It's my boss's home computer which he brought into the office for me to look at. PC is 800, P4 with 15 GB hard drive and 12 free space. It takes about 15 minutes to boot to the logon screen, then another 15 minutes to load the desktop. Once it's finished loading, programs respond okay...perhaps an occasional lag. He keeps it running all the time because of the boot up problem. He says he defragged yesterday.
He had a worm which I removed....I did a virus check and it's clean.
I windows updated Service Pack 4 and the security patches. Boot up is still horribly slow - really 30 minutes or more. Can anyone provide a cure or an explanation as to why he's having this problem?
