.7A at 5V. I don't understand why it can't work. Is there anything I could do for it to work ? What is really the problem ? Thanks for your help, Hugo

• Is a "Soft Modem" (i.e. internal) really going to cause incompatibilities?

  - by Farseeker

  Thanks to the fact that our banking industry in Australia... outdated (which is the politest word I could think of when describing the banking industry)... to do a certain kind of transaction our bank requires us to use a dialup modem and send serial data to them. When reading through their documentation (last update: 1995), they state that any "Soft Modems" (by which I assume they mean internal modems, as they refer to a AMR socket on a motherboard, which I haven't seen in donkeys years) should not be used because of "possible incompatibilities" Seeing as buying an external, serial-port modem is actually quite expensive these days and I have a whole box of PCI modems taken out of a bunch of Dells I really don't want to have to buy an external modem. Additionally I think their documentation is simply outdated. Has anyone had experience with internal modems causing issues, where an external modem didn't?

• Workstation Build: Single 2.66ghz i-7 with overclock potential, OR Dual 5520 2.26ghz Xeons?

  - by jdc0589

  There are probably better places to ask this, but I am used to the excellent quality of responses on stack overflow. I am rebuilding my desktop in a few months. Aside from normal lightweight internet usage, I use it to run sqlServer, mySql, 1-2 Ubuntu VMs from time to time, lots of IDE's, and a media server for my PS3. The two possible setups cost the exact same amount (within $50) and would both have 12gb 1333mhz ddr3 ram and a 500gb RAID-0 array (250x2). Now, If I go with a single i-7 920 2.66ghz quadcore, I can easily overclock it to 3ghz, and would have cash leftover to get a 160gb ssd (either the ocz vertex or the 120gb intel) for the main OS/Program install drive. Else, I could get a dual lga1366 motherboard with two e5520 Xeon's (2.26ghz),just use the disks I already have. So, do I go for 8 physical/16 virtual cores at 2.26ghz (No overclocking on server boards) with normal disk I/O, or a 4 physical/8 virtual cores at 3.0ghz with really outstanding disk I/O?

• Why does Resource Monitor in windows 7 show half my memory as "Hardware Reserved"?

  - by Brandon

  Does anyone know why in Windows 7 Resource Monitor shows that I have 8 GB of RAM installed on my computer, but I only have 3.2 GB available as 4.8 GB are in "Hardware Reserve". I researched this issue and tried going into msconfig and making sure that in the boot options the number of processors and max memory options were turned off. I also opened the computer up and reseated each of the memory sticks while clearing out any dust that was in there. Some info on the system I am using: OS: Windows 7 Enterprise 64-bit Edition CPU: AMD Phenom X4 9750 Memory: 4 X 2GB DDR2 memory Motherboard: MS-7548 (Aspen) Any help would be much appreciated.

• Making an SSD drive the primary boot/system drive

  - by David Ebbo

  [Not much of a hardware guy, so please excuse my ignorance :)] I just ordered an HP Pavilion Elite HPE-450t (desktop), which came with Win7 installed on the hard drive, using two partitions (C: and D:). Separately, I bought a 128GB SSD that I intend to use as my system drive. I got it in there and connected it, and right now, it's the J: drive (which was the first letter available in disk manager). My goal is for the SSD to get a clean OS install be the C: drive, and to clean out the other hard drive and make it D: (for misc data storage) Question #1: the motherboard has two SATA plugs. Does it matter which one I use for which drive? Question #2: what's the right way to install Win7 on the SSD in a way that it ends up being the C: drive? Do I need to switch some things around in the current Win7 that came with it, are can I do all that while installing Win7 on the SSD?

• Why won't Windows use the other CPU cores?

  - by revloc02

  In Windows Task Manager the Performance tab shows the first CPU maxed out, the other 7 just idling along with the occasional spike. What gives? More info: I've got 8GB and only 4.5GB are being used. The Processes tab has no indication of any process hogging processing power. In fact System Idle Process is 98-99. When I program stuff and have like 8 to 12 applications going (several directly unrelated to programming of course) my computer slows to a crawl. Sysyem Info: Intel Core i7-2600K Processor (quad-core with hyper-threading), 8GB RAM, Intel BOXDZ68BC LGA 1155 Motherboard, 500GB HDD

• DH61AG's mythical 2 pin 19v power socket and is too low of votage bad?

  - by Nick Orton

  I have an intel dh61ag motherboard. It has an external 19v power adapter. It also has a 1x2 pin 19VDC internal power connector. Now I cannot find a psu or adapter or anything that will plug into this. In an intel forum, one person said that he plugged half of a 2x2 psu connector in and it worked. Since this would deliver 12v into a socket that asks for 19v, I suspect that this is a bad idea. I don't know much about hardware. Can anyone explain to me why this would be a bad idea?

