Unresponsive during disk I/O on first boot

[RobWithTheBigPC]

Brand new system, so hard to pinpoint cause. Symptoms: on first boot, the mouse will seem unresponsive. Freezes up, moves in little jumps, low sensitivity. Keyboard, similarly: types keys buffer for a second or so, then all appear at once.

Then the system will work smoothly for a few seconds. Then go back to being unresponsive. The unresponsive-ness seems to coincide with disk activity. If I see the disk light flash, or I open a file or start a program, that's when it will be unresponsive for a few seconds.

If I reboot, everything is now fine. So it seems like something to do with a difference between a cold start and a warm start. That makes me think of firmware/BIOS/drivers.

Most BIOS settings otherwise default apart from turning on EXPO and disabling iGPU.

Exact same issue. I can tell it's going to happen because the RGB on my mouse (HyperX Pulsefire Haste) tries to cycle but resets over and over. Keyboard RGB is fine but almost impossible to type my PIN to enter Windows.

If I reboot, everything is now fine. So it seems like something to do with a difference between a cold start and a warm start. That makes me think of firmware/BIOS/drivers.

Same thing I've noticed. If I restart through Windows, it usually happens. Same with booting into bios, save and exiting into Windows.
Mouse and keyboard are also sometimes completely unresponsive in bios or causing issues.

One thing I've seen work so far, at least for a temporary "make the mouse and keyboard work" is putting them into the USB 3.2 Gen 2 ports. By default I put them in the USB 3.2 Gen 1 ports.

Well there is a lot gone on to get the information on the screen, and sometimes it helps to understand watching the 'even viewer' windows log/system. Stay out of application and other things, use only the system to monitor. This is all windows... don't worry about too much, but the red '!' ain't no good. Even then, it doesn't mean it will be a problem to your computer. Most things fix by itself.

Most issues are not the power if we are talking about thumb drives. Do not mess with the power plane on the drives, it will cause you more problem. But again, two low power on boot ain't no good. It will delay everything, but makes it more stable if you like. CPU has a max voltage, and when the curve will go over that, it will force it to stay lower. Even when you start to OC, unless you turn off most important fail safes to keep it balanced. Not a circumstance you want to get in to, so don't go too high increasing that. And with newer chipsets, I would not recommend the OC at first. You would be better off with a smooth working system. What I should do is increase the voltage on the CPU at boot. It would not arm if you don't change it. Anyway, every computer needs some time to boot. Better to let it do for a few minutes, and not been impatient like me.
