CPU Intel Core i5 3570K s1155
GPU 3G Gigabyte HD7950 GV-R795WF3-3GD
MOBO Gigabyte GA-Z77-D3H Z77 MoBo
PSU CORSAIR CX 750W CP-9020061-UK
RAM Corsair Memory Vengeance Jet Black 8GB DDR3

I have tried numerous drivers/beta drivers from the Gigabyte website and AMD website and I'm pretty fed up (I even updated MOBO to see if that would help). I've tried it with MSI Afterburner on and off and it doesn't make a difference(not that I was expecting it to fix it). It has a lot of coil whining when gaming. For a short period yesterday it was working fine after I downloaded a beta driver 13.5RC from the AMD website however it has started crashing again. Just to give you a hint at how bad it is, it crashes whilst waiting for a game on Dota2 on the menus...

When it does crash the PC is still running however my entire System does crash (the display goes off, sound stops and also I had confirmation from a friend that I wasn't still on steam), however the fans are still running on the GPU/CPU/PSU/case fans etc so I haven't a clue!

I have read a lot on the web and a lot of people are having issues with the Radeon 7950 and I'm not the only one who is suffering from this crash however I'm yet to find a fix for it. Can anyone help? Have any ideas before I give in and send it back.

Cheers for any help!
