Hi, This is the new AIO PC bought few days back. I am facing high CPU issue intermittently. Task Manager shows a process 'system' is taking more than 70%. Resource Monitor shows 6-7 cores are peaked out to 100%. My PC was running a few chrome and edge browser tabs at that time. I killed all the browsers but still high CPU stayed for 5 minutes or more. After 15 minutes, PC came back to normal level and responsive. The issue recurring every day. Raised ticket with HP and technician Reset the OS via F11 option. However the issue was not resolved yet. Please help.

Welcome to the HP support community.
I understand that your notebook is hanging, I am glad to assist you.
Turn off the computer.
Disconnect all external connected peripheral devices such as USB storage devices, external displays, and printers.
Unplug the AC adapter from the computer.
Press and hold down the Power button for about 15 seconds to drain any residual electrical charge from the capacitors that protect the memory.
Press the Power button to turn on the computer.
If a startup menu opens, use the arrow keys to select Start Windows Normally, and then press the Enter key.
Second, you can check if there is Bios update available for your PC, here is the link to download.
Performing a test on the Hard drive as well as on the Memory from the Hardware diagnostics:
1) Shutdown the computer.
2) Turn the computer back on again and repeatedly tap on the ESC until a Startup menu appears.
3) Press F2 once for System Diagnostics.
4) Go to Component test.
5) Run extensive Memory and Hard Drive test.
Depending on the test results, If the test passes then I would suggest you perform a complete system recovery.
Note: Recovery will wipe off everything from the computer. If you have anything important get in touch with some local stores to get your data backed up.

Thanks for your assistance. I could isolate and resolve the issue. Memory leaking in browser caused available RAM to drop drastically causing the system process to take overhead. Even after upgrading the RAM to 16 GB, the available memory drops from 10 GB to 2 GB within an hour time of my regular usage. All that I use is a couple of browser tabs with tradingview charts. First disabled Mcafee safe browser extension resulted to a great difference in performance. No severe leaking. Still GPU process was taking considerable working set. So disabled hardware acceleration. Problem sorted out.
