Question Fans and everything working but not booting up, neither no light on keyboard

[DevilSlayer234]

I've have Gigabyte B450 DS3H mobo paired up with Amd Ryzen 5 3400G.
I was installing a new GPU Which was Nvidia RTX 2060 super. So I plucked out the old GTX 1050ti put new one in But No display! I tried again and again but no luck.
I've Corsair VS 650 watt 80 plus PSU which I bought somedays ago.
I thought New GPU was defective so removed it and back to old one but no luck it's not booting up
I tried without GPU too but it's still pitch black on monitor

You more than likely need a BIOS update to support that 3400.

Wait...so it was working before a GPU change? Or is this a new build? Confused!

It was working fine till I put new GPU.
It's an old build and I was upgrading it.
I put new PSU, 8 GB extra RAM and 2TB HDD.
It all worked fine with old GPU. But after plugging new one it's dead

Did you use DDU to remove the old GPU driver before installing the new one?

Remove the new RAM you installed.

Give that a shot and report back with results.

Well how am I suppose to do that.
I don't even get the screen
And even without GPU it's not booting up.

Remove the GPU and plug monitor into motherboard HDMI. Install a single stick of RAM in the 2nd slot. Clear CMOS following directions on page 18 of the manual.

Hi
This is a long shot but can you remove the Mobo from the case and also release the screws on the backplate of the cpu cooler. A short circuit from the backplate/case/Mobo caused the same symptoms

I solved the problem by putting isolation rubber rings around the screws (each costs like 2 cents)

I may dumb af but where is manual?
Btw I see two jumper near front panel in mobo written Clr_cmos on it.
Do I need to shot em with metal when power is on?

Turn power off at the PSU switch, then short the pins for 10 seconds or more.

I didn't work
I tried battery reset method too didn't work out.
I just wanna know which part is causing this problem.
RAM nah I don't think that cuz at least one of em should've worked
PSU I have two spare PSU didn't work
So i think its gotta be Mobo
Or that new GPU was defective and It also wracked my MOBO

Try a different PSU. The VS series from Corsair is crap quality.

I had the same issue so I gave up that night and woke up early in the moring to solve the issue and well it turns out the issue was with the RAM at first I just put the RAM in all the slots that didn't work I had to put them in order for my motherboard the RAM order was A2 and B2 than A1 and B1 after that I fixed the issue. Hopefully it would work for you.
