Windows 10: Cpu usage will not go past 26% utilization and .85 ghz

I have an rx 580 , i5-6500 , I recently bought another i5 6500 and it is still peaked at 26% utilization and .85 ghz , I also just changed it to high performance and my cpu has only gone up to 37% and 1.18 ghz nothing more nothing less. any help would mean the world to me I need my computer up and running for school

CPU frequency locks at 0.78 GHz

Hello,

My CPU get locks at 0.78 GHz and not going up or down. In the same time when CPU is locked at 0.78 GHz,

laptops fans runs fast (noisy) but the coming air is not even hot.

I have found a tool named Intel(R) Extreme tuning utility to use it as monitor of "what's going on with my system",

i'm not overclocking or changing something in CPU.

Tuning utility shows value of "Thermal Throttling" as 100% i think this is the reason why CPU stays at 0.78 GHz, it get down step because of this thermal throttling.

CPU package and core temperature is normal around 40c .

All this information is visible into this picture:



With random combination of reboots, shutdown unplug power and plug power CPU gets frequency stepping again

Thermal Throttling is becoming zero and fans stop... and everything goes normal.

Can someone explain what is connection between Windows (10) OS and CPU freq. stepping.

I think there is some connection because of available options in power plan settings, there is options Processor power management

that can control CPU min and max freq. state, but i'm not pretty sure is it related to "Thermal Throttling".

 

CPU won't go above 23% utilization

I have a custom built PC. specs are below. After some recent problems and a full windows reinstall it seems that my CPU won't go above 23% utilization. I have set the power plan to high performance and am using Prime95 to attempt to stress the CPU. When
I look in the BIOS everything looks correct. The CPU temp is reasonable, it detects the CPU as 3.4ghz. Windows also detects that the model of the CPU is correct and lists it as 3.4ghz in system properties. When viewing the CPU on the performance tab of
task manager is lists the speed as 0.78 GHz and that number never changes. It's like it's stuck on that number. Any help on how to troubleshoot this problem would be appreciated!

CPU: Core I7-6700 @ 3.4ghz

Motherboard: Gigabyte GA-H170M-DS3H

Bios Version: F22e (latest)

Graphics: Onboard Intel 530

RAM: 16gb DDR4 2133

PSU: 550w

Power plan: High performance

Edit:

Additional Troubleshooting steps:

Reset BIOS to default values - Issue still occurs.

 

HP EliteBook 2530p forced shutdown automatically due to high CPU Usage

High CPU usage -- even 100% CPU usage -- shouldn't in itself cause a shutdown. However, if the computer is running at 100% CPU usage for any significant length of time, particularly if the vents are blocked, either physically or by dust accumulation, the
CPU is likely to overheat, which will cause a shutdown.

1. Open Task Manager, select the Processes tab, and click the button to "Show processes from all users."
2. Click "CPU" in the header row once or twice to sort the entries in the order of decreasing CPU usage.
3. Create the situation where you have 100% CPU usage
4. List the "Image Name" of the top 5 items in the list together with the indicated CPU usage for each.
5. As soon as you have noted the values in Step 4, right-click on the top item and select "End Process."; repeat until CPU usage drops to a more reasonable value.

You should also download one of the following free utilities and monitor the temperature of your CPU and system:
