As of today I have a machine that will not boot. The power light comes on, the fan spins but it quickly starts beeping. The beep is continuous. I took the memory out and put it in another machine and that machine booted fine. So I don't think it is the memory. Everything else I am reading says it may be the power supply. If the lights come on and the fan spins would it be the power supply? The machine is an Acer. I would appreciate any help.
