Question PC wont post and USB ports doesnt work

[jarmo99]

Hi! I switched gpu from 6600xt to 3080 suprim x. I uninstalled amd drivers and switched my components to another case. Now when i try to boot my pc there is no signal because i can't move my mouse or keyboard because usb ports doesnt work. There is no error lights on mobo but i have two sticks of hyperx fury ram and other one is completely off and other one is blinking red led. Weird thing is that i was able to update bios trough bios usb port and i can charge my phone with usb ports. I have already tried another psu, clearing cmos boot without gpu, boot without ram sticks and one stick at time. and tried to build whole pc twice. nothing seems to help.
My build
I9 10900K 1.28V 5.1ghz pretested
Asus rog strix z490-f gaming
Kraken x63
Msi suprim x 3080 10gb
16gb DDR4 hyperx
Seasonic GX 850W
corsair 4000d airflow

Please give any tips you have!

This is just a hypothesis idea but what if the ports are either not compatible with the sticks after the update or their not imported well enough in the mobo. I've actually had this problem last night where a freshly formatted USB wasn't being recognized by my system; all I had to do was dust it out or try it again after a wiggle and worked. Also, power should be adjusted as well as 850W is best for those specs but better to be safe than sorry and stick to 1K for reasons.......................................

Hmm 850W should be enough for a build like this, maybe the mobo is broken unfortunately.
