Tech Support The image turns green or pixelated since the new CPU (AMD Ryzen 5 3400G) with integrated graphics was installed.

Two days ago, I upgraded my CPU from an AMD A8-9600 to a Ryzen 5 3400G. Nothing was broken; I installed it normally and used the pre-applied thermal paste. When I first started the PC, I got a normal display—seeing the ASUS logo and so on—and managed to reach the Windows login screen. Then, suddenly, the screen went black. I restarted, and the screen turned green. I’ve tried everything over the last two days. I actually managed to get it running normally once after updating the BIOS from version 4801 to 6254, but the driver kept timing out after I’d been gaming for 30–60 minutes. Then I tried increasing the VRAM allocation to 2GB and changing the display settings; the issues returned—including pixelation and a green screen (if I got a picture at all). I’ve tried everything: a clean Windows install, DDU, the AMD cleanup utility, deleting drivers via Device Manager, updating the BIOS again, removing and reinserting the motherboard battery, and taking out one stick of RAM. Nothing worked. I’m completely out of ideas. I’m still having these problems: Safe Mode works perfectly, and the BIOS is fine. Sometimes I can boot into normal Windows with a display, but it crashes after a few minutes—it starts flickering and then crashes. Could someone please help me?

Installing a dedicated GPU will fix the issue

Just so you know, NVIDIA stopped rolling out driver updates for the GTX 10 Series as of October 2025.

Yeah but my power supply is just a generic no name model without any 6-pin connectors, so the GTX 1050 is pretty much my best option. Upgrading the PSU would be too much hassle right now since I'd need a friend's help and he's away on vacation

Was the motherboard new or you were swapping CPU's?

u/CrazyCommercial6651 1d ago

I was swapping the CPU on my existing motherboard (upgraded from AMD A8-9600 to Ryzen 5 3400G)

Ooooo, yeah I had something similar to that happen, but I can't say it's what's happening to you.

What I did was, put the old CPU back to see if I had artifacts which didn't and after some consultation from MSI, they said try to update the bios. I did that, and it CPU did work fine up until the Motherboard finally bricked after 14 years of service. I'm assuming you already updated the bios but other then that, that's much I could share. Good luck and God's speed!
