Prime Z790 Wifi, freezes and crashes after Bios Update

Level 7

 I updated a bunch of drivers and the bios (not sure from what, it had been a while) and am now experiencing crashes and freezes on a crazy level, like between 2 seconds and 10 minutes a crash or freeze 100% of the time.
Sometimes it even freezes within the BIOS menu which makes me think its not a Win driver issue?
I've unplugged everything and switched to a different wired keyboard, I've removed the RAM sticks and alternated trying them one at a time in different slots, Ive tried rolling back the BIOS to various versions, it often hangs on boot and has all sorts of issues starting up, but does get into Win after a reboot or so

13th Gen Intel(R) Core(TM) i7-13700K 3.40 GHz

GIGABYTE Gaming GeForce RTX 4090 24GB
WB Black SN850X 2000GB
G.Skill Trident Z5 32GB (2 x 16GB) 288-Pin SDRAM DDR5 6000 CL36-36-36-96
Corsair HX1000i
DeepCool Liquid Cooler LS520

the only issue I had before this update was I couldn't run the RAM in XMP, it would eventually crash but I just turned it off and let it clock down a bit and forgot about it and it was 100% stable from there.
I've tried looking in the event logs but it doesn't tell me much, my gut says its about the RAM or the mobo itself but at this point nothing is off the table
Any idea's about hunting down this gremlin? 

Many Thanks!!!

Freezing within the BIOS certainly indicates there is a problem somewhere. 

1. Clear the CMOS using the instructions outlined in the user manual 

2. Reseat the CPU whilst checking the pin pad for any debris or bent pins, then remount both CPU and cooler whilst ensuring consistent mounting pressure.

3. Check both DIMMs are fully inserted into slots A2 and B2

4. Leave BIOS at optimised defaults and run a memory stress tool such as Karhu RAM Test or TM5 from the operating system and check for errors.

Hello, @FlacoGuapo 

Please refer to the relevant instructions provided by @Silent_Scone for troubleshooting, and if necessary, consider the test with minimal components for isolating the possible cause section.
Meanwhile, we have a related FAQ-[Motherboard] Troubleshooting - How to solve BSOD error in Windows(Blue Screen).

Additionally, we would like to inquire about the model you are currently using, whether it is the PRIME Z790-P WIFI-CSM or PRIME Z790-A WIFI-CSM.
Could you provide information on the driver that was updated before the occurrence of the BSOD and the current version of your BIOS?

Thank you.