• Windows freezes, showing a random color or pattern

  - by Manu

  I have a PC with windows 7, and I'm experiencing random freezes with increasing frequency. After some time (from 30 minutes to a few hours) the screen will shows a random color or pattern (vertical lines) and nothing works anymore, I need to reboot manually. I've checked the events log, but nothing is shown except for the unexpected reboot. I've tested the RAM with Memtest86+ 4.20, and the graphics card with FurMark 1.10.3, no errors have been found. I've updated the graphic drivers and openned the case to remove dust, but the issue is still there. Also, the problem doesn't seem to arise when I'm playing games fullscreen, but when I'm surfing the web, using itunes, or coding. My hardware is as follows : intel core i5 750 CPU, ATI Radeon HD 5670 graphics card, ASUSTeK P7P55D motherboard, two 2Gb KINGSTON DDR3 ram sticks, 2 SATA hard drives, a Netgear dongle for wifi.

• Bay Speaker Panel Installation

  - by JordanD

  I purchased a bay speaker panel that has a molex connector and a sound connector. Do I need to run the sound connector through my tower and somehow out the back into the IO panel? Or is there supposed to be a place on my motherboard for it to connect to? This is a replacement for normal desktop speakers for me to save desk space. Edit: Is there an adapter for the sound cable to the mother board? If so; what is it called? Thanks

• How to specify console (or primary display) for video adapter?

  - by Igor Zinov'yev

  I have an ASUS ENGT440/DI1GD5 video adapter which has three output ports: D-Sub (HD-15), DVI and HDMI. I am using both the D-Sub and DVI ports, but my main monitor is connected to the DVI output. Everything works fine except for which monitor is designated the console during boot. The video adapter seems to prefer the D-Sub output for the console. When both the VGA and DVI monitors are connected, then the VGA monitor always becomes the console which displays the motherboard logo, POST information and booting progress. When only the DVI monitor is connected, then it becomes the console as desired. How do I make the video adapter always use the DVI output (instead of the VGA port) for the console while booting?

  - by Killrawr

  I've installed Corsair Vengeance CMZ16GX3M2A1600C10, 2x8GB, DDR3-1600, PC3-12800, CL10, DIMM and my BIOS picks up that there is 16GB, Windows says there is 16GB, CPU-z says there is 16GB.

• When should I use SATA 6gb/s?

  - by Gili

  I purchased a Baraccuda hard-drive (model ST3000DM001) that supports a maximum read transfer rate of 210 MB/s and SATA 1.5/3/6 Gb/s. My motherboard has a limited number of 6 Gb/s ports so I'd like to reserve them for when it's really necessary. When does a hard-drive benefit from a SATA 6 Gb/s port? Doesn't it require a transfer speed of at least 375 MB/s to surpass the limit of SATA 3 Gb/s? Are there any other benefits of SATA 6 Gb/s vs 3 Gb/s ports?

• Why aren't there 8gb RAM modules yet?

  - by user49951

  Why is RAM module development seemingly stuck at the same size for a while now (a couple of years)? I bought 2x2gb modules 2 years ago, and now it's all the same size, with prices even bigger. I want more memory, because I work a lot on my computer and I just need it. What is going on? Hardware/memory progress was being made constantly until these couple of years, and I'm a big computer user for over 15 years. Why isn't here 4gb/8gb modules yet? I would gladly replace my DDR2 motherboard for a DDRX one if it had at least 4gb DDRX modules for a reasonable price. Now we have a situation with very cheap usb drives reaching 64gb size, and a ram modules with pathetic 2gb size. Sounds like some sort of conspiracy.

• Dual 9500GT video cards, one works

  - by bossDub

  I have two video cards, both are PCIe 512MB Nvidia 9500GTs. One is an Evga and the other is another brand. If I put them both in, the one in the top slot will work (either card). The one in the lower slot says Code 12, not enough resources to use this device. I've tried disabling Firewire and a few other things in an attempt to get more "resources". Intel DP45SG motherboard. 4G Ram. 64bit Vista. Q8200 CPU. I do not have the SLI connector.

• Memory works fine separately, but not together

  - by patersonjs

  I've been given four 1GB Corsair DDR2 memory modules, and am trying to fit them into my computer but am getting BSOD on Windows XP and errors in Memtest86+. I've tried to identify if one particular module is faulty by trying them in pairs. They work fine in pairs, but when all four are inserted, Memtest86+ reports errors. The motherboard is an Asus P5N-E with dual channel support and the modules are all the same model (same speed, capacity and timings) but one pair is a different hardware revision. One is v2.1 and the other is v2.2... the voltages are the same too. Would this minor difference be a possible cause of the problem? I've got the BIOS memory timing settings all at AUTO - should I manually set the timings?

