   I just put together a new computer and everything was fine for the first 10 days.  All the temps of GPU and CPU were in the 40-60 degree range.
Today the motherboard shows a 00 and nothing goes on.  No video. Nothing.

870e Nova MB
AMD 9800x3D cpu
32 G ram
5070 video card 
Coolermaster 1000 watt PSU
M.2 drives

	Updated bios to 3.20. Turned on computer and got a C5 error. Took out ram and moved to A2/B2. Seemed to solve the problem. Fingers crossed. Thank god for the flash bios feature.

	I had a similar issues, I ordered my part from newegg.com but my motherboard is the x870E Taichi paired with the R9 9950x3d, after installed, I was able to boot to the BIOS but after 10 seconds it went black, no display, no power to keyboard, no power to mouse, and code reads "00" I flashed the bios to the must current didn't work, I flashed to another version no working, I swapped PSU, I swapped DDR5, I re-seated the CPU and CPU COOLER still not boot, code "00" I then decided to RMA CPU and Board to newegg.com for replacement. dannnng, I 'm glad you got your fixed but me very disappointed for my setup.

	Well, I guess we'll see how long it lasts. I do not understand why it worked flawlessly for 10 days. If it did not work from the git-go, I would have not been so perplexed.
