I'm really hoping someone can help me out here, and the sooner, the better. I've checked the archives, and while I've seen that people have had similar problems, my situation feels a little unique. The problem? Windows XP keeps rebooting, over and over and over. It starts the computer in safe mode, does a scan disk, fixes any errors (sometimes it finds some, sometimes it doesn’t), brings me to the log-in screen where I type in my password, and then it reboots again. I’ve done this over and over and over. I’m letting it go because it seems like it’s fixing different errors each time, and I’m hoping (in vain?) that it will fix whatever the problem is and let me back in so I can at least back up important files. I’ve seen the desktop once since this all started (and I’ve probably rebooted the computer twenty five times, at least, by now), and I was only in there for about five seconds before it decided to reboot (again!). I don’t have any problems with the computer overheating nor do I have any viruses (at least, none that my antivirus program has caught). I did install a program right before this happened, and I wonder if that’s what set it off. I want to be able to get back into the computer so I can uninstall it. Any idea to continue rebooting? What should I do? Help, please!

You may have already thought of this: press F8 before Windows XP gets to the loading screen (with the moving blue bars) and then select Last Known Good Configuration. If that fails, try Safe Mode also.

As mentioned above, it *is* booting in SafeMode (automatically). I have also tried "last known good configuration" with no luck. Any other ideas?! =/

Is the reset button on the box jammed?? Perhaps something is damaged on the motherboard. Just a guess; I'm no expert

Nope, the reset button seems fine. Thanks for trying. :)

When it gets to the screen where it wants to check disk for errors...it gives you the option (displayed for just a few seconds) to skip the error check...sometimes works if you skip the check...I forget what key you need to hit but it will say on screen. Hope it works so you can remove the program or do a system restore. Before doing that...since its been rebooting so much..mabye best to turn it off and let things cool down for a bit...all that rebooting will produce a fair bit of heat. Shut it off, pull the plug, and leave it for about half hour, then try booting to safe mode so you can do system restore to before you installed that program. What was the program called that you installed?
