Try reloading the video driver. If that doesn't work then I'd guess they

Have DEll system with a geforce3 TI 500, all was dandy till the fan
stopped workin, GPU overheated and got a screen full of vertical red

called tech support, after getting me to run all sorts of tests they
eventually agree to send some1 out with a replacement card, which
worked fine for 3 days,
now the computer once it is booted to the login screen (win XP

told them i could get it running by booting in VGA mode, turning
hardware acceleration down 3 notches...
they said 'oh ok thats that fixed then'... now correct me if i'm

other one's fan went, but it was workin grand at full hardware
acceleration, how come this one isn't??
on another note, in the bios screen it has 'agp aperture' what does
