Windows 7: Computer Blackscreening, not BlueScreen of Death.

03 Jul 2012   #1

Windows 64 Bit
Computer Blackscreening, not BlueScreen of Death.

My System:

Motherboard: AMD 990FXA-UD3
GPU: Gigabyte Radeon 7850 OC edition.
CPU: Amd 1090t Black adition
RAM: 4sticks of 2GB
PSU: TX750 Corsair
HDD: 1tb Seagate 7200RPM

My problem has been happening the last two weeks. What's been happening is that after maybe 20min to 1h of game play my PC screen will go black and either I will hear sound from my game or music, or I will hear a buzzing noise then it will stop sometimes. I am forced to do a hard reset on my PC. I only play Dota 2 and BF3.

What Ive tried so far.
- Testing my Ram with Memtest86 for about 8hrs. Found no problem and used the windows diagnostic memory.
- Testing my CPU with Prime95 for about 2h No problems.
- Tested my GPU with Furmark for 2h No problems.
- Tested my PSU with a PSU tester bought from store called Coolmax the voltages were fine.
- Tested my HDD no problems (forget what program)
- Reformatted still have had problems.
- Updated all my drivers.
- Uninstalled Video card drivers and reinstalled them.
- Disable onboard sound and still happened.

Now I am lost out of things to try. Ive googled a lot about this problem and seem to find no fixes that work for me. What else can I do.

Proper Hardware Checking:
This typically means hardware issues. You have already run some of the checks, but if you have not done the steps as described, please proceed to run the hardware checks again. For instance, Memtest86+ should run at least 7-10 passes, and the more the better. Prime95 should have each of the three tests run for a few hours each. Etc.
  • If you are overclocking any hardware, please stop.

  • If you have an SSD, make sure the following are up to date:
    • SSD firmware
    • BIOS Version
    • Chipset Drivers
    • Hard disk controller drivers/SATA drivers
    • If you have a Marvell IDE ATA/ATAPI device, make sure the drivers are up to date from the Intel site or Marvell site and not from your motherboard/vendor support site.

  • Run all but the advanced tests with SeaTools for HDDs.
    SeaTools for Windows

    SeaTools for DOS
  • Monitor temperatures during the following tests.
    Use the following programs to monitor the temperatures.
  • Run the boot version of Memtest86+ paying close attention to Parts 2 and 3 of the tutorial. Also, in case Memtest86+ misses anything and comes up with no errors, run the extended version of the Windows Memory Diagnostics Tool for at least five passes. These you may want to run overnight since they take a long time to complete (run them an hour before bed each of the next two nights and check before going to sleep that they are still running).

    warning   Warning
    Before you proceed with the following, answer these two questions: Are you still under warranty? Does your warranty allow you to open up the machine to check hardware? If you are unsure of the answers to these questions, contact your system manufacturer. WARNING: The steps that follow can void your warranty!!!

    For Part 3: If You Have Errors: If you swap any memory components, follow these steps for ESD safety:
    1. Shut down and turn off your computer.
    2. Unplug all power supplies to the computer (AC Power then battery for laptops, AC power for desktops)
    3. Hold down the power button for 30 seconds to close the circuit and ensure all power drains from components.
    4. Make sure you are grounded by using proper grounding techniques, i.e. work on an anti-static workbench, anti-static desk, or an anti-static pad. Hold something metallic while touching it to the anti-static surface, or use an anti-static wristband to attach to the anti-static material while working. If you do not have an anti-static workbench, desk, or pad, you can use your computer tower/case by finding a metal hold in it, such as a drive bay.
    Once these steps have been followed, it is safe to remove and replace components within your computer.

Hardware Compatibility:
We should also check your hardware compatibility:

Download and install CPU-Z and Upload screenshots of the CPU, Mainboard, Memory, and SPD tabs. In the SPD tab, upload an image of each slot.
