OK, I have this old Acer Aspire M5100. Last time, before putting it in the closet, I used it half a year or so ago it was OK. Today I took it out, but there's nothing on the screen and there's no beep sound. Actually, to be hones I don't even remember whether it was beeping by then, although I can see the speaker on the board. I do't know whether the beep speaker is faulty.
Here's what I ruled out so far. Booted without anything at all, booted with the CPU and just 1 RAM installed, no beep and nothing on the screen. Monitor and PSU work OK on another system. Booted it out of the case, still the same thing. The same thing with on board and attached video cards. Changed CMOS battery too. Please help.
