Ok so it goes like this ... I am playing World of Warcraft when midway through the game my screen starts flickering and freezes twice (sound is ongoing in background but it also stops as soon as I try to ctrl+alt+del) with vertical lines on it. I have no other option but to restart PC only to have the same thing repeated. So I open up my cabinet, clean any dust up, change RAM slots, disconnect/reconnect cables, change PCIe slot of gfx card, etc. All this done, when I try to reboot again, my PC gives a BSOD immediately after 'Windows is Starting' screen and restarts. Upon restart, I find windows giving me an option of 'Startup Repair', which I use, to no avail of course. I try system restore from the startup repair window, to no avail again. It seems any try of normal startup just puts my PC in the BSOD, and I don't even get to see the welcome screen.
My GPU (Sapphire AMD Radeon HD 7770 1 GB) is powered separately by the PSU. I disconnected this cable and connected my monitor to the onboard vga adapter. Amazingly, my PC fires up just fine with on board graphics. However, any attempt to restart my PC with the vga and power cables attached to the AMD card just ends in BSOD like above. I have tried using AMD Cleanup utility to remove any remnants of old amd card drivers and reinstalled AMD drivers. The clean up runs just fine but during reinstallation I get error message 'Driver detection error. Contact AMD for assistance' and they won't install. On one occasion I managed to both enter windows and reinstall the AMD drivers (without any error message), but on rebooting, all I got was another BSOD. I have tried every step mentioned above once again after removing and reinstalling windows completely, all to the same result.
My rig isn't much:
Mobo : Gigabyte GA-B85M-D3H
CPU : Intel Core i5 4440 3.10 GHz
GPU : AMD Radeon HD 7770 1 GB DDR5
RAM : 8 GB Corsair Vengeance DDR3 1333 MHz (2x 4GB)
PSU : 650 W Corsair VS650
HDD : Western Digital Blue 1 TB
FAN : 3x Deepcool 280mm Blue LED Fan
OS : Windows 7 Ultimate 64 Bit SP1
PS : I do not use AMD Crimson drivers due to crash problems, etc. I have been using the last released version of catalyst.
Sorry for presenting the long post and pestering you. I am dead anxious that my GPU is broken, though I neither see any physical damage/wear in it, nor any abnormal behaviour (GPU fan runs just fine). If not GPU then what is the cause?
Please, please, help me out.
