So I got this process in my Task Manager that eats up my processor to about 57% but when I open the task manager, it drops to 12%. Avast and Malwarebytes full scan was not able to find anything. I already tried the steps provided upon google search but all of them are outdated. Please help, I love my rig. :(

Download Process Explorer from here:

https://technet.microsoft.com/en-gb/sysinternals/bb896653.aspx

That will replace the clunky Windows Task Manager for something a lot more useful. Also, it is Microsoft approved (notice it is hosted from a MS site).

Once you have that, take a look at the process tree and their CPU usage (you can sort by CPU usage as well). Get a list of the processes that actually consume a lot of the CPU time and post it back.

Also, it is a great idea to set up the "columns" for PE, because you can add the name of the owner, command line and other misc stuff about it.

Cheers!

Hey Yuka, thanks for the tip. I agree that this is more informative than the stock Task Manager. I might not be able to find the culprit because whenever I open that app, or even Task Manager, the task that consumes a lot of processing power suddenly closes. If there is only a way I can have a logger of the all the processes that opens and closes in my PC, I might be able to find it.

Then leave it open all the time :)

If it ever pops up, it will show in PE. If it doesn't, then you have a workaround for your problem at least :p

Cheers!
