Hello all,

I have this Mobo Asus M3A78-EM with an AMD Athlon 5600+ X2

not sure what to do right now... at first the computer would turn off randomly (not reboot but turn off)
so suspected pretty much everything in the book.. first step was to change the PSU. no help there.
then got the mobo out of its case and just tried it solo nothing plugged in ... only ram and CPU (on board video card) still no improvement computer past POST but then shuts down a few seconds later... Tried different ram in different slots.. no success.
did a default BIOS reset (Jumper) nada

removed the CPU fan and cleaned and reapplied thermal paste... no change... the few seconds I have to get to the BIOS when I check temperature all seems fine. (fan running etc)
even tried to not use the onboard graphic and used a Asus Pci-E video card...still same issue.

am I forgetting something ? or this mobo has just gone south ?

thank you very much for your help !!

joeward89, Hi. Most probably it is the motherboard that is failing. Can see any bulging or leaked capacitors?
