Also AIO fans not working. I'm pretty sure everythings connected. Do i need to download bios onto a usb and insert it then try booting?

CPU: Amd Ryzen 7 9800x3d Motherboard: Rog Strix x870e

Please help!

Hey, all -- would appreciate any thoughts on this. Been using the same machine I built in college for about a decade now, with a GPU midlife upgrade but otherwise without any big changes or problems. While web-browsing two days ago, suddenly it wouldn't connect to USB and then seconds later unexpectedly powered off. Upon trying to restart, my Asus motherboard starting flashing a 00 code. Briefly, the monitors continued to work, but now they won't connect, either.

I did some googling and already tried clearing the CMOS by pulling out the battery, to no effect. Also tried getting into the bios by pressing the function keys (and delete) while restarting, and that hasn't worked. I can't figure how to get into the BIOS at all, and without the monitors working, I'm at a loss. I'm hoping there's something dumb I'm missing! Would be grateful for any help.

Here's a quick link of the internals -- my cable management is not great but looks worse than usual in this... https://imgur.com/a/9YE5NMS

Hello, For nearly a year I've been receiving error code "00" on my Asus motherboard. No POST happens a lot of times but after turning it off and on for a couple of times(Sometimes just leaving it off for a few hours and then turning it on again) it will again continue to work normally. During the time when "No POST" happens, I've tried removing RAM sticks and I received the same code.

I've also taken my computer twice to the repair shop. These people did the same thing I did. They checked with different RAM (Same Code-00), then they changed the PSU (Same Code-00). And then they say its a motherboard problem and they need to mess with ICs else my computer won't turn on. Another person said my motherboard is dead and I should buy a new mobo instead.

I usually just take the PC back because I know that if I leave it off for a few hours, it ends up working fine(Most of the time it turns on with just a few attempts).

May I know what should I do to fix the 00 error so my computer works fine always?

Things I have tried:

Resetting the BIOS. Works for a day and then it goes back to Code-00 and after 4-5 attempts of powering On and Off it works fine.

Leaving the system on for 10 or so minutes and then retrying (It works most of the time this way). Saw this on a youtube comment once since a lot of people seem to be getting this 00 error. The explanation which the user gave was that the processor needs a bit of warmth. (But again sometimes it doesn't work).

Clearing CMOS and Removing the Battery (This worked the first time I faced the 00 Error. It worked for a few months and when Error-00 appeared again, I tried this method but it didn't work)

Keep in mind, when my computer works it works perfectly. I even tried doing the stress test on CPU-Z and it worked fine. Could it be some major problem still?

Hello. A few days ago I was replacing thermal paste and reinstalling windows on my old pc before selling it. After that, everything was fine, but later when I turned it on again, blue screen appeared after a few minutes and then nothing showed up anymore, computer is turning on, fans are spinning but nothing appears on the screen. My motherboard shows error 00. I made sure that everything is plugged correctly into motherboard.
Things I've already tried:
removing and changing ram, changing slots
taking out and replacing cmos battery and using cmos reset jumper
unplugging gpu, ssd, air cooler
