[SOLVED] PC will not boot every other time.

A few months ago I built a custom PC. If the PC boots, everything runs fine, and there are no problems.
The thing is that every other time when I boot the PC, the screen will not be recognized. Sometimes I first see the bios bootscreen (sometimes even the windows boot screen), but after a few seconds the monitor is saying: "no video input".
The RGB lighting and fans and stuff is all working, only the video output isn't, so I'm not sure what the problem is here.
If I hold the powerbutton to turn of the PC and reboot again, it boots properly.
This seems to happen every other time.

My specs:
CPU: AMD Ryzen 7 3700X 8-Core Processor
RAM: Corsair DDR4 Vengeance LPX 2x8GB 3200 C16
Motherboard: B450 TOMAHAWK MAX (MS-7C02) (AM4)
Graphics card: NVIDIA GeForce RTX 2060 SUPER
Monitor: AOC Q27G2U/BK (1440p 144hz monitor (DisplayPort) + Philips 24 inch 75hz monitor (HDMI)
Storage: Samsung SSD 860 EVO 1TB (SSD)
Power supply: Gigabyte GP-B700H 700W PSU

Apart from the booting problem, sometimes when it seems to boot correctly, my graphics card is underperforming. When I play a game, I get very low FPS. So I did a PC benchmark test and the graphics card seems to be performing at 35% or something.
So the not booting properly happens every other time, and the underperforming graphics card happened only twice now.

Solved the issue by updating the BIOS to the newest version. Used MSI Live Update 6 to do this.
