One of my computers here at home seems to have a problem. Every time I turn it on, it has a DISK READ ERROR and asks me to hit control alt delete to restart. It will not load Windows XP at all. I have no idea what happened or why, and I need some help as to what I need to do to get this fixed. It's a P4 1.6A with an Asus P4B266 motherboard, 512MB ram. The hard drive is an 80GB Maxtor. I have never had any problems with this, and I really have no idea what's going on. HELP?
