Guys as you know, I recently upgraded my pc from core2duo to i5-haswell. along with mobo and ram.
Now, I have reinstalled windows twice, once windows 8, and then wiped it and installed windows 7, both 64 bit...but the same problem persists...display driver has stopped and recovered. No game is running. Direct x is latest, my amd drivers are the latest. Games won't even load till the main menu. First Alan wake was running but no other game was running, then I installed beta drivers, it started chopping up, I reverted back but it was still choppy. I wiped windows 8 x64 and then installed win 7 x64...Now, Farcry 3 is running, but there was a a lot of screen tearing. But apart from it, Black flag, Tombraider, Alanwake, Mass effect trilogy, Batman arkahm origins, street fighter 4 etc no game is running. I have been getting some strange errors when game starts and then aborts, these are:
Failed to lock the vortex buffer
Fatal error in Direct 3d
Driver has stopped and recovered.
Tomb raider has stopped working.
Some games give no errors, but the screen goes black and then nothing happens. The computer does not get stuck though...i can open task manger to get back to desktop....
I am at my wits end, I have installed the Beta drivers but they are no help either. I did think that may be the GPU isn't getting enough power..but I am not sure, how is Farcry running then?
4gb ram @1600
Cooler Master extreme power plus RS-500-PCAR-A3. (500w)
XFX HD 6850 1 Gb.
Do you think the GPU is underpowered? (I have no other PSU to check it). Or is it a driver issue? Before the upgrade, with my previous core2duo and ddr2 mobo and ram, everything was fine, I did get an occasional display driver has stopped and recovered message but it didn't hurt the games at all. Right now, I can't play anything and even normal window operations are being stuck in the display driver error. Please suggest...thank you.
