Hi All,

Im having problems with windows xp and my graphics card... well i think thats what it is, basically i had a pc running winME so i formatted it and installed XP pro with xpsp2 on it. It installed fine i ran windows update with no problems it ran for a day then i shut it down. when i came back to it 2-3 days later and booted it back up. it booted into windows at a resolution of 640 x 480... with 4 bit colour. i tryed rebooting and it came back with the same resolution but normal colours. As soon as i tryed changing the resolution the colours changed back to 4 bits. I tryed rolling back thinking it was a windows update error. However that didnt fix it. so heres the next part been a brand new installation i figured i may as well just wipe it and start again... as soon as the XP setup started i have random flickering of red box's running down the screen during the installation and whenever i move the mouse.

Please Help

I also forgot to add that i have tryed installing drivers (the latest from nvidia) and it just reboots during the installation. It then won't boot up just reboots again until you get into safe mode and manually remove the device then it comes back up. However with the same problem.

I would lean toward a bad videocard...do you have a KGP (known good part) you can pull from another machine?

Check the videocard...does it have a gpu fan? Is it clean and spinning freely?
