Computer CPU/Processor maxed 100%

Is your computer experiencing a CPU that is running at 100% Is your computer experiencing slow performance?

You can view your CPU utilization and other performance stats using Windows Task Manager. Press Ctrl + Alt + Delete and bring up Task Manager. Go to the performance tab.



The top of this screen should show your CPU stats.

In Linux you can use the TOP command,
Type the top command:
$ top

A CPU that is running at 100% utilization is not necessarily a problem. When the computer is booting up, or coming out of sleep mode, it may max out the CPU which is normal. The CPU will be utilized fully in order to bring the computer up as fast as possible. Some computers will even utilize the CPU while it is idle, to complete background task such as disk cleanup and file reallocation.

A problem will occur if the CPU stays maxed out. If it stays at 100% for more than a couple of minutes, you may be experiencing degraded computer performance.

Steps to reduce performance degradation.

-In a limited number of cases, software bugs can cause CPU utilization to spike. You will know this is the case if you are using a computer program(that is not hardware intensive like photo/video editors) and notice degraded computer performance. Check your CPU stats while running the program. If this is the case, check online for solutions and possible upgrades which resolve bugs in the software.

-You can reduce Windows start up programs, which will speed up the boot/wakeup process. You can do this from the MSCONFIG window. Go to Start > and in the run box type "msconfig". Go to the "startup" tab and you can uncheck which programs you do not want to start with Windows.

-A majority of the time a computer will get to a point were the hardware will need to be upgraded in order to handle the work you are doing. Common computer upgrades are memory, cpu, motherboard and hard drive.

100% cpu usage


In Task Manager, go to the Processes tab and sort by the CPU column. See what is hogging up all your CPU. It may be a virus, if so, I recommend downloading Malware Bytes and doing a full scan. Warning, it could take several hours to scan depending on the size of your machine. Good luck!

THE TASKMANAGER'S PERFORMANCE SHOWS 100% USAGE EVEN WHEN THE COMPUTER IS NOT PERFORMING ANY TASK.SPEED OF THE COMPUTER HAS BECOME VERY SLOW.


Start by identifying the processes which are using the cpu and stop them or disable the processes which are causing the usage.

My computer is really slow going into differnt sites....the compressor fan is slow to start up...had my computer stripped down and tuned up, but it's still slow...they said the cpu is showing its age, which is 5 years old......I love my computer..do I need a new cpu maybe...Thanks


Your computer going slow could be for the following reasons: 1 Not enough RAM - remove unwanted files by cleaning the disc. Also defragment the computer. Increase the RAM 2 Virus - remove the virus 3 If you do the above you will see the improvement and no need to have a new cpu

Slow Computer


Could be lots of reasons. First thing you're gonna want to do is backup your important files.

I'd say it's time for a format / re-install.

You could try figuring out the exact problem(s) but it's much smarter to do what I suggested.

Trust me.
