Hello,

I am having major issues with starting up my laptop. It is a Dell Inspiron 6000 running Windows XP and just recently had an automatic windows update (other than that, nothing has been downloaded recently).

When I try starting up the computer, it gives me a blue screen of death when the windows LOGON page is SUPPOSED to load. The BSOD gives me the error code STOP: C000021a, and that a "fatal error has occured". It also gives this code: 0xC000012f.

I have tried booting in safe mode, but no success. Have also tried booting from the last known good configuration, but also with no success. Any suggestions on how I can resolve this problem??? Is it possible to resolve this issue without losing data on my harddrive?? I'm hoping it's not serious enough to require a reformat .

Thanks in advance!

Note:
A Repair Install will replace the system files with the files on the XP CD used for the Repair Install. It will leave your applications and settings intact, but Windows updates will need to be reapplied.

I just did the repair install as you had suggested. But after the system restarted, I ended up with the same BSOD, with the exception of one code.

Previous BSOD: STOP: C000021a, and that a "fatal error has occured". It also gives this code: 0xC000012f.

Current BSOD: STOP: C000021a, and that a "fatal error has occured". It also gives this code: 0xC0000135.Unfortunately the blue screen is what most windows users dread! If the repair install did not work I would suggest typing the error into a search engine such as yahoo and do some research on the problem. If it comes to worst, you will have to reformat. Unfortunately, if you ask me, a CLEAN install is always RECOMMENDED. It will be sure to fix your problem.
