I wasn't sure where to post this as it's not really virus related.

I've come here before and you all have always helped me solve computers issues beyond what I understand. Right now I'm at a complete loss trying to fix my mothers PC. She recently got the virus, not sure its name, that puts all your files to hidden and tells her she needs to buy this antivirus. She claims this issue has been happening since that. I saved some files she wanted and we did a complete re-install of Windows 7. everything worked fine for a bit and then the restart loops. I have no idea what she did, since she insists it's related to that virus she got..even though we did a clean re-install.

The computer starts up, loads to a blue screen STOP c000021a FATAL ERROR ect.
Then shuts down and asks to start normally or run repair.
Repair says it can't figure out why the computer fails to start and leaves you sitting there. I've read on some places that you need to reinstall the OS. Well we did do that but now we can't at all. I put the CD in to boot from CD and it shuts down before it finishes loading. I mean loading as in select boot from CD, press any key, key pressed, please wait loading - computer then shuts off.

So we're stuck in an endless repair restart loop, with the computer shutting down trying to install a new OS.
I managed to take two pictures because the error only shows for a good 3 seconds before the computer restarts. It seems to alternate between two different ones or shows no error at all and restarts.

I guess no one has any clue what I could do to fix this?
We managed to get it to stay on after going through startup repair a couple 1000 times and getting it to restore to day 1. If it runs autoupdate it crashes and does this blue screen loop so we disabled those as well.

0xC000021A: STATUS_SYSTEM_PROCESS_TERMINATED
(Click to consult the online Win XP Resource Kit article, or see Windows 2000 Professional Resource Kit, p. 1561.)
This occurs when Windows switches into kernel mode and a user-mode subsystem, such as Winlogon or the Client Server Runtime Subsystem (CSRSS), is compromised. Security can no longer be guaranteed. Because Win XP can’t run without Winlogon or CSRSS, this is one of the few situations where the failure of a user-mode service can cause the system to stop responding. This Stop message also can occur as a result of malware infestation or when the computer is restarted after a system administrator has modified permissions so that the SYSTEM account no longer has adequate permissions to access system files and folders.


First thing I would do since the system is running is have it checked out by our trained malware techs.

I suspect that you have some malware on your computer causing issues that we are not able to solve through means we can use here in the Tech Forums. I suggest you read the 'Start Here' topic found HERE. With these self-help tools you have a high chance of fixing the problems on your own. If you are still having problems after following Step 3 of the guide, continue with Step 4 and 5 and post in the Malware Forum. If you are unable to run any programs, Please create a topic stating what you have tried so far and that you are unable to run any programs. Also, Please do NOT post the logs in this thread.

If you are still having issues after the malware expert gives you a clean bill of health, Please return to THIS thread and we will pursue other options to help you solve your current problem(s).
