100% CPU usage makes laptop super slow?

1. Try to Restore to a point before any new software was updated.

2. Check Sysinternals for the better Task Manager which shows you which drivers are killing your CPU.

3. Reinstall Windows.

This isn't normal and should be easy to fix - it's most likely a driver pinning the CPU.

There are a several reasons why your computer is freezing/slow. First question is when the last time you cleaned your registry. Having a corrupted registry can cause a whole host of errors and problems. Freezing up is one of them. If you have a lot of unnecessary registry keys that are hogging up your computer resources. Your computer is bound to choke. Scan your registry with a good registry cleaner. If you pull up more than 20 errors or duplication, clean your registry.

2. Depending on your RAM specs and your computer usage. This could also be the issue. Having an insufficient amount of free space does not allow your RAM to function properly. If you are using a lot of RAM by net surfing or other activities without enough empty space your will get freezes. You don't need to buy new RAM but you should increase your free space by removing unnecessary data and perhaps increasing your virtual memory. The below link will show you how.

3. Spyware could be the culprit, so do a scan and see if your computer is infected.

4. That last area is a hardware driver. This could be the problem if new hardware has been added to the system. So, the drivers should still be up to date. So try the first two suggestions and see if you can get your computer to stop freezing/speed up.

Check your drivers. Hope this helps.

You should definitely scan for spyware to make sure your computer is not infested. This can cause mutiple programs and process to be loaded into CPU access and RAM thus making your CPU usage high. However, you should monitor it to make sure that the spikes in usage are temporary or constant. Constant would indicate a virus. Monitor it by pressing Ctrl-Alt-Del. This brings up the task manager. Check out the link below to see visuals.

Here are some ways to cut down down on CPU access

Disable the amount of services running in the background-- You can do this by altering your computer configuration. Here is how:

1. Open your Start menu.

2. Click Run

3. In the command screen type "msconfig.exe"

4. In the "system configuration utility",click either "service" or "startup" tab

5. Uncheck all programs that your are no longer using.

6. Click "OK"

If you haven't cleaned your registry in a while. This is necessary. Your registry holds all the information regarding updates, installs, un-installs etc. Each one of those events has

a key. and that key need your PC's resources. So, if you should clean this up. Do a registry scan if you got more than 20 errors you should clean it. Also your Operating System will constantly try to fix these errors which cause spikes in CPU access.

You should also check to see what programs are running in your task manager. If you see a program like svchost.exe. You may need to clear this program in order to return your computer back to normal CPU access time. There are several ways to do this. Here is one of them.

Hope this helps!

Sounds like it could be a virus, or you installed something that uses all your resources. When you look at your cpu usage, you should be able to see what process is using what resources. Check that out and report back.

Open your Task Manager (CTRL+SHIFT+ESC) and look at the application taking your CPU. It migth (or might not) be your anti-virus.

Once you've identified the process taking your CPU, look at discussion forums (through Google) and try to see if it's a virus or a known application "bug". A patch could fix the problem.

Good luck!

cpu usage does result in having a slow computer, but it is VERY odd to have 100% cpu usage for a period of time. for me if it does go to 100% it just shoots back down, but for it to stay there is very weird

RIght Click on the start bar and select Task Manager, click on the Processes tab and see what process is taking up so much of the processor, find out what the process is and see if it needs to be running.

Turn off all uneeded programs running in the background. Worked for me. Use a program called cCleaner. Go to startup and siable all unwanted programs. Also, you can run the cleaner and clean you system of all the useless junk.

I have the same problem but looking at the active processes, none of them show any useage (other than occasional iexplore at 3-5%).
