Hello everyone,
I have a strange problem with my computer. Every time I try to play a game, the moment the game starts (most of the time after the logo's, this is different for every game) my monitor seems to lose connection with my graphic cards. The entire screen distorts, sort of like static on a television, but very very bad. These distortions last for a couple of seconds and then my computer reboots.
My system:
OS: Vista 64 bit
Case: Antec Twelve Hundred ATX
PSU: Cooler Master Real Power M1000
Graphics: 2x HD4870X2 in crossfire
CPU: Q9550
Motherboard: X48-DQ6
The strange thing is: This system has been working stable for the past 2 weeks. I have completed Call of Duty 4, Crysis, Dawn of War and Kane's Wrath on it, and played several other games on it as well, without any problem (except some slowdowns in crysis and Kane's Wrath (with 100+ units on the screen)).
Something I've never been certain about is whether my crossfire actually worked, because I was never capable of setting fan speeds of both cards to 50%, only on two of the four gpu's. (when is try to modify the fan speed of my gpu's in the xml files the entire profile just stops working). In the catalyst overdrive, testing custom clocks is also greyed out for 2 of the four gpu's (number 3 and 4, specifically).
I tried 8.8 and 8.9b catalyst. Both have the same problem. When I deactivate crossfire, it seems like the games no longer crash, however, I have not extensively tested this.
After having reinstalled catalyst 8.8 (after having removed everything and running drive cleaner + some reboots inbetween) it seemed like it didn't happen anymore, however, about an hour into dawn of war and it happened again.
Possible causes I've considered:
- Card gets to warm: I set fan speed to 50% and regularly check temp, was never a problem. Besides, the problem comes up almost immediately (at first anyway).
-The PSU is insufficient: I'm not sure about this one. Is it insufficient? But why did it work stable for 2 weeks then?
So, any help would be appreciated
