You can download and scan your computer for free.

Firstly, update Adaware (its a great free utility) and Spybot and run scans. Also run updated virus scans. Once malware risk is eliminated, check your drive, see if its so fragmented that the HDD is always doing extra activity. Clear it of all the junk- run diskcleanup and also uninstall unwanted programs. Then analyze the fragmentation and do as the report suggests. Make sure its not an overheating issue as well.

I'd recommend running the free computer scan at www.freecomputerscan.info. It will scan your registry which is often the cause of many computer problems. It will scan it for free and tell you what is wrong.

the first thing you need to do is clear EVERYTHING that is not neccesary to run the computer. then you need to get a new additional meomry card. after that, get mcaffee virus protection. scan your computer and then it should be ok. if it is not, you may have to completey wip it and reinstall you operating system. if none of those work, take it to a computer specialist and have them do a 'tune up.'

please use "Tune Up Utilities", u can download it for free 30 days trial from www.download.com, or u can buy it.

Then check with "Tune Up Start Up Manager", find which program which load every start up, and u can disable it some program.

Then clean the unneeded files by "Tune Up Disk Clean Up"

then clean the registry by "Tune up registry cleaning'

You can go to the start menu, then "all programs", then "accessories" and "system tools" then click on "disk clean up". Check on the disk you want like disk c. And wait for it to load and then click ok. Or you can go under system tools and click on disk defragment.
