Hello, first off I just want to say I don't know too much about computers, so if you have a response please tell me in detail. Thank you. i've been having this problem for a couple days now. I believe the reason why it went out was because I downloaded and installed a new motherboard driver. Tried to restart, and now it won't pass the Winxp load screen. I've been doing some searching on the forum and tried a few solutions but nothing seems to work. I booted the Windows XP cd, went to repair, and typed fixboot and then fixmbr. After that I restarted but i'm still having the same problem. I've also tried booting in Safe Mode, safe mode with networking, command prompt, and last known config. Another thing i tried to do was I took apart everything inside my computer to see if anything was loose or dusty. Any more ideas? I think maybe they're might be a problem with overheating, but I have no idea what a "normal" temperature might be. Please give me an idea then I will check mine and get back to you. Thanks in advance for the replys. My specs: (Had it custom built about 7-8 years ago.) AMD Athlon XP 3000+ Asus A7N8X-E Deluxe Radeon 9800 PRO 128MB Thermaltake 430W PSU 2x 512MB.. Xenon? not 100% sure.
