Hello,

Thank you in advance for any help given. I was on the hijackthis thread and was given the all clear sign.

About a week ago my computer slowed down considerably.

I deleted explorer.exe through the task manager and lost all icons and taskbars. Now when we reboot all that appears is the background. I can access IE or Firefox through the task manager and then about 5 minutes later the icons and taskbar appear. I tried system restore and that did not work.

Once a browser is open the internet works fine.

Double clicking an icon on the desktop ( when they reappear ) takes about 5 minutes to open.

Again thanks for the help!

All the Best,

Frank Williams

Try opening Task Manager, clicking on the Processes tab, then clicking on the View menu. Then click on Select Columns, and then put a check mark in the IO Reads box. Then look at the processes to see what's consuming the most memory, the most CPU, and the most IO Reads. Also let us know if it's a lot higher than anything else (that'll be the clue that the problem is with that process).
My browser caused a flood of traffic, sio my IP address was banned. Hope to fix it soon. Will get back to posting as soon as Im able.

Svchost.exe is a generic host process name for a group of services that are run from dynamic-link libraries (DLLs). This is a valid system process that belongs to the Windows Operating System which handles processes executed from DLLs. At startup, Svchost.exe checks the services portion of the registry to construct a list of services that it needs to load. It is not unusual for multiple instances of Svchost.exe running at the same time in Task manager in order to optimise the running of the various services.

A common cause for a spiking CPU can be related to the MS update package and Windows Installer (MSI).

...The Svchost.exe process may spike the CPU usage to 100 percent during update detection or update installation. Also, the Svchost.exe process causes the computer to stop responding for various lengths of time...The Svchost.exe process produces an access violation during update detection or update installation...

To disable Automatic Updates do this:
  • Go to Start > Run and type: services.msc
  • In the list of services, scroll down to "Automatic Updates"
  • Right click on it and then click on "Properties"
  • Change Startup Type from 'Automatic' to 'Disabled'
  • APPLY the change and close the window.
  • Then Reboot and see if you still have automatic updates running.

Try using this free utility to find out what's running underneath that svchost.exe process: http://www.microsoft.com/technet/sysintern...ssExplorer.mspx When you hover the mouse over it, it'll reveal some file names. Be sure you have the correct svchost.exe process and we should be able to suggest some fixes.

BTW - System Idle Process is just your system "idling" - so high numbers there are a good thing.

If I may ask, why are you running SQL Server on your system? 17% will slow the system down - so it could be the cause of it.

If the IO Reads aren't all that high, then it may mean that the issue isn't with the hard drive (a major source of slowdowns - either because of hardware problems or program accesses). That leaves the rest of the computer (generally all solid state and no moving parts to slow stuff down).

Also, what are your system specs? If it's a store bought PC, the make and model will be enough - if it's a custom built system, then we'll need the processor, hard drive, RAM, etc.

How many processes are running in Task Manager (in the lower left of the window)? Try clicking on the Performance tab and let us know what the numbers are there.
