I have a problem with a PC (circa 2002) that belongs to my Father-in-Law. I recently added a 2nd HD and installed XP to SP2. I soak tested it and it appeared to operate fine (once I had cleared up the hudreds of reported viruses). I returned it to my Father-in-Law and after a couple of weeks it stopped booting. It gets as far as a screen with the old style bar filling from the left (didn't think XP had this?). The bar fills in approx 1/3 and then freezes. He says he hasn't installed any software and has had no further reports of viruses (using Security Centre and Norton Anti-Virus). The freeze happens at exactly the same point. I have tried booting into Safe mode, entering the BIOS, booting from CD but it also appears that the keyboard doesn't work. I have used this keyboard before so there shouldn't be any issues. Any ideas anyone?
