Alright I have a Windows XP system, and outa no where when I try to start it up-it goes to the loading screen, you know it says Windows Xp up top, little blue bar going through middle screen, anyways stays there for about 15 secs then a blue screen pops up and my comp reboots, ive tried Safe Mode, it trys to start up and stops at a thing called "agpcpq.sys" tried rebooting with previous good settings, does the same thing as normal-Is there anything I can do?
