I installed the BFG 6800 GT OC and ran most games at the high end. Every now and then a game would lock up or have some graphic glitch like an added line or color issue. Usually could get it fixed with driver patch or a simple restart of the game. BTW-This happens almost entirely with multiplayer games.
I got BF2 and at first had a problem with the computer locking up but found a thread that suggested resetting default video settings and then putting them back to default. Go figure, it seemed to work.
I then installed COD UO. This game crashes 5 minutes into a game. Everything is fine up until I actually get into the game to play. The load up menus and picking of weapons has no problem.
Now BF2 is acting up again. I played for about 45 minutes last night and got the lock up. All I can do when it locks up is hard boot.
Here are the list of symptoms that occur:
Additional lines drawn in the game
Trees that look like they have Christmas lights on them
Distorted color up close but fine in the distance
Complete lock up with a jumble of color - Hard boot needed to restart
Complete lock up with jumble of color and high pitch screech through speakers
Complete lock up with jumble of color, sound loop, and regular sound
I have upgraded my soundcard to an Audigy 2 platinum, reformatted, updated all drivers, installed a new 480 watt power supply, moved cards around in the PCI slots, tried running the system with half the periphials unplugged. Nothing seems to help.
Also, the video card is an AGP and the mobo is MSI.
