Iím having some PC issues and was hoping someone could help me fix them!
Last Friday I swapped an Asus HD 6770 for Gigabyte HD 7850. It seemed to work ok in Windows but crashed / froze in all games, benchmarks and when playing HD video. It would either crash to a black screen, or a green screen with dark green vertical lines. I tested it with the last 5 driver
versions inc betas but had the same problems each time.
So since nothing else had been changed, I concluded that the new GPU was at fault and RMAíd it on Wednesday. I then put the HD 6770 back in, uninstalled 13.3 ATI drivers
and then re-installed 13.1 or whatever the last non-beta was.
So after reverting everything back to how it was, I still get random freezes and BSODs when doing basic stuff like using Firefox, or even when the PC is idle, not just under 3D load as before.
I tried System Restore, Windows Repair, everything... but all with no luck so last night I re-installed Windows with nothing but mobo drivers and Firefox but the problem still persists! After anything from a few minutes to a couple of hours it will still freeze and either just hang on a unresponsive desktop, or a black screen where I can still move the mouse but nothing else.
Iíve ran Memtest86+, Chkdsk, and sf /scannow, all of which passed with no reported errors. Temps never get too high either.
It has only froze twice since re-installing Windows (once when trying to install Chrome and another randomly), but it didnít BSOD so unfortunately no minidumps available to analyse at the moment. I may have a few minidumps from the previous Windows install, but Iíll have to wait until later to check as Iím now at work (in zombie mode after being up until 4am trying to sort this damn PC!).
Last thing I did was put the GPU in the other PCI-E socket, swapped the RAM into different sockets and tested all cables and connections. There has been no crashes or BSODs since then but it Iím still thinking something hardware-related isnít right. I plan on running Intel Driver Update Utility when I get home, although Device Manager tells me all drivers are up to date.
The most frustrating thing is the has PC worked perfectly for over a year until I swapped out the GPU last week!
I know itís hard to say without any dumps to analyse but does anyone have any idea what might be causing all this? Hope I havenít fried my mobo!
