I have windows xp & last night my cursor froze up. I replaced the mouse but that made no difference. I used the keyboard to navigate & did a system restore to 2 days previous. That did nothing. I powered down several times & still no results. I was playing spider solitaire that came with the computer when the cursor froze. This morning when I turned the computer back on the cursor was working again, but when I started playing spider again it froze up after a while. I powered down & got the cursor back, but who knows for how long. Could the spider game be causing this? I'm running my virus scan right now & so far no threats. Please advise.
