[SOLVED] No BIOS start up screen, can't get into BIOS. Boots into Windows fine

[samthemancpfc]

Hi guys, so i just upgraded my MoBo and CPU to a Ryzen 7 5800x and MSI MAG x570 Tomahawk WiFi and first boot went comepletely fine, booted up i went straight in to the BIOS to turn A-XMP on and look at other settings. I turned on "Gaming Mode" just to see what would happen, had a few issues after that but got them sorted and since then I don't see the BIOS Boot screen, whenever i spam DELETE it just appears blank on all 3 monitors, and I can't figure out why. if I just leave it when I restart or power on it will boot into windows without any issues.

So i have tried resetting the BIOS both by holding a coin on the JBAT and also removing the battery for 10 seconds. I hgave also tried to switch monitor, unplug 2 monitors just so one is connected and the same outcome. Also Windows Fast boot is also off, and I have tried to go through advanced restart and UEFI settings through Windows 10.

Here is a video of what happens.


EDIT: Took my CPU out and placed it back in again, it works from there.

This all has to do with security btw win10 and Motherboard,
you may have better luck at MSI website - https://www.msi.com/search/MSI MAG x570 Tomahawk WiFi no Bios/support/faq
Things i have done with my Asus, the last one I hate
Boot from win 10 dvd - repair boot info
Press reset cmos button on MB - clear cmos
Shut down windows 3 times during startup - windows repair screen

I've tried to clear CMOS a few times, nothing changes at all.

I had a similar issue with a laptop.
The answer was to get windows to completely shut down.
Likely your cpu removal did that.
The easy way was to hold down the shift key while hitting the shut down tab.

A more convoluted way is to get into windows settings and recovery mode.
The details, I forget.
