I am running Windows XP SP2 on Intel Celron 2.6 along with having with 512mb Ram in it. I'm trying to reinstall Windows Xp, but every time it start to boot. I even can't boot into safe mode. It loads drivers until AGPCPQ.SYS and go to black screen and starts to reboot again. So, can any body tell me that why it get hangs up while loading the drivers until AGPCPQ.SYS appears and go to the black screen? Do i need to install a new video card on my pc? Does any body knows about this issue? Kindly help me out to resolve the above issue.
