Answers :

\015\012This could be caused by a lot of different things.

\015\0121. The first thing I recommend you check is if the computer is overheating. Check all your air vents for dust buildup. Use an old toothbrush to brush the dust away from the vent holes and blow air through the vents using one of those compressed air cans made for cleaning keyboards. One time I worked on a Sony laptop that I had to take apart to get all the dust cleaned out of the air vent.
If you think overheating is a problem I recommend downloading a free piece of software named FanSpeed. Here's a link.
http://www.softpedia.com/get/System/System-Info/SpeedFan.shtml I'll let you read the description for yourself, but in short it allows you to monitor the temperature inside your computer and to adjust how the fans react to this temperature.

\015\0122. The second thing I recommend you do is to turn off most of the programs that get started up when you boot your computer. Most of these programs aren't doing anything except using up system resources. I'd leave you virus scanning software running but turn everything else off. I'm assuming you're using windows XP. Hit start then run. Type msconfig in the popup box and hit ok. The system configuration utility will come up. Hit the startup tab in the upper right. You will get a list of the programs that are started up when you boot the computer. Just un-check the programs you want to remove from the list. This doesn't delete any programs; it just prevents them from being started automatically. You can still start them manually or you can go back to the list and re-check the boxes of the programs you want to add back in. You will need to re-boot your computer to make these changes. On the first re-boot a notification box will appear telling you that you've modified the startup configuration. Just check the box in the lower left corner to tell the computer you don't want to see this notification again. A side benefit of removing all of these programs at startup is your computer will now boot faster.
\015\0123. The third thing I recommend you do is to make sure you have all of the latest Windows updates from Microsoft.
\015\0124. Next I recommend running a defrag on your hard drive. It may not let you run a defrag until you run chkdsk or scandisk to fix any error on your disk first.
\015\0125. I also recommend you run some registry cleaning software. There are several free register cleaning downloads available at download.com. This is a safe site. It's associated with Cnet.com. They have lots of good, safe, downloads.
\015\012I hope this advice helps you out.
The most likely thing is that there is a virus of some sort on your computer.  If you have the restore cds that came with it you are going to want to restore the computer earasing all data from the hard drive.  This should make your computer the way it was when you first bought it.
