Comp messed up

Does anyone know what’s wrong with my comp?!? I can’t figure it out!

I originally had Windows XP Home on my comp, then it restarted for no reason. Every time I logged in, like 5 mins later it would restart.

So I re-image, right? I put on 2 partitions of Windows ME and 2000.

Windows ME works great, but 2000 still restarts. Whats almost as bad, I can’t see the tree when I explore.

Can someone plz help me?:d:
