[SOLVED] New CPU

[james222277]

I upgraded my CPU from a Ryzen 3 to a Ryzen 7 5700g. Before installing I updated the Bios to F51G as recommended. The motherboard is a Gigabyte GA-A320m-HD2 Rev 1
I get no video out from the graphics card or the motherboard. Computer starts up, fans are running but no picture. The power button will turn the computer on but not off. I tried resetting the CMOS, did not work. I put the old CPU back in and it works fine. Any suggestions?

Are you using displayport?

What Ryzen 3 did you upgrade from?

How, EXACTLY, did you try "resetting the CMOS"? Every step involved matters so please be concise.

Ryzen 3 1200 was the old CPU.
To reset I removed the battery, left it out for 20 minutes and also connected the cmos terminals. The PC was unplugged for this part.
I'm not using displayport. Output was a HDMI and I also tried DVI connector.

When you updated the bios, did you immediately go to F51G or did you read the bios notes and update in some series?

First should have updated AMD Chipset Driver 18.50.16.01, then update to F31, then can update to F51G.

Yes I had to do 2 updates. It wasn't possible to go to F51G first

I want to say to check the 5700G for any bent pins. Updating bios and resetting cmos should have cleared up any boot issues, it can sometimes take a reinstall (can be done with No loss of data) of Windows to get that working right.
Can also try updating to F51h.

Hard to "reinstall Windows" if there is absolutely no display after changing CPUs. Can't really be a Windows or driver issue if there is not even basic hardware level display support that allows you to see the POST messages and access the BIOS.

That usually means lack of CPU support from out of date BIOS, bent pins on the CPU or motherboard or some other hardware level issue. Or simply bad CPU, which we've seen A LOT, coming from Newegg and Amazon. I know damn well they get a lot of returns where somebody has popped the cork on the CPU and returned it, and they send it right back out to the next guy after making it look like it's never been opened before. I've seen it multiple times on here and they've tried that crap once with me as well. So, it absolutely happens.

Well that's just the thing. There are some unknowns. The motherboard and old cpu and gpu work just fine, also there's no mention of exactly what

I get no video out from the graphics card or the motherboard. Computer starts up, fans are running but no picture.

that means, whether the monitor turns on at boot but gets no display except a black screen, which could mean it's actually getting into bios and stopping at 'hardware change detected, press F1 to go to settings' but has no display to show that or whether it doesn't even turn on in the first place or even make it to bios functionality.

Op could have the bios set for PEG as primary, and detecting the gpu installed, so isn't/won't switch to the igpu, but there's some reason the gpu isn't outputting a signal, like the bios update has reset the defaults to Auto or pcie4.0 and the new cpu isn't making that connection yet.

If the pins are not bent, could try pulling the gpu out entirely, forcing bios to use the igpu, or put the gpu in the secondary slot temporarily, which uses the chipset pcie lanes not the cpu pcie lanes.

Actually, he was pretty damn clear about that unless he was completely off.

Computer starts up, fans are running but no picture

That tells me exactly what it says. Power on. Fans run. There is no display. Hardware or BIOS level issue. Still could be a lot of things, but I find it very hard to believe it's anything related to Windows AND besides which, there is literally no way to install Windows or anything else if you have no display.

Thanks everyone for the help. I'm going to chalk this one up to a bad CPU. I got if off Amazon so I returned it then went to best buy and got a new one. I installed it and the computer is running now.

So, as I said, bad CPU right out of the box and likely they just sent you one somebody already torched. Well, at least it was relatively simple. All things considered. I've seen some of these threads just go on and on and on even after replacing basically everything so at least you didn't have to do that.
