hi guys...i'm having computer problems again. It started with my mouse lagging when I would click on stuff. It would freeze up for a few seconds when I tried to click on stuff or just freeze completely but only my mouse my keyboard still worked. I even bought a new mouse but it still does the same problems. My computer recently just started restarting by itself. I get this error message saying Cmos / gpnv checksum bad error and it would startup sometimes now after i get the cmos error my computer just freezes with black and white lines. Any suggestions or help? Thanks
