Question CPU & DRAM EZ Debug Leds flash once when I start my PC & it doesn't POST ?

Jul 26, 2020
So i just finished building my pc but that happens My specs are B350 pc mate Gtx 1070 Ryzen 5 2600x Corsair vengeance 2x8
I have tried almost everything in this thread:
This is my first build so im kinda stuck so i kinda need help.
Heres a vid:
sorry for the low quality vid streamable compressed it heavily
The trouble shooting LEDs do come on and when they go out then all is OK.
At that point your Bios hands over to the Operating system.
Ram is OK, Dram is OK, Vid is OK and Boot drive is OK.

It could be when windows starts up with driver issues.
Can you start with Safe mode?
