Hello all,

New to the forum, hopefully you guys can help resolve my issue(s).

Computer is an IBM Thinkpad T42

Here's the scoop:

I had a new hard drive installed at a local computer shop about a 2 months ago, Windows XP was reinstalled with SP3 current on my OS. Since then I've had the computer upgraded with an extra gig of ram.
Just recently, my computer has been doing a series of things that are pretty annoying, and I'm not quite sure what direction to point in. (i.e. software or hardware issue)

The Issues (All of which seem to present after a "Generic Host for win 32 process error")

-I get a blue screen screen every time I REBOOT, not boot, stating a "STOP: c00021a Fatal System Error". It does
nothing more than that. If I hit the power button from there, it boots normally.

-My audio will stop working; I won't realize it until I try and run iTunes and it prompts me saying that "iTunes has
encountered a problem with your audio configuration"

-My Windows theme will revert to classic.

-My wireless network selection screen will tell me that "Windows cannot configure this wireless connection"

-I get redirected to websites whenever I click links on Google (like trying to find a this website!

Microsoft Security Essentials was installed with XP when I got the computer back, but it doesn't pick up anything after a can, I still think there's an infection in here somewhere.

Note, all these issues cease with a reboot, but resume after about 1-2 hours of use, or being on.

Any help would be greatly appreciated...

Hello, first run an online scan to check if you have malware as when either Winlogon.exe or Csrss.exe fails you have no malware protection.

The STOP 0xC000021A error occurs when either Winlogon.exe or Csrss.exe fails. When the Windows NT kernel detects that either of these processes has stopped, it stops the system and raises the STOP 0xC000021A error. This error may have several causes. Among them are the following:
Mismatched system files have been installed.
A Service Pack installation has failed.
A backup program that is used to restore a hard disk did not correctly restore files that may have been in use.
An incompatible third-party program has been installed.

More info and troubleshoting...

Please perform a scan with Eset Online Antiivirus Scanner.
This scan requires Internet Explorer to work. Vista/Windows 7 users need to run Internet Explorer as Administrator.
To do this, right-click on the IE icon in the Start Menu or Quick Launch Bar on the Taskbar and select Run As Administrator from the context menu.

  • When the scan completes, push Posted Image
  • Push Posted Image, and save the file to your desktop as ESETScan.txt.
  • Push the Posted Image button, then Finish.
  • Copy and paste the contents of ESETScan.txt in your next reply.
Note: A log.txt file will also be created and automatically saved in the C:\Program Files\EsetOnlineScanner\ folder.
If you did not save the ESETScan log, click Posted Image > Run..., then type or copy and paste everything in the code box below into the Open dialogue box:

C:\Program Files\ESET\EsetOnlineScanner\log.txt
  • Click Ok and the scan results will open in Notepad.
  • Copy and paste the contents of log.txt in your next reply.
-- Some online scanners will detect existing anti-virus software and refuse to cooperate. You may have to disable the real-time protection components of your existing anti-virus and try running the scan again. If you do this, remember to turn them back on after you are finished.

NOTE: In some instances if no malware is found there will be no log produced.
