I have a weird issue, i got a new GPU (Gigabyte GeForce RTX 3080). Everything works just fine, but when i boot the PC, i get a "no vga detected"-alert.

The thing is: Other than that alert, everything works perfectly fine. I get a signal from the DP port, Windows boots and it, as well as games run without issue.

I already did a bios update. Interestingly after the update, i did not get the alert, until i re-enabled CSM. (Boot device is an NVME-SSD (Samsung 970 EVO)) in Slot 2.

It's not that annoying, only:Is it something i should be worried about?

Thanks everyone for your help, but i'm an idiot and misinterpreted the beep code. (After the normal beep, it's 4 short beeps, not a continuous beep and 3 shorts).

Seems to be normal with 3080 and 3090 when booting in Legacy mode:

It doesn't seem to be a further cause for worry, though so i guess i have to live with it until i reinstall Windows in UEFI mode.

My config, FWIW:
MB: Asus MAXIMUS XI HERO
CPU: Intel Core i7-9700K 3600
RAM: D416GB 3000-16-18-18
PSU be quiet! POWERZONE 850W ATX23
Boot: Samsung SSD 970 Evo 1B M.2 NVME
