Physical Memory is 72% when Chrome is open, and 40% when Idle.

Question

This is insane and I have tried a lot of things. First, I increased the virtual memory to 6000mb (custom). Then i disabled the windows effects. Then unchecked everything on start up using msconfig. Still, computer is 39-40% on idle, then 70% when in chrome.
I heard this isnt normal, but I had this computer for at least 3-4 years. I am not too good with computers, so extra guidance would be appreciated.

Hi,
To fix this issue, I would like to suggest you try the folloing methods:
Method 1 : Use Google Chrome’s inbuilt task manager
To bring up the task manager on Google chrome just press the following key combination ( Shift + Esc ). The Task manager in Google chrome shows how much resource every web page and each of the chrome extensions are using . Right click on any process
and you can select from more categories of information . If you find any of them fluctuating and using too much of your ram and CPU resources . Changes might be that the page is infected or the extension is malfunctioning . select the process / extension and
end it . do a thorough scan of your system for any malware infection that could have happened possibly .
Method 2 : Remove all the extension in Google chrome
Sometime one or multiple plugins can be the reason why Google chrome uses a lot of your computers resources . use chrome’s extension manager to find out which of the extension is using more resources . Select the extension and end it . Restart chrome and
if the plugin works normally then the problem is solved .
Method 3 : Reset chrome
If you can’t find any problem through the above steps then thy Resetting Chrome . It  fixes most of the problems wit chrome . Before resetting chrome , do sync your bookmarks and other data with your Gmail account so that you don’t lose them
If you follow these three methods then most probably your problem will be solved . If it doesn’t then uninstall and reinstall chrome.
I would like to suggest run Memory Diagnostic Test and check.
