Okay. I recently built a PC and today I started to install some games that demand a good graphics card (HL2, Fable, etc.) All of the games work for about 5-6 minutes. And then my CRT monitor either shuts off or it flashes violently until I close the game. When it shuts off I usually can't get it working again without restarting the PC. I've decided that the problem does not lie with the monitor as I have tested 3 different CRT monitors and they all have the same problem. I've tried: -Updating the Drivers -Running MemTest -Reinstalling the games I don't think the problem lies with the PSU since I don't have any problems with any other power hungry tasks (such as rendering movies..3D modeling...etc). My System: -200GB Seagate ATA -512MB PC4000 HyperX -Powmax 400w Power Supply -Chaintech VPN4 -Athlon 64 3200+ -Connect3D Radeon X700 Pro 256MB Please Help!
