Might be time to a clean install from OEM disks. I guess you could try to figure out if it is hardware or software too. Might see bios if you have health settings. Might try safe mode boot to see if you can see what event logs say. Dunno which way to start really. Playing to the angels Les Paul (1915-2009)
