XFX 6790 Blackout Problem

Forum Graphics & Displays : AMD Radeon XFX 6790 Blackout Problem

I have been having ongoing problems with my graphics card. I built the computer about 4 months ago and since then every time I play a game (any, doesn't matter about graphical quality) or even go online, it freezes, blacks out and comes back with a notification saying (Display driver stopped responding and has recovered).

I have been constantly asking forums and even taken the card back and they have sent the original back saying no fault.

There were rumours of something called "timeout delay and recovery" but there's no solution for that. It could also be power but when I go on AMD System Monitor the card doesn't even look strained.

Any help would be appreciated.
Thanks

I know you said it's not being stressed when this happens, but what are the temps of the card?

usually at about 48-49oC

Can you post a screen shot of hardware monitor voltages? something might be off, getting too much or too little voltage causing it to crash when going from idle to load.
