Hi Direwolf,

 

Welcome to Lenovo Forums.

 

Open "System Configuration". (Windows + R), type in "msconfig" and press OK.
Under "Boot" Tab click on "Advanced Options" and check "Maximum Memory" and select 8192.
Press OK and Apply.
Reboot.

 

Let us know how you get on.           

Regards,

Shashi

Make sure you are using a 64bit OS installation and post back as this makes a big difference in troubleshooting.

 

Thanks

Re: Lenovo G40-45 Ram usage error

I would check on Page File settings and also how much memory is being reserved for video use.  Those are my two top ideas.

 

Good luck.

Hi Direwolf,

 

In addition to CB, I would suggest you to refer to the link and run the Memory Diagnostics Tool:

Re: Lenovo G40-45 Ram usage error

I would open the Task Manager and see how many services / process is running.  When you use Ctrl+Shift+Esc it will open the app, and should be on the first tab.  On the bottom you will see a button saying "more details" and when you click on it you will see an expanded view of running and background processes.  If it is more than 60 or so you may have to prune out some un-needed services.  Also - check the performance tab to see what your memory usage is, how much utilization is showing.  You can get more details by clicking on the "Open Resource Monitor" link on the bottom of this tab.

 

Also - a nother good tool is Process Explorer as it is the Task Manager on steriods... Shows a good deal of information on running processes and allows them to be suspended to evaluate results.  Google it and download from MS Tech Net if available.

 

Good luck.
