i had gone through the 8 steps for virus removal and then some, but my pc is still running slow. everything from boot time, open/close programs and loading a web page is slower. pc is free of virus and malware. this is the link to the thread that verifies virus/malware removal. http://www.techspot.com/vb/topic141626.html i have ran CHKDSK. HD is ok. Ran 4 simultaneous Memtest at 727MB each checking 550%+ of RAM. RAM is ok. i was also told to run the xp repair tool to try to repair any corrupt files, but i cant find my disk. i did however register my software with microsoft. is there anyway that i might be able to download a repair tool to a disk or is there any other alternative to fix possible corrupt system files? what else might cause a pc to run slow?
