Hi,

I just bought a new PC with the following things:

ASRock B450M-HLD R4.0 (BIOS P1.0)
RYZEN 5 2400G 3.9GHz + Radeon Vega 11 AM4 STOCK Cooler
(stock settings, XLP profile for RAM, and 2gb allocated graphics memory)
2x8GB RAM Team DDR4 2666MHz T-Force Vulcan Red
Power Supply Corsair 450W CX450M Semi Modular 80 Plus Bronze
SSD Kingston A400 240gb 2,5'' Sata3
HHD Seagate 1TB Barracuda 64MB SATA 6GB/s

and also I already had a wifi card
TPLINK PCI Express Dual band AC AC1300 - Archer T6E

The problem only happends during games
I just tested the following games
GTA V
CS GO
The division 2

the system just Bricks. It shows black screen and I can't do nothing to restart the system. If I press and hold the power button, nothing happends, I also tried to press ctrl + win + shift + B to reset graphics drives but it doesn't work (I have the last recommended drives). The PC keep working but it shows black screen.

I have reinstalled windows 10 3 times and I tested it with different drives for the APU, I pulled off the wifi card and I change the SSD with other I have but it keeps doing the same.

So, I believe that you are going to recommend me to update the BIOS because the asrock web had a lot of BIOS updates
https://asrock.com/MB/AMD/B450M-HDV R4.0/index.es.asp#BIOS

so I would like and advise before upgrading the BIOS,
What should I do to prevent a fail during the BIOS upgrading?

And also the asrock webpage says that I need to upgrade to 1.4 before upgrade o the last version 2.3
and other thing that I don't understand is Why the page says that I need to install the VGA driver before upgrading the BIOS?

Thanks.
Leonardo.
