Keeps resetting at login

[Twhite31]

So a few days ago my pc was running fine. The ONLY strange thing I can think that I did was attempt to connect the jumpers for the front USB drives on my case to the MB. All the sudden now, when I boot it starts fine. But right where it should go to the login screen, it force reboots and gives me the "windows did not shut down properly" message. It shows safe mode, safe mode with Networking, Last known good configuration, and boot normally. My components are all pretty new, within a year old. I have a GeForce 6800 vid card, 1.7 GB CPU, and only one HD. Any ideas on what may be causing this? I took the vid card out, and cleaned it and also attemped to clean the cpu. Any help would be greatly appreciated, I know pc's pretty well, but this has me stumped. I am able to access the BIOS, but I have not changed any settings and I have not reset it using the MB jumpers.

Will it start in safe mode?

No it won't start in any of the safe modes. If I select one it starts what looks like a bunch of operations that scroll to fill the screen. Once that happens it either reboots itself or I am forced to manually power it down. I can access the BIOS though.

If you have XP SP2, on the boot menu screen is a choice to disable restart on error - use that. Instead of rebooting it should bluescreen, write down what it says.

I will try that when I get home, thanks for the response. Which boot screen do you mean? It starts boot and I can press Delete to enter bios. After that is when if gives me the safe mode screen. Which of those do you mean? I have seen the bluescreen flash just before it resets.

The screen you get when you press F8 - the one that gives you all the choices - safe mode, safe mode with networking, VGA mode, last known good configuration, etc.

Ok, let me clarify. I don't have to press F8 to get that. When it boots I get a moment to press delete to enter bios. After that is gives me a message about windows not shutting down properly, bla bla. That is where my choices are Safe Mode, Safe Mode w/ Networking, Safe Mode with command prompt, Last known good configuration, and start windows normally. A timer is at the bottom. I saw nothing like you said. I did enter bios and saw nothing there like it either. If I choose any of the safe modes I get what I explained earlier. If I try to use either of the start windows options, it starts booting windows, I see a quick flash of a blue screen with some white text on the top, then it reboots.

Then you must not have XP SP2 installed. At this point you may have to do a repair reinstall of Windows.

[Twhite31]

I'm fine with that. How do I do that though. I already tried once by going into bios and changing primary boot to disc and having disc in drive. That didn't work, it just continued to boot as before.

[glc]

Are you watching the screen for a "press any key to boot from CD" prompt?

[Twhite31]

I just want to say thanks for the response and advice. I was able to change primary boot to CDROM in bios. Maybe last time I tried it was a bad disc. Anyway, it finally booted from the disc and I was able to run repair. Seems to have fixed the problem, because this response comes from my computer, yaaa! Thanks again, if I run into any other issues I'll be sure to come for advice.
