Computer won't get past bootscreen, just reboots

[Static EMP]

Today, my computer started only making it to the bootscreen, where it would load for a while and then just reboot again. My computer was working fine before this. The last thing I did before this was uninstall a couple of programs (iMesh and WinCVS to be specific, but that shouldnt matter). It asked me to reboot so I did. I've tried safe mode, safe mode w/command prompt, debug mode, and last known good config, but the problem persists. Is there anything I can do to fix this? I can't use my computer at all now!

Thanks!

I had a similar problem that caused me to purchase new hardware, MB, HD Memory ect and it turned out to be a intermittent short in my reset switch on my case. After months of rebooting and frustration and money I disconnected the switch from my NEW motherboard and that fixed it.

Static - Windows is doing the 'ol Reboot on Crash routine that can be so annoying. The only problem is it is a major PITA to change it when your system is already broken.

So what your going to want to do is either:
1. Take the hard drive out of your PC and install it as a slave in another PC. Then get a good registry editing program and change the key below.
2. Get a PE disc like BartPE or MiniPE and boot into the PE off the disc and change the key below.

Browse to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\CrashControl
and change the AutoReboot key from 1 to 0.

Once you do all that you'll be able to see the STOP code that is being generated and using that we should be able to find out what the problem is

PS - if anyone knows of an easier way to regedit I'd love to hear it. I am pretty sure regedit is useable from the command prompt but I have never tried to edit keys from DOS or the recovery console.

I think you can only use Regedit for the registry in use.

There MAY be some third party yoots that MIGHT allow you to do this.
That would be a good idea if there was.
Will post back if I find sommat.

Aha,
First hit.
Maybe this would work without you having to take out the hdd and slaving it.....

Could have been caused by a variety of things including a corrupt registry, spyware, bad uninstall of an app.

The quick fix is to perform a manual registry restore which will allow you to boot into safe mode. From there you can use System Restore to go back to a restore point prior to the problem occuring.

Instructions for a manual registry restore here: http://support.microsoft.com/kb/307545

After restoring I would recommend a thorough spyware cleaning. Please follow my detailed instructions here: http://theflyingpenguin.com/spyware-removal.shtml

Then perform a FULL virus scan in SAFE MODE.

Hope this helps...

This is the STOP code:

c000021a {Fatal system error}
The Windows Logon Process system process terminated unexpectedly with a status of 0xc0000135 (0x00000000 0x00000000). The system has been shut down.


If any of you know what this means, and how I can fix it, that would be great! Thanks!

FP already gave you the fix for it, see for yourself. Before you do that you can try a more generic and less involved fix, if you find the MSKB resolution rather involved. Boot from the XP CD, hit R for the recovery console, then type chkdsk /r. When its done, type fixboot, then reboot and see if you can get to desktop. If it doesn't make it the more involved registry restore is the ticket.
