My Acer Aspire M1100 will not boot.It powers on, and the fans and everything run, but I get no signal on my monitor (so no BIOS screen) and I don't hear the 'beep'. I've tried opening the case and using canned air to blow out dust, as well as disconnect and reconnect connections as far as the fan, memory, network card, etc. I've had this computer since 2008, and there were 2 years when I didn't use it at all. The hard drive recently died, so I don't know what else to do at this point.
