Hello can someone understand this problem. First I couldn't get my HD7950 to work with Asrock z68 Extreme4 Gen3, I had to update the Bios to 1.10.
Since then its been working great playing games no crashes perfect. So last night I bought Crysis one from steam and at the beginning on the game on the beach my Display just switches of and says No input signal so I turned pc off and it was still doing it?
In the end it was abit late so I left it till this morning and when I first switched it on it worked first time?

What could be the problem here? is my PC trying to switch to on-board GPU when playing crysis.

thanks for any help.

Theses temps abit high? for just browsing web?
 
Just ran Prime95 and 5mins later it done same thing so it looks like it's CPU. Just just on H80 and the paste isn't over all CPU I put small blob in mid but it seems to have gone more over one side?

Could this be the problem.
 
Anyone? I will re do paste later. Question about bios CPU settings should they be anything I should have to change right out the box? I haven't done any overclocking to CPU all I have done is changed boot order and set ram to XMP. Is that all I need to change?
 
Try re paste, a small in the middle usually works well for me. Those temps seem a little high, but load temperatures are usually more useful!

So it crashed after 5 mins of Prime? What were the temps like?

If you're not overclocking you shouldn't need to change anything. This says to me that the cooler just wasn't on properly. Reseat the cooler, with fresh paste. Then try Prime again while monitoring the temperature.

Thanks will do. When I un screwed cooler it seems I have tightened up one side more than the others, that's probably why paste was more on one side.
 
Yeah, tighten them evenly, but don't tighten one completely then the next.

Tighten one a bit, then the one diagonal to it. Then the other two. Keep repeating this til they are all tight.
 
It's covering most of it, so should be okay.

Did you follow the sequence I said?
so tighten them in this order:
1 3
4 2

Also, how much are you putting on? About a pea-sized amount is plenty. You dont want too much.
 
I not tried doing it again yet in work thats what it was when I removed it this morning. Ill try doing what you say later and one done am going to run a ram test first see if thats ok then prime95.
 
I dont understand how playing games like team fortress 2/war inc ran fine? but crysis rashes right away, is crysis more heavy on cpu or something?

Memtest passed two passes without error and I just ran prime95 small for 30mins and passed ok on that. Can someone tell me if my temps our what the should with a H80 on medium fan setting?

Thanks
 
Just started crysis and this time it went on for longer and thought yes its working. couple mins later bang black screen? no warning nothing?
What could be doing this please help someone?
