PC Wont Start Up - Fans Running, No Display/Power to Keyboard/ Mouse

Hello, so, last night my PSU Fan died on me, thus had me following that by shutting of the PC and switching out the PSU to a new one. i know the PSU works, because i tested it in another computer before switching.

the Motherboard is a Asus F1A55M CSM
4 GB DDR3 RAM
450 Watt CodeGen PSU
and the cpu is a AMD A-4 3400 APU

The MB battery is good, i tested it in another computer

Any answer would be good. I hope i dont need a new MB or CPU.

Also, ive tested it even using HDMI on another monitor, i mainly use VGA though.

AND the motherboard Power light turns on green.

HELP PLEASE!

Just a guess but is the cable that goes into cpu plugged in?

That would be the square 4-pin right? if so, than yes, and the 24-pin is also connected

Yes the one at the top...(usually)....hmm can you test your cpu somewhere? If i was you I would test each component bit by bit which will allow you to figure out what's wrong

did you by any chance reset bios settings? I had the same thing happening to me when i added another hdd into my pc and I had to change the mode...in bios...just try to reset bios and see if that helps...other then that I have no clue what it could be but im sure once you test it you will see what's wrong

unfortunately the other systems here are Intel's and laptops. and no i didnt reset settings. not sure how i could do that without a display unless theres a way to do a hard reset from the outside
