Recently I upgraded to an MSI FM2-A55M-E33 mainboard (computer specs are below). The computer typically enters a sleep cycle about an hour after last use. However, the last time it did this it would not power back on. I tried the following:
Changed the power chord, changed what outlet it was plugged into
Changed the power supply to a known working unit
Switched to a different power button
Moved the ram to a different slot
Removed the CMOS battery and replaced after about 30 seconds (Is it still called that with a uefi? I'm not experienced with uefi)
All of these yeilded no change. The computer does nothing when the power button is pressed. No fan movement, no beeps, no lights.
MB: MSI FM2-A55M-E33
Ram: 1 stick ADATA 4 gb 1333 DDR3
HDD: 1 Sandisk 64 GB SSD, 1 Hitachi 1 TB HD
CD/DVD 1 HP super-multi drive w/ lightscribe (This is a new addition)
CPU: AMD A8
GPU: nvidia geforce 9600 GSO (This is really old)
Any help is greatly appreciated, I'm pretty stumped by this!
