Windows 7 64 bit ultimate

WD 1tb caviar HDD
LG Bluray/readwrite disk drive
Asus p8p67 pro motherboard
nvidia geforce gtx 570 graphics
intel i7 2600k sandybridge
corsair 550w PSU


Basically any game i've played lately, say:

Dungeon defenders. When the action gets thick enough, I get a blackscreen, and a message saying "No video signal".
MW 3. Just a few minutes into every game, same thing
Skyrim, hasn't happened here yet.


And I am just wondering, if maybe I need to upgrade the PSU? Or if it's legitimately my card. Sometimes the fan on the card ramps up to max, and sometimes it doesn't. I've had an OSD for heat monitor on since the first time, and it never goes higher than 61 C

Anyone have any sort of ideas? Any help would be much appreciated

If this is your PSU, you should have enough power:

That's it.

What else could cause it then?

The case is uncluttered, and dusted every week.

If it is with certain titles, I would assume drivers.

your problem is you got a 570 over a 6970 lol

Someone needs to retake 3rd grade English.

srsly

you don't need to put a period every 5 words. That isn't how periods work.

You caught me.

BACK TO THE KITCHEN WITH YOU!
