Cpu % spikes due to a bad app?

JamesJoanne · 23 Jul 2017 at 03:43

Something is causing my cpu at random intervals to be utilized 100% and this sort of locks up my mouse etc.
I can see the sudden spikes but I can't see which app/service is causing it as various changes are occurring at the same time on that task manager window.

Is there any app that can tell me which app at times is using so much power? In way that you can pin point to it easily.

Cheers all!

This seems to be the same as what's in the task manager. It doesn't really pin point to me whats the application that freezes my mouse

+1 have you tried it out ?

you get a historic cpu usge graph, so can see trend, can track cursor back and it will show name of biggest cpu% process,
can then monitor/create curves for individual processes, and see threads of that process(helps nailing services),

can also then create a windows performance monitor for individual processes, to trigger events when they behave badly.

it pull down each .exe into multiple workloads and shows you whats inside svchost.exe

its not the same MUch more indepth.

if you have 40 running processes it will show you a good 200

its used by microsoft to debug its much more than task manager....

Well am not impressed. At the same time maybe am being thick.

Something is driving my cpu usage to 100% but i can't make out what it is. I do watch the graph and processed like a hawk and I can't see what it is.
When I hover the mouse over the red portion of the graph I only see "System 4" all the time. I look at the detailed view over at the panel and I can't see which process is causing the problem

Is there a program that can pinpoint to the service that is going crazy?

if it is the system process , that is the kernel for the OS, and per a guide like, below
https://superuser.com/questions/527401/troubleshoot-high-cpu-usage-by-the-system-process
maybe a driver that is causing it eg network/wireless/usb

when did problem start ? what changed, did you have a windows update ?, you maybe able to roll back before the change.

https://www.tenforums.com/tutorials/5472-view-windows-update-history-windows-10-a.html may tell you which drivers changed

Did you google people using same system

back to basics, check the event log for errors

and what is your system specs

Thanks for the links jpaul. I managed to find the culprit and it is BitDefender. As soon as I disabled it, it stopped locking up my system.

in that case i would seriously consider you check your pc for infections. if Bitdefender is using so many resources it must be protecting you from something...
