I have a older gaming computer I am working on for a friend. It has a Fatal1ty P67 Pro mother board with a i7 processor. The problem is when I boot the system up normally to windows 10 the CPU is always at 100 % usage, never drops and eventually crashes. The HDD and memory are always at low percentages. Ig I start in safe mode the the CPU is where it should be. I have tried 2 separate clean installs of Windows 10, I have updated drivers, I have disabled some drivers, I did a clean boot and unchecked all non Microsoft programs at startup, I have checked the memory, I tried a different video card, I removed heat sink and applied fresh thermal paste, ran file checker and still the same results. This is a gaming laptop so I reset the bios and tried to put all setting to default. The CPU temp is usually under 40.
The only things I have not checked is the CPU and motherboard.
Any suggestion would be appreciated

while we wait for the Speccy report, and don't forget the make/model of the power supply, and assuming the CPU is not faulty....

the P67 is a desktop motherboard, but you say it's a gaming laptop - is this right?
and is it about 10 years old?

when you reloaded Win10, did you have the PC disconnected from the network.
and after installing Windows, and before going back on the net, you reloaded the drivers from the mobo's driver support page?

at each stage of the reload, see if the CPU usage is spiking, so right after the initial OS reload, then after the driver reload, etc.

I did a clean install of Windows 10 Pro a few days ago and loaded all drivers from manufactures site and today I attached a new SSD drive and did a clean install of windows 10 with no internet connection and checked CPU usage as soon as it was installed and it was at 100 %. I have installed Windows dozens of times to all different makes of computers in the last year and I can usually figure out the issue but this one has me stumped. I will get the CC cleaner report tomorrow and post it. Thanks

Yes the Motherboard is a Asrock Fatal1ty P67 Professional. It was overclocked and had a liquid cooled CPU cooler when I got it. The CPU temp was running in the high 90's when I got it because the liquid cooler pump had failed. I replaced the liquid cooled system with a air cooled heat sink & fan and removed all the overclocked settings in the BIOS and the temp is now below 40. I am leaning towards a bad CPU at this point.

Here is the PSU and the Speccy report

I ran a program to check hardware usage, and the CPU usage from OCC program is not close to what is showing in Windows task manager.
I did forget to mention that when the PC crashes I do get a message ( Stop code: KMODE EXCEPTION NOT HANDLED ) on the blue screen for a few seconds

We need the link to the speccy report not a screen shot which does not show us a complete picture of the system.

See if this helps explain better of how we need the report as.

Do not forget to post the make and model of the PSU if this is a desktop.

Download then run Speccy (free) and post the resultant url for us, details here, this will provide us with information about your computer hardware + any software that you have installed that may explain the present issue/s.

To publish a Speccy profile to the Web:

In Speccy, click File, and then click Publish Snapshot.

In the Publish Snapshot dialog box, click Yes to enable Speccy to proceed.

Speccy publishes the profile and displays a second Publish Snapshot. You can open the URL in your default browser, copy it to the clipboard, or close the dialog box.

The processes that show to be using the CPU are very erratic, they change very quickly and continuously and the ones I am able to close don't affect the CPU usage
