My PC started doing this thing where it will post normally when powered on, but wont show display after the bios screen. I restarted my pc with the power button 6 times and I got it to turn on normally. Usually following restarts work fine, until the next day or so and then it happens again. Usually when it powers on correctly, the windows spinning wheel stutters couple times.

I tried reinstalling windows, updating bios to the latest version and researting gpu and ram, but no luck.

Latest hardware change I've done before this started happening is swap out rx 5700xt for a used rx 6800

My 6800 is undervolted to 945 mV 2280 MHz and it works fine when gaming.

What could be the issue?

Specs.
Rx 6800
5800x
Aorus i 570x pro wifi
Corsair rm750x bronze
32gb ddr4

I'd try removing the GPU undervolt and see what happens. If the system fails to boot normally, disable XMP on a temporary basis. It's one less thing to worry about. Do you have Windows Fast Startup enabled. If so, disable it for the time being. It might be loading a corrupt configuration from hiberfil.sys. These are all guesses on my part. Set everything back to stock in the BIOS.

My guess is it's detecting hardware (problems?) and searching for a driver. If you haven't been able to shut down Windows cleanly, the "dirty bit" might be set on the drives, requiring a disk check. It could be something else.

I removed the undervolt. I actually disabled fast startup couple days ago and since then the problem started. Restarting computer works fine but completely shutting down the system and starting it back up causes the issue some times.

EDIT: I tried enabling fast startup again and the wheel stuttering disappeared and windows booted normally. Can't really say for sure if the problem has disappeared though.

I don't understand the second sentence. The problem started after you disabled fast startup a couple of days ago? And now that you re-enabled it the problem is no longer happening?

Disabling/enabling fast startup is a good way to diagnose a problem but it's not a fix. If a computer boots normally with fast startup and doesn't without it or vice-versa, it means that something is wrong. For example, fast startup keeps some hardware powered on when you shut down the computer, so the fact that it doesn't boot when it's disabled could mean that you have power issues.

Hi,

Well I noticed the problem after disabling fast startup, the computer had never refused to start up like that before. Even with fast boot enabled, the startup today wasn't perfect. It flickered and stuttered a bit, but at least the computer turned on.
How should I go on about diagnosing this?

Fast startup / fast boot......are you talking about the bios option or the windows option?
