The RAm suggesstion is a good one. RAM errors are sometimes hard to find. Either the amount of ram, or a bad stick could cause this. I've had RAM sticks that every ram testing program I know said was good, but when I replaced it with another, the computer suddenly behaved it self. Sometimes it's adirty contact on the RAM stick. Try a pencil eraser on it. (works more times than you might think!) I've read of people UPING the ram to 1 Gig to install Win 7, then dropping to BELOW 1 Gig to run. Theysay performance is not that bad. Nice to know.
