Not posting- Please help

Pc will not post

I had a fully functional pc. (Ryzen 5 1600, GeForce rtx 3060, vengeance rgb pro ram,) Never had problems. I then did a bios update in which the pc shutoff in the middle of it. From there I turned it back on and my monitor said no signal found. Thinking I bricked my pc I went and bought a new motherboard I bought “ TUF gaming X570-Plus (wifi) AM4 board. I went and installed it. When I was done I’m having the same problems as with my last motherboard and it won’t post. There is a white VGA light on the debug. I have and another gpu which is good and swapped gpu and stil didn’t post. Please help.

 

(and yes I tried different monitors, HDMI, DP cords, plugged both hdmi and DP cords into both gpus and motherboard)

did you read that it supports that CPU still?.. thought the older cpu's was removed at some stage ... 

try to find the original bios and do a flashback.. 

 

you can still save your "bricked" mainboard but you will need to get an eprom writer.. and those are dirt cheap... depending on your mainboard you might have to solder some...... or get someone to do it for you.. ...... or get a newer cpu that supports those bios'es you flashed to your board.

Hello.
You did a BIOS update? with a Zen 1 CPU? On what board? What speed RAM are you using as this may also be a reason why your PC isn't posting. Which BIOS update was it? I need answers to all these questions. If it was the latest BIOS thats come out you may have made a costly mistake (and your board doesn't have a DEBUG LED either so its pure guess work as to what part of the boot process isnt working.)

Also 500 series boards (that new board you bought) don't support Zen 1. In fact any BIOS that has come out since about Zen 2 I think (so X570 and B550) dont have support for Zen 1 only Zen+ and above. Then there are the newer BIOS updates to support Zen3 on X370, B350, X470 and B450 boards as well which may remove support for Zen 1 and Bristol Ridge (pre Ryzen) APUs. If you have another CPU test it out and see if it works on both boards. If it does there is your reason why it no longer POSTS.

If you don't have a spare Ryzen CPU (you have a 1600 so you probably don't thinking about it) you might want to take it to a shop where they have a CPU you know will be compatible or where they can update your BIOS.
Also did you lose power at all during the update since it shut off during the middle of it?

 

Your XMP profile RAM may also be too fast (if the board you were using still does support Zen 1. My 2700X no longer posts with its XMP profile at 3200 speed (i need to set it to 2133) because support to enable these speeds was removed I think.

Also heres a diagram that shows what CPUs AMD definitely 100% supports https://www.tomshardware.com/news/amd-zen-3-b550-x570-motherboard-compatible
Support for Zen 3 on 300 and 400 series boards (and support for Zen 2 on 300 series boards) is an afterthought. It works 100% fine (I used it on my X470 taichi) but it removes support for older processors as I just said and I myself would not have done it if I didn't know exactly what I was doing and wasn't into this as a hobby.

Yep. As a general rule only do a BIOS Flash if you know 100% your motherboard and CPU will work together (you need to check to make sure.) Sadly the newer board doesn't support BIOS Flashback (not sure about the older one as we don't know). As I was answering the post/question I looked it up.

The easiest hassle free thing to do would buy a used CPU at this stage (like a 5600X as they are dirt cheap now) and try sell your old one to try and recoup the costs but obviously used can be hit or miss so to fix it you need an EPROM writer as Robhcii said or I'd just take it someone to see if it can be fixed.
