Hello, I'm not sure where to post this question, sorry Mods.

My sons computer (Win ME) is having lots of failures when its starting up, it gets to the desktop but nothing loads on the desktop and it freezes. This is intermittent.

We deleted all the internet files and cookies and history. We ran Spybot and found nothing. When we run a Norton 2005 scan that includes the C:/WINDOWS/SYSTEM folder, the scan stops after scanning 25 files (not including running programs). This is in the system folder. It is always a different file that it stops on. We ran scan disk and defragged. We also uninstalled and reinstalled Norton, no change.

We replaced the hard drive about a year ago so its fairly new.
Can any one clue us in as what we can do to remedy this?
