The system tried to start up but could not I opened the tower and toke the memory’s chips out then Put them back Then I tried booting up again. It gave the message PREVIOUS ATTEMPS AT BOOTING THIS SYSTEM HAVE FALIED AT CHEAKPOINT (VCLS)(just that not all that is in the top part of this) then is stuttered into life. Has anyone a clue coz I don’t.
