PC not powering

Yo, correct location for thread??

Shut down PC, went away for 4 days/3 nights, came back, when to boot up, all started showing signs of life, then not even 2 seconds, all turned off again. I forgot to flip the switch off on the PSU before I left, so I don't know if this has affected something. I think it could be the Motherboard, but see no burn marks, and I don't believe it could be the PSU. Could it have anything to do with the CMOS battery?

AMD FX-8350
Noctua nh-d15
Asus Crosshair V formula Z
Corsair 12 gb RAM
Leadex 1200W 80plus platinum
msi GTX gaming x 1080
2x 3tb wd black
240gb ssd
128gb ssd

I'm thinking that it's either a cpu cooler or power supply issue which would be a shame cuz your psu is a beast.

Is your cooler working okay?

My cooler was working fine.

I tried boot with cpu,cooler,psu and mobo,same. Think I should try with JUST mobo and psu?

I think you need to test with a new CMOS battery. Your system is quite a few years old, isn't it? And 5 years is the expected lifespan of the CMOS battery.

I took it out for 5 minutes,and tried again,nothing, ill just test mobo and psu for now till i get something of a decent result, at least a new battery wont be too expensive

got some help from a friend, jump started psu, and that appears to be the problem, and should be within warranty still (5 years)

Yea,hopefully I can get it all sorted and get it working, it is kinda hard as I am in the middle of packing to move.
