I have an acer 5750g laptop with the core i7 2630QM cpu

I started noticing that my YouTube was lagging today. I think it has some time now, but i haven't noticed it before. So i checked my task manager where my CPU usage jumped from 20% to 40%. it has never done that before. I am used to getting around 3% to 5% usage. And between 40% and 50% in some intensive games. And now while i'm writing it stays between 15% and 20%. And if it is important my CPU runs around 45 Celsius which is normal.

Do any of you guys know what may be the cause?

Hi,

Adobe flash player is crap right now. I think it the main problem.

Yeah, you may be right there. Because i notice whenever i am doing anything on any random site my cpu usage spikes. especially on http://iwantmoar.com where i notice it the most, and it is entirely based on flash. And thanks for clearing that up for me. i thought there was something wrong with my cpu :p

Have you run a virus scan...use malwarebytes as it gets most of the virus programs that some more popular anitivirus programs miss.

Which service is hogging up your cpu when you open task manager?...since you are seeing this issue while browsing, check if it is the COM surrogate service which is engaging the cpu.

as for your temps, they are fine.

don't worry about that for now. first tell us which service do you see utilizing/engaging the cpu the most when you open task manager.

Yes that is a problem with Chrome that I've been facing as well. But you are looking under the "processes" tab...look under the "services" tab. Does something like dllhost.exe seem to be the culprit?

There is nothing under services which was called anything like that. But just to add some information. like a week ago my chrome was locked and it popped up a site where it said i had to pay a fine of 150$, but i found out it was a scam "you have to pay with ukash or paysafe" haha. Do you think that may be the problem. maybe that someone infected my chrome with a virus?

very likely...I could not figure a way out and eventually removed Chrome and went with firefox.

but since you do not see the processes or services I talked about, thee might be some other issue as well but I have seen these symptoms before and it usually is the dllhost....also there is a "show processes from all users" button at the bottom left of task manager when you click the "process" tab. do enable that and check usage.

I did what you said and that dllhost.exe popped up in processes in like a second and then disappeared.

then it is the normal behavior...suggest that you reinstall chrome.

I thought i would try using firefox before I reinstalled chrome. And firefox did the exact same thing. i loaded up a new site and cpu usage pops up at 30%. I'm really confused.
