Windows 7: CPU Usage @ 100%

I'm thinking the 3rd party program you are using after you shut down Task Manager and Process Explore to read cpu usage is not working correctly.
You could try removing that program and monitor your temps while using Task Manager and Process Explorer. Jumping for 30 to 50c is a big jump.
What is the name of this program.

The program I use to monitor CPU usage is a gadget called System Information. I have used this without issues for years. I tried disabling it. No change.

I'm basically thinking about reinstalling Windows, however I get the feeling the same problem will arise. The 3rd party programs are pretty much the same ones I've been using for years.

I thought about a bad reading being the cause, but how would it account for the increased temps in HW Monitor? (Also another program I've been using for years). *scratches head*

ATM, I've left Task Manager open to stabilize the system. This is the only way I can keep usage and temps stable.

Could it be a hardware issue?

I think I solved the problem.

I created a new account on Windows. After switching to the new account, the issues disappeared.

Don't know why though.....but will monitor situation.

Thanks for your help. Have a great weekend.

Sometime a program like the gadget you are using to monitor need to be removed not just disabled.
Here is my thoughts.
1. HW Monitor is a quality program and should be giving correct readings.
2. Process Explorer is a quality program and shows nothing unusual running.
3. Something is running or it's a false temp reading generated by something.
4. Task Monitor is reliable, and doesn't know how to lie unless something has infected the computer.
5. Running HW Monitor, Processor Explorer, and Task Monitor running at the same time should not raise temps 20C unless your system has poor cooling and running anything should also raising the temps. Try other programs and see what happens.
5. Running Task Manager should not stabilize anything, it should just monitor.
6. Your over clocked but running any programs should have the same temp. effect. Remove the over clock for now.
7. Your computer could be infected by the use of Gadgets or other things.

-----------------------------------------------------
I would start by setting your bios to default. I would also make sure Windows is set to default. No selection of number of processor core running when ect. No over clocking for testing.
Remove all Gadgets. We need to know if your computer is clean.
You use Avast and Malwarebytes both good programs. I would run updated full scans using both programs. I would also run Eset on line scan to be sure.

Well as you can see I have just made a long post with my thoughts and suggestions. Seem I have been doing to much thinking.
Take a read through them just the same. It would make me feel better.
Changing user accounts should not effect your temps. It could of effected a infections ability to run using a new user account. A infection can still be hiding.
Because of your last post a over clock should not be a problem.

@Layback Bear

Thanks for such an in depth reply.

Much appreciated. I am away from my desk and I am weighing up doing another clean install following your suggestions.

Will inform you of any actions.

Cheers.

Update.

As it turns out, changing user accounts brought back the problem.

Bit the bullet and did another clean install.

Before installing, used diskpart.

Changed account name and password.

Installed Avast first then HW monitor.

Installed updates and 3rd party programs checking temps in HW Monitor during each install and application.

Did not install any gadgets.

I think SysInfo was the culprit (tho handy), as it is hard to find and I downloaded from a non reputable site.

System runs fine and idle temps are 25-30C.

Still monitoring.

Update 2.

I think I found what the problem was. It wasn't the gadgets after all.
