I cannot even ctrl+alt+del freezes hard while installing
any avail update have to reset to get working again. also
noted if I leave my pc running for a while with no
shutdown it will freeze up also (approx 15-20 min)have to
reset. but on the update it will freeze in less than 15
seconds...Help Thanks
