CPU% Very High Google Chrome Issue?

Old dell xps 15 9550 laptop

i5-6300hq processor

32gb ram

1tb nvme ssd

windows 10 pro


I had mentioned a while back i upgraded this laptop with the new ssd and ram and it started to be faster.


I use chrome and have tons of windows/tabs. Example imagine 6 tabs... but each tab could have 8 windows each etc. It could be more or less.



I then noticed when i was on chrome... the cpu was very high... it spiked to 100% and stayed there for a while... dropped down a bit... but always seemed to go back to to 100% etc. The only time this usually happens i notice is when i do the windows virus scan though


I then restarted my laptop. The cpu when nothing is opened is under 5% usage. As you know when you open chrome... i have it always open from the last saved page etc... it would always spike up to 100%... since well it would open like 50 plus pages sometimes through all those tabs. But every single time though... it would drop all the way back down to 50% or so... but it would not go higher than 80% unless i try to f5 many of those pages at the same time.


Now what i notice was... it kept going back up to 100% in cpu. But not only that... when i check task manager... you see how they have the


google chrome (80) ... the number in the parenthesis... is that how much chrome tabs you currently have opened? Because i notice that number is never right whether i have 20 tabs or 50 tabs or say 100 tabs. But not only that... it kept going back to 100% cpu each time. I then decided to close many of my tabs and only have like 2 or 3 tables... which totaled maybe 20pages. Now... it showed google chrome (101) all the way down to only (80)... which makes zero sense at all. Does the computer think i have 80 tabs opened or something when its no more than 20?


I then decided to close 2 more tabs... and only have 1 tab... and only like two windows on that. Then the cpu drops all the way down. Anyone can tell me why im having these issues?

 

Right now i have 3 google chrome windows opened... total tabs on each are 2, 6 and 3... so total 11 tabs total.


But on task manager it shows


google chrome (20)



Can someone explain why that shouldn't show (11)?

 

Since no one can see your Desktop that would be akin to "Looking for a Needle in Haystack" question. No two problem act or look the same or results from the same problem because of varying users hardware and software setups. Have you tried to look at Google Chrome support FAQ to see what they say about this? I do know from FF experiences when the Browser gets corrupted from either updates or user caused updates this can lead to High CPU usage as well-the fix is to uninstall and remove the browser folder and reinstall to get rid of the problem and in the case of FF that is what fixes the corrupted updates for FF. But as anything without someone looking at it in person this is a waka-mole problem.

 

Try Opera or Brave.

 

The only thing I can think of is there's some script going rogue in one of your open tabs.

 

Is the O/S Dell OEM factory?
