Games make desktop resolution lower

July 24, 2010 at 06:16:54
Specs: Windows XP
After an hour or so of playing any game, it and my mouse suddenly stop responding (sound keeps playing), then my monitor flashes 'no signal', and several seconds later the game is back up - but my desktop resolution is now at 1024 x 768 instead of it's usual 1280 x 800.

If I keep trying to play the game, the same thing happens again w/in a minute, then the game stops responding completely + has to be closed w/ Task Manager. The game won't run normally again until I reboot.

If I just exit the game once this happens the first time (which I *usually* have a chance to do), then I can put my screen resolution back up to 1280 x 800 via Desktop Properties... But I have a lot of icons on my desktop and trying to get them back in their proper places (after low res. has shuffled them around) is very annoying.

DxDiag always tells me 'no problems found' even after these crashes, but I recall a while back seeing an error popup re. "D3dx10_41.dll Not Found" after one of these game/display crashes...

My PC is otherwise running fine, so I hope there something I can do other than reinstall Windows. Any suggestions?

Do a check on your system with this tool first. You didn't mention your power supply specs. The 4650 will run on a 400 watt power supply and draws it's power from the board. What game are you trying to play?
