Hi Allan, thank you for your response. Here is all of the info required:

1. I am running Windows XP and have service Pack 3 installed a while ago.  Worked fine when I did that update.
2.As for an antivirus, I have Avast installed.  I was able to run a scan a few DAYS ago and it found nothing.  The computer shuts down now before it is able to complete the scan.
3.Firewall, I'm not sure if I have a firewall other than the XP firewall. Not sure I should do this now given how overtaxed everything is. Obviously, I'd like to download it once the computer is running ok.
4. I went through the list in my add or remove feature but did not find anything on there that is malware.
5.CCleaner.  I was able to download this successfully and then run it.  Cleaned out the registry per the instructions.
6.  SuperAntispyware.  I was able to download the program but the computer KEEPS shutting down before completing the scan.
7.Malware Bytes..I was able to scan this and it found nothing in the quick scan. Itried runing the full scan and the computer keeps shutting down before completing. No errors were found up until the pont it shut down.
8.HiJackThis .  I was able to run this as well and included the log below. I was not able to us the self help tool as it also shut the computer down before completing.
9.  I have he most recent Java and Adobe installed

As an additional NOTE, the initial part of turning the computer on works fine.  The problem occurs after logging on and booting up fully.  Once the computer is fully booted up  can hear the computer running as f it is going at a high speed (fan?) and it doesn't stop until it soon shuts the computer down.  I tried removing all the fans and the video card and cleaning them out to make sure it was not dirt or dust.  They seem be functioning properly.I asked for this?Yes, I posted yesterday and you referred me to your page with the LINK of what to do.  I went through everything.  It took me 5 hours but I tried as much as possible and I tried to be specific about what I was able to do and not do.  ou asked that I post it in a new thread.Please follow the instructions in the ORIGINAL thread and post your logs in the forum indicated in that post. Thank you.Forgive me.  I am not sure which forum you are referring to where I should post.  The link you provided links me to the instructions page I followed step by step.  Can you guide me in the right direction asto where to post?Ok I think I got it and  posted it on the virus and spyware removal forum.
