my system just started behaving funny. i lent it to a friend who restored it to a previous date. Once i switch it on it displays the bios screen and then gives this long unending beep before the system sluggishly boots up. even after booting the system just hangs. help!!!!
Check to make sure all sticks of RAM are secure also check all the PCI and PCIE cards to make sure they are seated correctly. It is not uncommon for a computer to have a few parts rattle loose when moving it.
