Aspire M7720 blinks power once, not turning on
I have a Aspire M7720 using for 5 years and no hardware changes. I usually turn on my computer and leave it overnight. I have an additional USB fan plugged in.
I was using the computer just now when suddenly it turned off by itself. I waited for 5 minutes (because my computer will fail to startup during Windows logon screen and stuck). After 5 minutes, I tried to on it and nothing happens. So I switched off the power supply and waited for another 5 minutes and on again. This time, the power light (cylinder thingy) blink once and nothing happens.
My LAN cable was plugged in and flashing all the time, so I supposed it is working.
My USB fan was also working when the computer was switched off and power supply was on.
I could not know what problems do I have, but I knew the AC Plug was working.
Can it be the motherboard? Hope I gave enough details. Thank you.
