Sapphire HD 5770 crashing

Hello :)
Recently, while playing graphically intense games, my system has been crashing with no BSOD. (simply, just turning off) My first reaction was heat, so I began to watch my temps. They never reached my emergency turn off levels set in the BIOS. I then figured my PSU was not strong enough to handle 100% load, so I upgraded to a 600W PSU. (rated far higher then what my system pulls) The error still persists... so, I updated my M/B BIOS, update my VBIOS, ran memtest (with 0 errors over 4 hours), ran prime95 (4 hours with no system crash), ran furmark3D (for 30 minutes, no crash) It usually crashes within 10 minutes of playing, for example, Need for Speed ProStreet. Keep in mind, this game is rather old and a lot less demanding then other games. It will also crash playing Medal of Honor for about 10 minutes or so. Playing World of Warcraft, it usually won't crash. (though it happens rarely) Scouring the system event logs proves fruitless. With no BSOD, at that, I assumed it would have to be a hardware issue. (yes, I have it set to show BSOD instead of restarting immediately)
What should I do? :x

You can try that...
ATI driver install assistance
---------------------------------------------------------------------
(Sometimes this happens from high CPU temperature)
Are you sure ur CPU temp is the right one?Because a friend of mine had the same issue and at the end was a high CPU temperature problem.
Test ur CPU temps with this Core Temp
Download the 64Bit version.
-----------------------------------------------
If you want to control ur graphic card temp in ati ccc enable the Ati Overdrive,DONT touch anything else just enable the fan control and set it accordingly ur needs.

The best drivers as of now are the 10.10 all other versions after suck .

I tryed all drivers from here on after and all of them are unstable.

I have had the same issue random bsods games just disappearing ,even some games the bosses were invisable but everyone else in co -op can see him .

I hope they get this resolved it is alot of money being pumped into these things and they still can't get it right ,,,,,,,,,,,,,,most likley you will have to revert to a old driver even 10.9 works on the hd5770 after all i still own one so try the 10.9 or 10.10 you won't crash anymore


GoodLuck !
