Question

Third time getting red CPU light. Please someone help.

I have gotten the red CPU light twice before and now I don’t know how I got it again. The first time I had my computer for a week then it decided not to work anymore so I replaced the CPU. That gave me my second CPU light so I tried replacing my motherboard and that fixed it for about to weeks. Today I tried to activate windows and after it activated the whole thing froze so I tried turning it on and off then I gave me my third light. Is there anyway to fix it without replacing more parts.
Motherboard: Gigabyte AB350-gaming 3
CPU: Ryzen 5 1600
GPU:GTX 1080
EVGA: 650 GQ 80 Plus
RAM:Kingston Hyperx 8gb kit

Still in warranty. However

The thing I keep running into Ryzen is that the BIOS SHALL be current. This can really test a builder's resolve since many FEAR updating the BIOS. I can not overcome that fear so if you can't do this, then have it done.

If it's dead, call the maker or supplier and ask what to RMA.

Bios

What bios should I try to flash for my computer?

Before that. Read about heatsink compound

There are many new builders today. I run into a few that think compound is optional.

As to which, the one that the motherboard maker tells you is the latest for this board.

My Heatsink came with CPU

My Ryzen 5 came with its own heatsink which had its own compound on it.

can you enter the BIOS?

Check to make sure the CPU isn't overclocked. If it's not, then underclock it for awhile, see if the problem changes any, or disappears. Also while there, check the RAM settings, and dial those back some too.

Checking CPU

The computer won’t even start. How do I check it? This is my first build.

First time you said it wouldn't start at all

You better open it and check all things like CPU, RAM seating, PSU plug to motherboard, etc.

Starting the computer

When I turn the computer on the fans on the cpu and case turn on. The logo on the gpu lights on( meaning it’s on) but the display won’t turn on and the red cpu light is on.

that doesn't sound good

Hope it's not burnt dead.

Use some silver based thermal paste on HSF/CPU connection.

I think your problem is entirely heat related.

Not the difference in application method
