PC WONT BOOT. BIOS???

[Nidal Hussein]

Hey, hope ya’ll doing great and had a wonderful Christmas. I’m running into an issue. I just finished building another system but it’s not booting. The motherboard was previously being used with a R5 3600 but is now paired with a R5 1600. Do I have to flash the bios back? Could that be the issue?

There aren't any motherboards specifically with a BIOS that works fine with a 3600 but not a 1600. Motherboards that drop CPU support are pretty much for the A-series APUs.

 

Is this a B550, A520, or X570 motherboard? If so, those chipsets are not compatible with first gen Ryzen, and only the X570 is compatible with second gen.

It’s a B450 motherboard. It’s running a 1050Ti too.

Compatibility should be fine. Is this a brand new CPU? Also, did you try different ram configurations?

 

If this is 3600MHz ram for example, the first Gen CPU might be struggling with the jedec spec of the kit.

I'm fairly certain my old b350 *did* drop support for older cpus when i updated for the 5800x3D ...not sure (but there definitely was something lol) 

 

ps: last part you're definitely correct, which is why people should post SPECS when asking for help.
