High CPU usage in Task Manager

post #1 of 12
Thread Starter 
Hi guys

I made a post the other day about this but its still happening, when I open task manager my cpu shows 90%+ usage and drops to 5-10% straight away
I'm not gaming or using it at all, just browsing the internet
Watching youtube videos they start to slutter and lag because of this
I'm pretty sure its a malware or virus hidding itself when I open the task manager which some people have said
But when I check and clear malware it didnt fix it
Using stock cooler and not overclocking (temps show around 40-45c on all cores) (i5 4670k)

Any suggestions?

Thanks

Same OS in rig? Overclocked or stock?

check which process is using that high load

I really dont know the minute I open task manager it drops and when I look in processes just shows system idle process at the top

That happens to me too on my windows 8.1 laptop. Probably just a windows 8 thing.

Alright, so what I'm guessing is that your chip is still at base clocks, and when you launch task manager, it puts a load on the chip that takes up a substantial amount of the power the low clocked chip is at. It then clocks up high enough to handle loading in the task manager. I know it's a different scenario, but I see it all the time on my laptop. It's W8 with an AMD A8-5545m. Hits something like 85%, and I'll see the clock speed jump from 1GHz to 1.7GHz or so... and at the same time the CPU usage drops.

I think this is the correct explanation. I just realized opening task manager on even my desktop makes my cpu usage go up to 10-20% for a brief second and then back down to 0%.

It's not malware, adware, bad overclock or anything like that. It's task manager. It always spikes when you open it. Press ctrl+shift+esc and you'll see it spike up, then go down.

The amounts that it will jump to is determined by the current clock rate. If the clock speed is lower, then it takes more resources.
