Windows 10: Laptop performance sporadic following upgrade. reason unclear

Running a Compaq Laptop with W10 and I'm experiencing something new. First the details of the hardware: Winver: 10home. 20H2 19042.1052. Feature Pack 120.2212.2020.0 PC is an AMD E1-2100 APU with radeon HD (1gb), 4gb of DDR3 installed, on a 64bit system. Following "issues" it's had a blank-drive reinstall from an existing disc. The 21H1 build refuses to work on this machine. Initially the install appears flawless, but there is something hinky going on in the background. There is something interfering with the smooth running of the system, it's using up about 2 out of every 10 cycles is the only way I can describe it. Everything works, but there is a noticeable interrupt that takes up 1 second out of every 5. mouse moves 4 inches on screen and stops for a moment, then continues. If there is a process, like the update screen with it's spinny blue dots, that "pauses" every few seconds. Task manager has the CPU running at around 50% pretty much all the time, never less than 35% and sometimes at 75%. it's like there is a hidden process that's chewing up the available runtime. all TM says is "system", there's nothing strange in the neighbourhood, this is a clean system. Tried reformatting the HDD again and re-doing the install, same result. Reinstalled offline, refused internet connection and all was good for about 4 minutes when it burped a random beep and all was stutter-y again. Tried it with and without updates, nothing makes it different so far that Ive tried. Ran in safe mode and all is ok, so it's possibly a system process, but I can't identify it. I have ordered a bigger stick of RAM to give the CPU some help, but it's just plain annoying that it's not behaving. I could understand slow all the time, or BSODs, but can't see what it's doing this. Is it simply that this laptop can't handle Windows10? Surely not? Any help is greatly appreciated

Laptop performance sporadic following upgrade. reason unclear

Hi, what is the model of the laptop? How old is it?
Please quote the driver download page URL.

Has it run Win 10 successfully previously?

What was the last version or build of Windows that ran on it successfully?

How does it run in Safe Mode?

Please post a screenshot of the task manager, processes view, at least, say, 4 mins after booting and logging in thus:



organising any columns of interest high to low by clicking on the appropriate column header.

Then do the same with Process Explorer (free from MS) expanding the process of interest to see more detail.

This appears to be an underpowered machine:

Was the O/S originally supplied 32 bits or 64?
Which of these is the installed O/S?

If 64 bits, are there any 64 bit manufacturer-supplied drivers?
