AMD RX 480 4GB driver problems often stem from high CPU utilization.
Hello, your CPU usage stays low at idle but spikes during gaming. The issue disappears when you remove the AMD GPU driver. I checked both the newest and older Windows 10/11 drivers; it turns out the problem is linked to a GPU kernel process that can't be closed or resolved. The only workaround is switching to Windows 8.1 with the latest driver from 2017 (a very old one). This explains why you're losing CPU power without any clear reason.
CPU model is i5-4590, GPU is SAPPHIRE NITRO RX 480 with 4GB RAM. Motherboard type H81M-P34. Memory includes two 4GB units via HyperX Furry DDR3 at 1866mhz. Running on Windows 10 version 8.1 with the most recent drivers from 2017.
You cannot terminate or stop system.exe. It is essential for your system to operate. You can check the details about this process. It belongs to the (NT Kernel & System). I run it on my machine and others too. My setup uses an AMD graphics card, but it also works with Nvidia cards. Refer to the links shared by users who faced similar problems two years ago, as well as another source from someone experiencing the same issue. Make sure to use the latest drivers.
I've never come across this fix. It sounds like a big deal. I rely on DP on my monitor's back. Thankfully it's been fixed.
It's quite unusual, not sure what's causing it—maybe the HDMI cable or the GPU. I have to disconnect it every time I start Windows, only functioning after a short delay. I wait a few minutes, then it works until I restart the PC again. Even after updating my BIOS, the issue persists. I'm considering getting an i3 12100f and possibly an RX 6600 in the future.
After checking your message, it seems the issue lies with your monitor or the HDMI cable. It’s probably the monitor that needs adjustment through its buttons, and I’m able to change settings myself, like color options. I don’t know your monitor model or brand. It’s possible you can adjust it using the AMD control panel as well.
You're correct, the issue seems to be with the monitor. I own an older 720p model with speakers, which supports HDMI audio. My 1080p monitor works fine even with HDMI (it has both VGA and HDMI inputs), but it lacks built-in speakers—possibly due to AMD driver problems. Interestingly, it sometimes experiences timing issues during BIOS boot, showing a blank screen or waking up after a delay. I tested my PC with that 1080p monitor and it started without any CPU load, confirming the monitor is the culprit. The HP 24e 1080p at 60Hz model is another one I’ve encountered; I once cleaned dust from it, but it still developed lines, which I didn’t suspect as the cause.
