PC experiences unusual visual distortions, freezes, and excessive heat.
Since I assembled my PC, I’ve encountered some unusual problems.
The initial challenge began immediately after completion. After installing all required drivers and launching a game, the response time was extremely slow—my system barely reacted to key presses, taking several seconds for actions in-game. The input lag was severe, making it difficult to control the game smoothly.
I attempted a second Windows installation via USB, but it didn’t resolve the issue. Eventually, using the built-in reset option instead of a USB helped eliminate the delay.
Since then, another complication has emerged—visual anomalies. They appear as incomplete redraws or something similar (the exact description was hard to find), and they mainly affect applications such as Discord and web browsers (Chrome, Brave, Edge, Firefox, etc.). The problem also shows up in the BIOS and seems to occur during recording, with differences when recording versus not.
This issue even appears in the BIOS settings.
It usually happens in the same way I experience on Medial, where certain apps like Discord or Chrome pages sometimes don’t refresh fully, leaving parts still from the previous frame while others are responsive. This also occurs with Spotify; the glitch is present during recording but slightly altered, similar to what I see in the BIOS—there’s a pixel visible but it updates when the cursor moves over it.
I’m not sure what’s triggering these visual disturbances.
It might be connected to the hardware acceleration path or possibly a power supply issue. I’ve also faced frequent overheating; even minimal activity causes fans to spin up and CPU temperatures to rise sharply. I initially thought it was CPU-related, so I swapped it out, but the problem remained unchanged.
I’ve replaced most components except the CPU, which I upgraded, yet performance hasn’t improved noticeably.
Here’s a summary of my PC components:
- CPU: Ryzen 7 7800X3D
- Motherboard: Asus B850-A Gaming Wifi
- GPU: Gigabyte ice RTX 5070
- PSU: Corsair RM1000x
- AIO Cooler: ARCTIC Liquid Freezer III Pro 360
- RAM: Crucial Pro DDR5 32GB (2x16GB, 6000MHz CL36, CP2K16G60C36U5W)
- SSD: WD_BLACK SN850X 1TB NVMe, PCIe Gen4
My history of upgrades and troubleshooting has been challenging. I’ve had overheating concerns before, which affected fan speed and CPU temps, but nothing resolved the core issues.
I’m still trying to figure out what’s causing these visual problems.
If you know a better way to share this issue, please let me know.

Welcome to the forums, newcomer!
Have you transferred the OS drive from your previous system?
Please note the make and model of your case. It might help to show images of your PC's internal setup—such as fans in the wrong position or leaving the protective plastic cover on the cooling block—which can cause overheating.
I attempted a second Windows installation via USB, but it didn’t resolve the problem. Eventually, I fixed it by using a fresh Windows install through the built-in reset option rather than a USB drive. That resolved the delay issue.
Where did you obtain the installer for your operating system? How did you generate the bootable USB for it? Did you recreate the installer to check for corruption? Were you installing in offline mode?
Motherboard: Asus B850-A Gaming Wifi
BIOS Version: Check your motherboard model.
Disable the iGPU in BIOS, then use DDU in Safe Mode to remove all GPU drivers (Intel, AMD, Nvidia). Reboot and install the latest driver from Nvidia’s support site using an elevated command—Right click installer > Run as Administrator.
the first time i installed windows it was from a whole diffrent laptop using media creation tool, Windows 11.
., and when i swapped components and bought a new gpu installed windows freshly with a USB drive again from the same pc before swapping components.
My case is the NZXT H9 FLOW , and the plastics in the cooling block are removed,
My Motherboard version is version 1078, there a new one that came 6 days ago so i'll update to it soon.
im about to try what you recommended me to do, i'll very soon let you know how it went.
So I turned off the iGPU and used ddu in safe mode to remove the GPU drivers, then installed the newest NVIDIA driver and gave admin rights, no changes. Still the same problem.
I asked about the source of the installer for my operating system, how the bootable USB was made, whether I recreated it to avoid corruption, and if I used offline installation.
I downloaded Windows using my previous laptop with the Media Creation tool, and created several versions on both my old laptop and a new PC. I reset the PC many times, mostly using a command to indicate no Wi-Fi access, and then transferred Ethernet drivers via USB to my PC.
Additionally, I have a recent video recorded today about a game called Cities Skylines II. In the clip, when moving objects in the game, they leave behind a pixelated tray or artifact, which disappears when scrolling—similar to what happens with other apps. Here’s the link:

Edit:
My PC also becomes noisy when performing any task, sometimes even in idle mode. Opening a browser can cause it to get loud, and at times it gets very loud. Also, in this link I added a screenshot of my PC: red indicates exhaust, blue indicates intake.

I fixed it now it should work
I used a DisplayPort cable connected to the GPU and then to the monitor.
This is my first time hearing about the QVL list, how do I access it so I can check?
I’ve applied a lot of thermal paste, NT-H1, and my PC overheats without any reason. It doesn’t stay at stable high temperatures; it just gets really hot when I run normal tasks for a while and then drops suddenly.
Also, I updated the link so you can see it now—I think here you’re in.

I can open a new tab in Brave and the PC instantly gets louder, with temperatures usually around 60-70°C. Then it drops back to normal quickly. Usually I stop checking the temperatures because I’ve memorised the approximate temps just by listening to the fans 💀. Sometimes nothing changes, but the temps spike even without doing anything. Lately I left the PC idle for a while and the fans calmed down for a few seconds before getting louder again.
All the videos you've reviewed point to a driver problem, in my opinion. Which driver version are you using for your GPU? What versions have you previously tried? Did you upgrade to BIOS version 1087? If so, did you reset the CMOS? You should reinstall the newest chipset driver through an elevated command, such as right-clicking the installer and selecting Run as Administrator.
I really think it might just be a driver problem, even though I installed and reinstalled them thousands of times.
Right now I’m using the newest GPU version released on September 30, 581.42, and I always keep the latest drivers installed. I upgrade them whenever necessary.
I always switch them off in Safe Mode and back on in normal mode.
I tried all possible versions since I built my PC in February 2025, but nothing changed.
Just recently I updated the BIOS about half an hour ago, though I haven’t cleared the CMOS this time—I’ve done it before, so I’m sure it can be done again.
Six days ago I installed the newest chipset driver, and I’ll try it once more, even though I doubt it will make a difference.
I keep reinstalling, removing and reinstalling these drivers over and over, but none of it seems to help.
Also, I left my PC running for about 40 minutes while idle—only Spotify and Brave were open, with a few tabs, and I’m sure nothing like that would cause the fans to increase unnecessarily.
This keeps happening every few minutes without any reason.
