My friend's windows XP was running very slowly so I stripped it back of all unneccessary programs and reloaded the XP software from a legal disk.
It seemed to be working until it shut itself down and is now stuck on a loop I can't get anywhere near the desktop but can get into the bios. I have tried reseting the computer from there but it continues on the loop automatically reseting what I have done. The CD has worked before so I don't think it was that which caused the fault. Any ideas on how to fix the problem will be greatly appreciated.
