Question Acer Nitro N50-620 - I can't access BIOS

PC: Acer Nitro N50-620
Hardware: i5-1140f, RTX 3060 12GB, 16GB RAM.
Windows 10 64bit.
No matter what I do, I can't access BIOS. I already did reset CMOS, then swapped CMOS battery. Neither F2 nor DEL or F10 work, I even tried to use Restore option with UEFI boot and nothing. It doesn't work, my PC restarts and boots me up to login screen. I also have no "welcoming logo" (as it should be Acer's welcoming screen), PC just starts and immediately shows the login screen even though I have disabled the fast startup. It has been like that since I got this PC. My BIOS version is R01-A2 and what's even worse, not even Acer's official site has this version of bios ready to be downloaded. I tried installing BIOS from their site, both A1, A3 and A4 and still nothing - my PC turns off for few seconds, sometimes even turns itself off and on few times, then turns on and I am back to the login screen. Can it be hardware's issue like faulty RAM or GPU? I already asked on Acer's forums but no real responses there. People just told me to do what I have already done and what I described in this post. Please, I am really getting desperate.
Yes, I regret getting a prebuilt PC but I am still trying to make it work.

EDIT: And if there will be diagnosis of a faulty mobo, could anyone recommend a good one for my LGA 1200 CPU along with the case for additional cooling? Thank you so much for any help.

FIX: If you are using GPU like RTX 3060, which maybe isn't top tier but is "new", don't use old display monitor like Samsung SyncMaster with DVI port that forces you to swap to DVI/HDMI cable to make it work. Turns out, if you are booting system in safe mode or try to access BIOS, GPU/display drivers are preloaded and GPU doesn't work with new monitor. In my case swapping from old SyncMaster with DVI port to LG 24MP60G-B with native HDMI slot solved the issue. Now I can see POST, BIOS and everything else.
So thank you everyone for help, but problem is now solved. Please keep this thread so people who struggle with same issue might find a fix. Have a great day everyone!

Sadly, no reaction at all whether I unplugged each RAM separately, both SSD, one SSD. Nothing happens at all so I guess it might be just faulty mobo.

Advanced startup option? Even with fast startup off, Windows 10 and 11 is pretty aggressive in finishing POST.

I just tried. Now my PC won't turn on at all. There is a single beep and screen stays black. Nothing except I can’t even use my PC now.

Wait, so you were using adapters on it? I see.

Most GPUs abandoned active signal conversion for older display protocol that make any passive adapters very flaky. Active DVI to HDMI adapter might be needed for that old monitor if you haven't do that already, but really the future is just to abandon the monitor entirely.

Precisely, I had a monitor that had only one DVI port, nothing else, so I was forced to use DVI to HDMI cable. It wasn't really a standalone adapter, it was a cable with DVI on one side and HDMI on the other. As you say, newer GPUs just abandoned conversion so my Windows worked only in normal mode. Anyhow, problem is now solved as I have an LG monitor with DVI, HDMI and displayport.
