svchost.exe (netsvcs) is using the most physical - causing extremely poor performance

I have a Dell Latitucde E5540 laptop running Windows 7 Pro with all the latest updates. It has 4 GB ram
- its been scanned for viruses and Malware and came up clean

Problem I'm having its that it performing extremely slow where at times I cant open a documents of if a document is open, I cant type or whatever I type finally catches up and enters the typed charactors
- I disabled the MalwareBytes Premium I run
- Ive shut down all applications and web browsers.

- I checked taskmanager and found Cpu resources are very low near 0%
- the hard drive indicator light is totally solid
- the memory is maxed out to 3.8GB (my system normally never usese this much ram)
- Resource monitor shows that"svchost.exe (netsvcs)" is using the most physical ram. 2nd biggest user is "MsMpEng.exe" (which is Windows Defender) Most likly the biggest issue is "svchost.exe (netsvcs)" Process Explorer doesnt really help me. Maybe I'm not using the tool correctly

I disabled the MalwareBytes Premium

If I reboot the laptop, its fine for a few hours then goes back to these issues

What is a good tool to use to determine whats actually using the most ram and most interstingly, the hard drive being fully taxed at the same time the RAM usage is maxed out?
- I'm running the Microsoft Security Essentials. "Windows Defender" is turned off because I'm running MSE (I know in Windows 8, its actually the same as MSE)
- Im just wondering if MSE is part of the problem

MsMpEng.exe is part of MS Security Essentials.  This reference explains how it may be causing the high CPU usage problem and how to fix it.

You should not run MS Security Essentials and Windows Defender on the same Win 7 PC.  Uninstall Windows Defender.  It is not effective on Win 7 PC's, but can cause conflicts with MS Security Essentials.

svchost.exe is usually not the problem of high CPU usage by itself.  It is only opened by the other processes it is "hosting".

Correct, I'm having a difficult time using process Explorer to determine process under the SVChost.exe that is the culprit.
Did you have any success following the procedure in  ?

Did you read the instructions for Process Monitor?  The first image shows the CPU usage for each process.  You would look under each open svchost.exe and ignore the other processes.  
However, you seem to have defined already that MsMpEng.exe is the process using the CPU.  Perhaps uninstall and reinstall  MS Security Essentials.
It was not the MSE. It still happens. I'm somewhat familiar with the Process explorer but I could determine which process under the particular svchost.exe. I eliminated Malware Bytes as well thinking it was a culprit

I see this on so many PC's where the svchost.exe (Local something or netsvs?? that using all the ram and possibly the drive activity.

Narrowing it down is the difficult part which I have been successful with process explorer
I'm running into this more and more often. Using Process Explorer shows what svchost.exe is running but it doesn't shoe which process under svchost.exe is using the most ram, cpu or disk activity. If it does, then I'm definitely doing something wrong

I appreciate all your comments in this post.

This has been difficult to pin down what process under the several "svchost.exe" that normally run. With all my experience with this, it appears to be the executable that has the most processes running underneath of it. I don't see a way to define which of those several dozens of processes that is causing the high utilization. I could very well go to msconfig and start shutting one process at a time down but it's way too time-consuming. Were going to end up just rebuilding the PC
I was not able to resolve the issue. Sometimes you just have to bite the bullet and rebuild the operating system.
The posted suggestions were good suggestions and I'm sure would have worked if narrowing down a different Windows process
