ok, i have had my card for quite some time, around the begining months of the year. never had any problems and was quite impressed with it. now, it wont play quake 3 arena or rogue spear anymore. it plays fine for about 10 secs then throws a bunch of horizontal lines on the display and then just locks up completely resulting in a hard reboot. this is pissing me off greatly. it happened before i installed the current patches and it happend after i installed the current patches. i am running win2k and have been for a long time with no problems. help would be very much appreciated.
