Question about Acer Aspire m5640 PC Desktop
Try to make a "clear CMOS". There should be a 3 pin slot on the motherboard. Remove the jumper from the first 2 pins and put it to the other 2. The middle pin will be always occupied.
If not, try to change the power source and see if it does the same thing. If so, then you have to change the motherboard.
If you need further assistance, just leave a comment.
