Hello all: I appreciate your help. My current system is Windows 2000. My son does a lot of online gaming (he's 12) and this has developed into a multitude of spyware, adware and viruses. I have used spybot, among others to try to remove, and it's not working. I've decided to just wipe the slate clean and upgrade to xp. Here's my issue. First my computer is so slow and my mouse will not work. My upgrade will only upgrade from 98 which I have a disk for. So what I think I want to do is reformat to 98 and then do the install, but I can't figure out how to do this. If I reboot the computer with the 98 in the cd drive it just reboots to 2000, I have checked the start process and it is set to start from the cd drive so I don't know why it is by-passing it unless it has to do with a virus.
