windows xp problem i think

[etones]

i reinstalled windows xp on my dell, after i reinstalled it i installed all the updates including sp2. then i restarted my pc, when i got to the login screen the pc shut down then restarted then did the same thing over and over again. and its still doing it. one thing i have noticed is that when i turn it on it displays all of the hardware connected to my pc e.g. cd drive, keyboard etc. and its never done that before. help

Check your BIOS for inconsistencies. I know after I built my PC I accidentally set the CPU to 3000+ when it should have been 3200+, this for some odd reason created an infinite reboot loop when ever it got to Windows start up.
