Question Should I update my BIOS?

[2Dads]

I've been experiencing freezes while gaming as soon as I started upgrading some parts. I literally tried everything (reinstalling windows and drivers, updating them, stress tests etc.) except updating BIOS because of the lack of knowledge to do so. These are parts that I upgraded:
GPU - nVidia GT 710 to ATI Radeon RX 560 4GB
Storage - 931GB Western Digital WDC WD10EARS-00MVWB0 ATA Device (SATA ) to 480 GB Kingston A400 SSD
Monitor - ASUS VS197 19" to ASUS VA249HE 24"


Event Viewer shows this:

make and model of the psu?
check cpu/gpu temp?

PSU is Antec EarthWatts EA-500D (500W Max.)
CPU/GPU temps are both in 60-75 degrees range, depending of the game except in DotA 2 where CPU goes beyond 80 degrees. Dota 2 and CS GO freeze way more often than other games (PUBG Lite, WoW) where the freeze occurs in 30-40 minutes of gameplay. I don't play many games, just those.
Temps are monitored with MSI Afterburner

how full is the ssd?
malware scan your system?

I bought this SSD 2 days ago because I thought my HDD was causing this problem. (Seatools short drive self test failed). There is over 300 GB of free space on this SSD. Windows and games were installed yesterday.

try redoing the thermal paste on the cpu?

I replaced it 2 months ago, but I'll do it again just to be sure. Thanks.
Do you have any other suggestions besides this? What do you think about that BIOS?

I replaced thermal paste today, but I'm still having this problem.

Another update.. I found a post on AMD community forum that says the following:
"The RX 500 series doesn't work with non UEFI BIOS motherboards. Open the command prompt and type the following. If it says winload.efi, it is UEFI. If it says winload.exe, then it is legacy. "

Mine says it's winload.exe, so it's legacy. Could this be causing this problem or the PC just wouldn't boot if this was an issue? Do I have to buy a new motherboard or is there some workaround?
