Hello.

I've been using my current setup for two or more years and all of a sudden, 2 days ago while playing a game, my screen went black and the PC has restarted itself. At first I thought it was a random BSOD, however upon reaching the login stage, the screen was divided by 7 white horizontal lines. After the welcome message appeared, the screen would go black and eventually the PC would restart.

After reinstalling the system and trying to pinpoint the cause, it became apparent that installing the AMD Radeon Desktop Video Card drivers causes this problem, however I have been using them for the past 2 years and the problem only appears now.

My current setup is:

AMD FX-4100 Quad Processor @ 3.60GHz
ASUS M5A78L-M/USB3 Motherboard
8GB DDR3 RAM
Radeon HD 6850 1GB DDR5

I have the latest BIOS update installed.

What can I do to fix this problem? I have considered ordering a new graphics card to see if it will work, but first wanted to get some input on this issue.

Thanks in advance.

try with another graphic card..
if it normal with the other card, then your old graphic card has fail..

well, what is your power supply..? bad and insufficient psu will cause bad card..
and do you always watch your gpu temp while gaming..? Too hot will shorten your graphic card life dramatically..

My power supply is 700W. I have observed my gpu temperature while playing many times and it was usually around 60°C-70°C.

hope that one is not generic power supply..
what is your power supply brand..?

just test your new graphic card..
if with your new card your system running smooth, well, yes, that's mean your old card is fail..

My mistake, it is Cooler Master: GX 750W bronze power supply.

I have not yet ordered a new graphics card as I am trying to decide between HD 7770/7790 or GTX 650. Something tells me that buying a new AMD card could result in the same problem.

After changing my graphics card from HD 6850 1gb to HD 7770 2gb the main problem seems to be fixed. However, a new problem has started occuring.
The system will run smoothly for some time, but then all of a sudden a BSOD will happen. After restart, the screen will either be all over the place with broken graphics or the system will continue rebooting. Additionally, graphics start tearing before BSOD happens.

The BSOD error codes so far have been: 116 and f4.

I'm using Windows 7 Ultimate and all drivers are up to date.
