Intel E8400 @ stock
2 * 2GB Kingston ddr2 800
Maxtor sata 250GB
Tooq X-Power 8000 800W PSU
Original gfx card - Gigabyte Nvidia 1GB pre Overclocked, cant remember exact model now
New gfx card - Asus GTS250 512MB
My friend recently had a problem with this tower when playing CoD that would make it reboot. Over time it got worse and worse until the point the screen was always scrambled, even on the BIOS screen. By the time he asked me to have a look the gfx card fan was not spinning, so I removed the graphics card and using the onboard gfx the screen was correct but Windows XP refused to boot.
We decided that as he needed a new gfx card now would be a good time to upgrade to Windows 7 as well. I installed everything OK without problem and did approx a 16hour stress test with Prime95 and the freestone graphics card stability test - all OK.
About 2 weeks later he rings to say it has restarted a few times while playing the game, sometimes Windows came back up sometimes it didnt. This got worse over the next few weeks, until Windows would no longer load.
Then I decided to reinstall XP and just use the onboard gfx. This all went well, and I did the same stress test for over 24 hours, all OK. But then the next day it refused to start up with a BSOD 0xF4, cant get into safe mode or normal.
I have ran Mem test+ with both sticks of RAM and also with just one for over 24 hours each time and no errors.
I have scanned the hard drive for bad sectors and it passed.
Without just swapping parts out I am not sure where to start….
PSU? For info both gfx cards require 1 PCIe power
Any help is much appreciated
