I tried to load up my computer (emachines 390) and it keeps restarting when loading windows xp. It finally got onto windows main menu, so i saved some of my files to cd and decided to reboot windows by putting in the restore cd's that came with it. When i try to load it now, the windows loading page thing comes up and then the tower makes a sound like it is shutting down and it restarts. Its not a sound from speaker, just can hear the computer fan or something slowing right down. Do i have a hardware fault or something? please reply asap, i REALLY need my computer
