No POST

[Skullbiter]

Guys I’m in dire straits! 

specs as follows:

i7 8700

ROG Strix. B360G

gtx 1080

2x8gb Corsair vengeance lpx 2133mhz ddr4

corsair RM550x PSU 

 

mobo lights up but no POST after turning the PSU on. There may have been a slight flash.

 

what I have tried: swapping out RAM

disconnecting GPU

reseating connectors on mobo 

investigated for odd smells or any funny caps

 

I’m not sure it’s the PSU since the mobo lights up, I can’t see anything wrong with it.. what else could it be?? My CPU? Coz that’s not something I can easily fix going on national lockdown from tomorrow 12pm 

 

RAM seems fine. Mobo seems fine. GPU doesn’t appear to be the issue. Not sure how to eliminate the hard drives but it would post I think even if the hard drives were doing something funny. HALP!!! I need my pc to work or I’ll die of boredom!

Any Post Codes? Try clearing out cmos is that doesn't work try switching cmos battery

The mobo is literally a month old... but ok

My apologies. I tried it anyway and no dice.

 

so would it be possible for the PSU to be broken but still light up the mobo? I’m suspecting the PSU, everything else looks OK

Tried another PSU, no dice. Does this mean my CPU is dead?

Try reinstalling the RAM a few times. I've had it happen on my board where I had to reinstall the RAM 3 times because the slots were being picky. You could also try reinstalling the CPU.

 

Did you clear the CMOS?

I did change the CMOS battery but I don’t think it was that, it appears it was in fact the PSU. 
 

tested the old PSU by bridging it out and it wouldn’t even start. Luckily it’s got a warranty so I’ll get it replaced..... eventually. 3 week lockdown ahead so fortunately I’m not without a PC. Couldn’t have picked a better day to happen either

Yes, it did... but now I’ve got another seemingly unrelated problem

What's the new problem?

I made a new topic, since it’s probably unrelated and has it’s own set of symptoms
