HELP!!! Windows XP BSOD at startup! (problem now solved!)

Hi all.

I am fairly new to this site. Saga Lout was very helpful answering my last 2 problems. Thought I'd post here again to see if anyone could help.

Well I ran windows defender offline and it found a threat which I quarentined. When I booted up into windows again I got a BSOD. I went for a week asking and searching about windows defender causing this bsod, you can view my question about this here: http://answers.microsoft.com/en-us/windows/forum/windows_xp-windows_programs/windows-xp-blue-screen-of-death-after-running/db46b582-52cc-4a62-ae2f-e12a9960d739

However windows defender WASN't causing the bsod b'cos when I restored the threat I still got it. It just must have been coincidence that I got bsod after quarentining a threat. Since then I've done a quick scan on malwarebytes and it found some threats which I quarentined.

The BSOD message I got was this: STOP: 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.


I've never got this message before and I don't kknow whats caused it. Certainely not windows defender removing a threat. Whats going on???????

Please view this youtube video for more info:

I've also uploaded event logs here: one of system: http://www.mediafire.com/?oqseng1cl7gcz9b

And one of application: http://www.mediafire.com/?di3dksn3hzny3kd

BTW, system restore doesn't work, calender is just blank, watch y'tube vid for more info.

VEry greatful for any help.

    this guy got it solved by himself
  5. Had a similar problem and kept getting the all zero error much like yours. I am running windows XP, Had SP1, update SP2, update SP3, all zero memory code meant I didn't have enough memory so I had to double it.
    I had to purchase two 512mb memory sticks and install, easy to do...
    Also had a conflict with two security's installed, had to fully get rid of one.
  6. Also you can run your test on XP.
    Press Start.... All programs... Hewitt Packard...HP Pavilion Tools... PC-Doctor.
    From there you can run test.
