Computer wont POST after Secure Boot is Enabled

[iMxmo]

Just want to get Secure Boot enabled in prep for Windows 100, but upon enabling it via BIOS/UEFI my system doesn't enter the OS at all, and brings me back to UEFI screen. 

CPU: R5 2600X
MOBO: B450 SL M-ATX
RAM: Ballistix 3200C16 (XMP was enabled throughout testing)
SSD: Crucial P1 1TB
PSU: Phanteks AMP 550W 

 bios version: 3.70

I wonder if your CPU isn’t supported

Damn, your mobo's basically f*cked now. Your mom should get you a new one tbh, unless you can get a replacement through the warranty.

A computer shop might have a BIOS-programming tool that can flash the BIOS-chip on the mobo.

nope just check with two of the pc repair shops, they don’t do bios reprogramming or resoldering. might just order a new motherboard like a b550 aorus elite and just try to diy this with a CH341A, if asrock declines my RMA
