Hp Pavilion 522n

have you tried to boot in safe mode and run a virus scan you might just have the sasser virus. is your internet connection firewalled?

Once you restart the computer press F8 once the screen comes up click on the last known good config. that worked and follow the directions. Hope this helps if not then you might have a virus.

When you format to start over, do you fdisk the mbr? If you did have a virus, a lot of them stay in the mbr, so every time the computer reboots, so does the virus. fdisk /mbr. The only other thing I can thing of off hand, would be maybe your mobo is scratched somewhere, or bad. You can try pulling it out, putting it in another tower, and see if it does the same thing. Sometimes some things just don't get along well toghether, for some unknown reason also. Hope you get it figured out. Good luck. Bev
