Hello,
I'm brand new to PC building and I just built my first PC about a week ago. At first it was working fine except for having to choose which Windows installation to use every time I turned the PC on. It would ask me whether to choose the Windows installation on my SSD or HDD as I hadn't wiped my HDD beforehand (I had it installed in the rig for storage) and it started having issues after I turned off the option to choose which Windows Installation to boot. It would start but then instead of booting Windows it would black screen and only boot into Windows after doing automatic startup repair. When attempting to select my SSD as a boot drive it would tell me to select a valid boot drive, so I thought that updating my BIOS might help fix my issue. After downloading the BIOS update from the manufacturer's website I used M-Flash to update my BIOS and now it no longer POSTs. When I turn it on, my keyboard and mouse RGB flash for half a second and nothing appears on the monitor whatsoever.
I'm worried the issue is that I updated my BIOS to a later version that dropped support for my CPU. Is there anything I can do to fix my problem without having to replace my motherboard or CPU?
I've tried:
CPU: AMD Athlon X4 950 @ 3.50 GHz
GPU: AMD Radeon RX 460
RAM: OLOy DDR4-3000 16GB (2x8GB)
Motherboard: MSI A320M-A PRO
PSU: EVGA BR 450W

I've tried:
- Running with only 1 stick of RAM installed
- Swapping RAM sticks
- Unplugging both my SSD and HDD
- Taking the CMOS battery out for 15 minutes
- Shorting the JBAT1 header to clear CMOS
- Using a stock keyboard and mouse
- Resetting BIOS without anything being displayed on the monitor
- Plugging in an HDMI cable instead of a DisplayPort cable
