    PLEASE HELP!!

    i have done everything i can find after searching the net for months including flash the bios with andros' rom and im still having problems. i have a p7805u fx laptop and i get this very VERY frustrating crash all the time. whenever i play WoW and city of heroes/villains my screen will randomly go black and hard lock the system. the only way to recover is to hard reboot (hold down power button till the system turns off and then manually restart). i monitor temps with gpu-z and they never get above 75C under heavy load. idle is usually around 50C. i have applied new paste to GPU, CPU and chipset and that lowered the temps a minute amount. i really dont think temp is the issue because sometimes it crashes at 65C-69C as well. case and fans are clean also.

    sometimes it takes roughly 20-30 mins before crashing and sometimes it is almost immediate after getting in the game and moving around a bit. i have also tested it with just cause 2, and to my surprise it runs fine! i can play that game for over 3 hrs without it crashing once.

    i have turned powermizer off, used all the drivers on the nvidia site as well as the dox drivers, changed to force performance3d in rivatuner and back to normal, flashing system bios to .17, compatibility mode on both programs on all versions available (adminstrator and themes disabled too) and at this point (after about 3 months of trying to fix it non stop) i have pulled out my final hair! i have also tried with fresh installs on both vista home premium 64bit and win7 home premium 64bit to no avail. ive ran memory tests for the system and never have gotten an error. it will never BSOD its always the black screen crash. i also have NO problems at all with anything else on this computer. youtube vids and flash work perfectly so i am totally stumped at this point.

    tnx in advance for any suggestions or insight on this matter

    Faulty gpu, cant do anything about it. If it is still under warranty try sending it in for repairs, maybe they will replace the mobo for you.
