It is normal to see in your Task Manger several to many svchost.exe Processes running at the same time.
It is abnormal for one of the svchost.exe processes to be running amok consuming large amounts of CPU.
Most of the time the CPU usage of the svchost.exe Processes should be around zero percent:
Under each svchost.exe process are important Windows processes and Services. Each svchost.exe process might be servicing or "hosting" one Windows Process or Service or several Windows Processes and Services. Unless you know what is going on underneath the svchost.exe Process it is best not to just end them from Task Manager.
As you can see here the fist svchost.exe Process with Process ID (PID) 700 is hosting these important Windows Services:
If you do end one of the the processes and your system malfunctions or becomes unstable restarting the system should get things going again.
You say when your system sleeps the monitor goes off but the fans keep running. So does mine and that sounds normal for Sleep mode.
Why do you think that is a problem?
That could be very normal since in Sleep mode the system must still have some reduced power and the fans could be those in the power supply or on the CPU cooler (if there is one). The CPU and other parts of the system are still "running" in sleep mode and it has to be running in order to detect the mouse click or keyboard stroke that will wake the system up. In other words there may not be a problem at all.
Do you think the system used to behave differently?
If the system used to work differently what do you think happened to it?
If you think there is a problem you need to tell us more about your system.
Is your system a laptop or desktop (we'll find out with the other questions).
What is your system make and model?
If a Dell system what is the Service Tag number?
Do this so we can see what you have:
Click the Start button/orb in the lower-left corner of your screen. Or, press the Windows logo key on your keyboard.
In the search box enter:
Select/click msinfo32.exe and the System Information dialog box will open.
Click on System Summary, click Edit, Select All (Ctrl-A), Copy (Ctrl-C) and then paste (Ctrl-V) the information back here in your next reply.
For video driver information, expand the Components, click Display, click Edit, Select All (Ctrl-A), Copy (Ctrl-C) and then paste (Ctrl-V) the information back here.
There will be some personal information (like System Name and User Name), and whatever appears to be private information to you, just delete it from the pasted information.
