Hi everyone, I hope you are all doing well. Or at least, better than I am.

I have just built my PC today. it is:

Ryzen 7 5800X
MSI X570 Tomahawk WiFi
Nvidia RTX 3060 Ti
32gb 8Pack DDR4 RAM
Seasonic Focus PX-750

I haven't once managed to get it to connect to two different monitors on DisplayPort or HDMI on GPU or HDMI on the Mobo.

What I have tried:
Stuck the latest stable BIOS for the mobo on a USB drive, renamed the file to MSI.ROM and stuck it in the flash USB port on the mobo. I powered up the PSU and pressed the flash button. It did its own thing, cycled through, running all fans and everything. It ran, powered down for a couple of seconds and powered up again. I left it a few minutes and the USB stick wasn't flashing anymore, everything was quiet. I waited an extra 5 minutes or so and then powered down via the PSU.

I have powered the PC up again and the monitor hasn't reacted at all, so no display output on PC. The mobo debug "Boot" LED is on constantly.

Any advice? Should I just try and stick the Windows 10 USB in and see what happens?
 
Some progress. I have a BIOS screen.

I powered down the PC, loosened the CPU cooler a little (BQ Dark Rock Slim). It would have tightened forever so I wondered when to stop.

I also switched the monitor from mobo HDMI to GPU HDMI. Powered on and like I say, there's a BIOS screen
 
Did you tighten with fingers?
CPU cooler? No, screwdriver. I didn't go mega overboard I just noticed it would keep going and the bridging arms would bend. Although I held back it looks there was more scope to further hold back..

Installing Windows 10 now.
 
Up and running now. Windows installed really quick.

Looks like I am sorted. Mods please feel free to delete this thread.
 
Good to hear you got this sorted.

As that CPU + mobo has no onboard graphics, switching HDMI to the GPU will probably be why it now works. :)

Ah that makes so much sense. What a numpty I am. It being my first build I had been over thinking and assumed the mobo would be the first thing to connect to.
Turns out there's not really much more to it than flashing BIOS and installing OS.
I was really expecting a nightmare but it worked out well. My UserBenchmark scores are impressive and everything about the pc is rapid - installs, boot times, running games. I love it.
I expected to regret the 3060 Ti but it is really good.
 
I don't know much about mobos but the X570 Tomahawk has WiFi and was really easy to set up. It was also incredibly easy to change xmp profile for my RAM
 
Ah i had renamed mine to MSI.ROM. Mine flashed for 5 mins then stopped but didn’t power cycle - is it done or? :(

Mine did the power cycle. Are you doing it exactly like he's doing in the video?
Which BIOS are you using? At the time of flashing, the latest was a beta so I used the version prior. Haven't done it since.
 
Yeah that sounds like it did the job. Maybe it didn't like something about the first USB - formatting or whatever. Hopefully that is you sorted now. It was easy enough to switch XMP profiles in the BIOS but that's about all I did with the mobo.
