H, Sorry to hear of the troubles with your machine.
1 There was no response from you to Ken's last suggestions in your recent malware thread here:

This will start ComboFix again. After reboot, (in case it asks to reboot), post the contents of Combofix.txt in your next reply together with a new HijackThis log.
2 If you need further help with checking for malicious or undesirable elements, then you will need to open another thread and post an HJT log in the malware removal forum.
3 As some of the symptom you describe are consistent with a hard drive that is about to fail (it is not certain that it is about to die, but a strong possibility) it would be wise for you to consider taking the opportunity to bring your back up/archive/copy of all your important stuff 100% up to date, check that it's accurate, reproducible and held securely on removable media (not your hard drive)……the idea here is to ensure that all your important data, files, spreadsheets, work, music, emails, log in details, user names, address book, drivers, letters, invoices, videos etc….in fact everything that is important to you (stuff that you would not like to permanently lose) is safe on external media. Whilst you are doing this collect together all your application installation discs (or downloaded installation executables) serial numbers, product licence keys (including the one for Windows itself and the Microsoft Windows XP installation disc and or Manufacturer's Restore and Driver /utilities disc.
4 Your logs indicate that your machine, has had P2P File sharing programs installed……..There are legitimate uses for P2P File sharing, but a lot that I come across are used for the downloading of files, (especially music, videos, games etc) that breach both National and International rules on copyright. There is currently a major crackdown on folks who use File Sharing to break copyright rules and heavy penalties are being imposed……often it's the young folks who are tempted to do this, their parents and elders often being unaware, but it might be as well to check that your machine is squeaky clean in this respect, just to be on the safe side.
5 File sharing is a well known vector for the distribution of malicious code and large numbers of machines are infected by this route, the effects can be devastating and sometimes a format and reinstall of the operating system is necessary……For these reasons I recommend that you uninstall all P2P file sharing or similar applications, ( Limewire, ) etc.
6 Malware removal specialists on most forums are now making it a requirement that such programs are uninstalled before further assistance is required.
Regards and good luck
