That shouldn't be the problem, I've used a couple mice before that were P/S2 with an adapter. Plus, the first time I started the computer, the new mouse was working.
Haven't tried booting in safe mode, but not real comfotable messing with that yet. I just built my first new computer, and I'm more familiar with it than this 4 year old model I'm having problems with. I'm trying to set it up for my parents to use to surf the net.
I actually think I'm going to reformat the drive and start fresh unless I can find an easy solution. Nothing is on it that I'm that worried about losing. I just want it to be trouble free for my parents.
What should happen if I reboot in "safe mode". Can I do that with an older computer? I've only browsed through the Bios on this board once. Is that where you choose to boot in safe mode?

I'm still learning the basics........

Thanks
