No you misunderstood me.

I did not say that their would be a problem with WinTVR I sad that if it was more and less that only app you had on the computer then It could be to consider a reinstallation of the system the fastest solution. 

What I instead was talking about that can be something to consider is it is necessary to have installed in the system was the Lucky Leap that I found in the Hijack log.

C:\Program Files\lucky leap\updateluckyleap.exe
C:\Program Files\lucky leap\bin\utilluckyleap.exe

This with the reason described below.

But nice that the "sfc /scannow" could fix the problem than it probably was some corruption in your explorer.exe file. that got fixed with the inbuilt system restore capability in XP.

Ok, you have chosen!

Devvie is out

Good luck!

@ devnullius way are you so aggressive in your comment her?

He have done both what you have suggested and what we have suggested so we don't know what chose he have done.

About a virus you can't regret that it could be a virus because their is so many virus out their that have fishy way to work and if it is not a good written virus or perhaps written for a earlier or later OS their can show up in very unexpected ways.
Even you are on that way in your comment that run the combofix.

Regarding memory fault their can also be that I have seen in my day very confusing behaviours of memory fault.

We just try to lookout for different reason that can coshed this problem we don't try to exclude any possible fault before we have checked for it.

@ maanas how match specials configuration or how match work is it to do a reinstall of the system? If you just have this system on the computer with the WinTVR you probably get up and running faster with a clean reinstall. If the problem then persist their is 100% that it is a damage HW or compability problem with some patches or software. But you don not probably get a answer what was wrong.

A other way to continue the fault searching is to continue with what have been written her before.
in the Command prompt run as devnullius wrote:
sfc /scannow

then, from safe mode when possible, run combofix
http://www.combofix.org/

You can also do a antivirus scan in the Safe mode be shore that you have the definition files for the antivirus updated to the latest date.


If this dose not work.
Then you also can do a half restore of the system files if you want to try that. To do that and restore all system files to the original. Do a cold boot of your system on the Windows XP original CD. Chose to repair the system and chose to rewrite the system files. After that do a reboot when asked for it and then you need to apply all patches in the system again. But at least you know you have fresh system files.

I have just take a fast look at you HijackThis
This is some I would look at first in the running processes.

C:\Program Files\lucky leap\updateluckyleap.exe

It's standard approach to these error, I would recommend him to run memtest86+ too :p

Maybe you can also run HijackThis and give us the log, so we can see if there's some fishy dll hooked.

chkdsk c: /f /v /x /r first (in cmd.exe prompt)

reboot

then, again, from cmd.exe: sfc /scannow

then, from safe mode when possible, run combofix
