Please Help Computer Very Sick

Needing help!……My computer randomly has windows pop open that are from the operating system, like start menu, desktop property and the mouse cursor frequently will randomly fly around the screen and open additional windows or lock up for 20 seconds then start working again. Keystrokes will also lock up then start working again. Sometimes when the cursor stops working the system freezes up permanently until hard reboot.

I have restored system many times, then erase/reformatted hard drive still did not fix problem, then used a program that as I understand zero fills or xo fills every space on the hard to help ensure no trace of anything can be left over still did not fix the problem. When I reformat etc it seems to slow down the frequency of this problem but soon its right back to its tricks several times within a ½ hours timeframe.

Any ideas????? I’m feeling like I may have to buy a new hard drive.

My log file include chatwatch, guardian monitor and besafe. I purchased all theses about 1 year ago to keep tabs on our teenager. They’ve never caused me a problem. I use AVG, Spysweeper, Spybot search and destroy and Adaware.

I can not do an online Trend Micro House call scan. I can not fully get XP updates/patches and I tried to download trial of spydoctor to see if it could find anything extra and it will not let me run the application it opens then sits frozen
