4CFED, Im more of a hands on person when it comes to computers, so im not good at walking through the procedures. You can do a "disk defragmenter" when compresses old files and frees up space on your drives. Another thing i noticed on mine was slowness starting occuring cause i was ate up with spyware. Adaware, adaware.com (i think) has the free download it removes spyware, cookies, and other files that run in the background, therefore eating up CPU usage. Another quick fix is clearing your browser. (under internet options and deleting history) this stuff builds up and the PC ciphers through it every time you use the net. Are you using a HP? They are notorious for this problem. I got three with the same problem you speak of. Also go to control panel and delete some of the BS that you dont use. Myspace IM, Yahoo IM, Limewire, Kazaa, etc.Are notorious for bogging a PC. Because they continue to run off and on in the background even if your logged out. Im not an expert but PM if you want a specific on anything i mentioned. Alot of good info on the net too, google it up... Good Luck..