• Windows XP crashes by GT610 driver (nv4_disp)

  - by undone

  I have a PC which was working fine but one day screen went dark and nothing was shown. I thought the problem is graphic card, so I replaced it with new one. I bought a new graphic card (GeForce 610) and installed it on my system. I formatted my hard-drive and installed a fresh Windows XpSp3 and its drivers. Everything was fine but after installing graphic card's driver, I got an error saying windows got stuck in an infinite loop and it couldn't get out (in nv4_disp). I uninstalled it and downloaded its last version and installed it. Unfortunately, I got the same error and windows restated! Here's my system: Pascal Motherboard PT880PRO Intel CPU Windows XPSp3 I searched this issue on the internet and I found bunch of suggestions (from cleaning hardware to installing latest version of its driver) but nothing help! Any help would be appreciated! Thanks.

• How to expand Raid 5 on ICH10 - Gigabyte ex58-ds4?

  - by NeverEatAlone

  I was wondering if there is a relatively simple way to expand my HD space. My setup is 4 x 640 GB drives. Motherboard has 4 ports on 1 controller and 2 ports on another controller, however they cant be joined. I would like to somehow get more store space in raid configuration. One scenario that I can see working is replacing one 640 drive for a 2TB drive. Waiting for Raid to rebuild. Rinse and repeat. However, I have no idea if I would be able to even see/access the new space. All alternatives / ideas are welcome. Thank you

• How can I re-program/flash a backup of the bios?

  - by user285705

  I have some computers that have a particular bios setting that keeps everything running smoothly. The setting is not the default setting for the motherboard. So, when the CMOS battery dies, the setting is erased and causes the user problems. How can I backup the bios and settings I have now, and flash that file onto my entire stock of computers? I have attempted to use awdflash to backup my bios and then attempt to write that backup to the ROM chip, but I keep getting an error. It tells me that my file number doesn't match the system, or something like that. Basically, the file is incompatible with the chip. But I just backed it up from that chip. If anyone can shed some light on this for me it would be helpful.

• Why can't I open programs after watching youtube videos for a while?

  - by manjivsanotsu

  I have recently built a new PC, and it worked fine for a while (1-2 months of no problems whatsoever). However in the recent weeks I noticed that after I watched some youtube videos and closed everything, I can no longer do anything except move the mouse and expand the Startup Menu. If I click on any of the programs on the Start Menu or type a program on the Run text box, it won't open anything. I can't open taskmgr, or windows explorer, or even shut down the PC. I don't have anything else running when I'm watching videos except ZoneAlarm and Avast. The only workaround I can do when this happens is a forced shutdown (holding the power button of my PC), and restart if I wanted to do anything more. But this happens a lot - about 4-5 times a week so I'm worried it would fry up my hardware if I keep on doing this. OS: Windows 7 Other Installed Software: Open Office, Tropico 4 game, Adobe Photoshop Browser used: Google Chrome Hardware: CPU: i7 2600K RAM: 16 GB Motherboard: Asus P8Z68-V GEN3 Hard Drive: 120GB Corsair Force GT SSD Graphics: 2047MB GeForce GTX 560 Ti

• Why is my PC boot time slow when USB HDD attached?

  - by John

  I have a USB Hard disk that I am using as a secondary drive just for extra storage. When this is attached and I start my PC the second screen says searching for mass storage dives for about 5 minutes before continuing on. The same happens when I have a USB pen disk attached upon boot. If I attach the device after the PC has loaded then it is very quick however plugging and unplugging is not ideal. Is there away to disable this in the BIOS as I cannot instantly see an option. On boot it informs me I have an American Trends AMIBIOS in the BIOS setup it states the version as v02.58 2006. This is running on a ASUS MV2 Motherboard.

• Disable writing RAID degraded mode

  - by jolivier

  I have a RAID5 with 5 disks on my machine and suspect the motherboard chipset to fail at some points and make my raid going in degraded mode. Last time it happened I noticed it on the failure of the 2nd drive connected to the same chipset and lost a lot of data. So I would like to prevent this, and especially I would like to have mdadm disable writes on the raid if one of the disk fails. So that in between I get notified, I recover and can use my system again. Sadly I could not find it in man mdadm so I was wondering if this is possible via a tool or hidden option since for me it looks like a standard feature of a RAID system. If this is not possible I would also be happy with a solution to stop the raid if degraded.

• No audio driver for ECS 7050-M v1.0a for Windows 7?

  - by NudeRaider

  I have an Elitegroup 7050-M v1.0a motherboard and I've used the Realtek HD audio driver it came with for years under Windows XP. There was a nice mixer panel, an equalizer and sound profiles that added effects. All of these menus are gone now that I've moved on to Windows 7 64 Bit. All I have is the basic settings under system control - sound, but they are not nearly as detailed. To clarify: Sound works, but the advanced settings I got when using older OS's are gone. Older drivers don't seem to work under Win7 and I can't find one for Win7. So how can I fully utilize the capabilities of my HD sound chip under Win7?
