I have a XW6400 workstation, a week ago my computer was working properly and okay then i tried using it the other day and this happen. after the monitor goes to sleep i can still hear the usual sound of the Windows start up and after that a 2 beep sound from the CPU. oh btw, im using a 2 monitor set-up.
I went to HP support and they say the CPU is functioning okay and even tested it before i leave but after i came back, im still stock with this problem.
Really need help on this... Thank you
