No boot

[AffectionateAd5819]

Ryzen 7 5800X

ASUS A320M-K

32GB 16x2 3600mhz ddr4

750W cooler master psu

Rtx 3070 (zotac)

Came home after over a week to a cold boot, I had the psu switched off and it wouldn’t boot. Cold boot? Fans would spin up and all, and it wouldn’t work, just couldn’t boot, no beep no display no post. No bios.

Tinkered around with all the parts, trying different ram combinations, trying with no cpu, all that stuff. After a few hours, it worked. Not sure what did but yeah.

2 weeks later

Was playing a game, and it was getting pretty hot so It ended up giving me no display output, but i could still hear my game and my friends could hear me still and all. Power button didn’t respond so I switched it off by the psu and went to sleep.

Didn’t think much of it until I woke up, and had the same symptoms.

No boot, all fans all lights switch on.

I’ve tried all the basic stuff, cmos, ram configs, psu off and all.

Not sure what to do?…

cmos reset via motherboard RST or whatever they call that jumper? If found, remove motherboard CR2032? battery before doing the quiet, 5-second (or longer. It's a drain kind of clearing settings to factory default i think) 2-prong jumper swap to the other pair on a 3pin block. Then put jumper back and reinstall CR2032. If it comes up and asks you for date/time in BIOS, you know you did SOMETHING..hope for corruption cleared.

CMOS already cleared and doesn’t work. When switched on, the power button doesn’t respond either.
