PC Randomly doesn't post after shutdown

[almond_farisa]

 Having strange issues suddenly. Recently installed a 4090 as described in my specs below.

Pc is performing in games as expected and no issues such as freezes,bsods restarts or anything of that nature.

But I am all of a sudden getting random no display no posts, its been almost two weeks since I installed the card and pc was definitely not doing this before hand.

I have also used the new corsair 600W PCIe 5.0 12VHPWR Type-4 PSU Power Cable to connect the gpu.

Seems to post after restart not so much if it's shutdown but posts after a hard reset/shutdown from the no/post no display state.

This happened once before but today seems happen nearly every time the computer is started up after being shutdown via the windows start menu.

So long story short, I have a hunch that you are having the same issue alot of 4090's will start to have, take a look at this video for a better example than I could ever type out.

I don't have a working phone at the moment to take any pictures. But i'll get some tomorow and upload them. I'll show the cable setup but there doesn't seem to be any melting I can notice around the cables or aggressive bending of them. Again i'm using the new corsair 600W PCIe 5.0 12VHPWR Type-4 PSU Power Cable 

In the meantime i'll see about grabbing one of those cables jay recommends at the start of the video

I think i found the solution, I checked windows reliability monitor and the initial no post was listed as windows hard disk failed or something like that. So i ran checkdisk and after 45-30 minutes on each drive now starts and shutsdown properly. So far so good. I won't mark it as solved just yet.

I love your case.. i have it in black   altho somewhat more aging equipment in it. as i transplanted my old fractal define R6 into it(but it's heavy as **** :D). 

 

back to your problem, yes that sounds like a valid solution, check that none of the connectors came loose if they are external ssd's during the swap on both side, so PSU too.

yeah no more black screens on post after running chkdsk...
