Hi, I've been having some trouble with my computer lately. It crashes/freezes randomly. The screen is frozen for a couple of minutes and the sound hangs/loops. Mouse and keyboard stops responding, then the screen turns black. Sometimes I get a BSOD, sometimes the screen remains black. This usually happens when the computer has been on for a long time, or if I have a lot of programs running or playing some games (happened twice in PlanetSide 2, once in Battlefield: Bad Company 2, a couple of times in Garry's Mod...). When this happens I have to restart the computer by pressing the power button.
I have set the computer to create minidumps.
Automatically restart is unchecked.
Write debugging information is set to "Small memory dump (256 KB)"
And Small dump directory is set to "%SystemRoot%\Minidump"
But it still doesn't create minidumps. I have checked inside the Windows directory and there is no minidump folder and no .dmp file.
I checked the Event Viewer and found that when my computer is crashing it creates an error with the Event ID 6008 and one with Event ID 1101. And sometimes a warning with the Event ID 219.
I ran memtest86 for 8 passes. No errors.
I ran checkdisk. No errors.
I have updated all drivers. Uninstalled and reinstalled display drivers. I even did a clean install of Windows 7.
My temperatures are fine. Everything is <40 degrees celcius.
My computer is an Acer Aspire AM3920. I've had it for 16 months. I replaced the graphics card and the PSU with better ones, but that's 5 months ago. Everything else is stock.
I've never had any trouble with it until now.
I'm running Windows 7 Home Premium SP1 64-bit
CPU: Intel Core i3 2100 @ 3.1Ghz
Motherboard: (No specific brand, I guess. Acer Aspier AM3920 according to CPU-Z)
PSU: Corsair GX600 @ 600W
Graphics: Sapphire Radeon HD 6870 1GB
RAM: 6GB DDR3 (3x Samsung M378B5773CH0-CH9 2GB DDR3 1333MHz)
HDD: (Don't know, but it's 1 TB)
Does anyone know what's causing it to freeze/crash/stutter/BSOD? Is it bad RAM, bad PSU or is it something else?
Could be hardware failure (I am thinking the graphics card). To check, replace the card and see if any more crashes. I had similar issues, as well, and it turned out the graphic card needed replacing.
Before that, run some graphic-intensive benchmarks (3dMark, for instance) and see what happens.
I ran 3dMark and Unigine Heaven and it didn't crash.
I just got a BSOD again. This time was just browsing the internet. The whole Windows process just died. The task bar disappeared. Everything else worked fine, until I tried to Ctrl+Alt+Del. Then the screen went black, and then the monitor lost signal to my computer, and then a BSOD appeared on my screen.
