Question Why is my VGA LIGHT ON - ryzen 3600x 980 ti

[Clearoot]

OK so I've just bought new ryzen.

I purchased 3600x
B450 tomahawk
3200hz ram

I'm still using 980 ti
And 600W corsair psu

I flash updated the bios to support latest ryzen 3000 series

I have everything built. Pc switches on all fans running including gpu but after 5seconds ish the gpu powers off and the VGA light comes on.

Pc isn't posting.

All lights on mobo work cpu appears to be working and same with ram as there is no debug lights comin on.

I have used this gpu for a year and it was working fine a few days ago.

I have same problem.
At first it was cpu light, but if i cold start computer i can get in to windows.
After radeon vga driver update my mobo goes from cpu to solid vga light.
Have tried bios 17, 18 and 19.
Diffrent GPU nvidia
Not Even cold start work anymore

Stuck at vga light.

Ryzen 3600
B450 tomahawk
Vega 64

Hey, I found why my VGA light was on. Since it was a new build my pc wasn't booting to windows and apparently the mobo doesn't give power to the gpu whilst posting so this was flagging as an issue.

If you haven't already don't assume it's not booting to bios based on the vga light like I did

Hope this helps.
