|4ever, there can be a number of reasons for slowness. Probably the most common is lack of sufficient memory. That can have several causes. Could it be your firewall? Some are overzealous. First thing I'd look at after that is actual installed memory. Essentially, there's no such thing as 'too much', the more the merrier. Anything less than ~500MB and you probably need more. There's not an iron clad rule.|
Next is some sort of nasty. I'd run a scan capable of finding/fixing a worm/trojan as well as a virus.
Next is trying to start too many things. Software writers seem to think there's no possible way we could get along without their latest and put it in the startup menu when simply having it in 'programs' would do. Can you pare it?
Next is a file called 'index.dat'. A common ailment is a file called 'index.dat'. It gets read every time and can take quite a while if it’s too bloated. It's like a log file and keeps a record of every site you visit on the web. Empty, it's 32K, but it can grow HUGE. It's a protected file and can't be deleted by normal methods. CCleaner (free @: http://www.ccleaner.com/) can get rid of it when it’s ticked (not to worry, it gets rebuilt EMPTY on the next boot.). May not be your deal at all, but won’t cause any harm to try. There're others, but these are the most common I've run into.
