I seem to have fixed the problem with my PC I know have a problem with my cheap nasty laptop that is going to go out of the window anytime soon.

The problem I have is two fold ..Firstly when I turn my laptop on I get an exe file called
svchost.exe system using all my cpu. If I kill this it gives me back my cpu but i am not sure what damage Iam doing. I have searched the net and attempted some of the answers but nothing seems to stop it when i reboot it justs restarts again.

Secondly which iam not sure if it is connected  but my wifi keeps dropping out. When I start the laptop I get 54mbps and strong signal strength the next minute either the mbps drops to either 1 or 24mbps or the signal strength just dissapears.

I have plugged in a ethernet cable and after killing the svchost.exe my internet seems to run fine, I have also installed a new wifi card. Sorry for the long story.

svchost is a generic wrapper for any process that chooses to run under it. So it could be a legit process, or a non legit one.

Wifi is always flakey on slow machines, esp as you crank up the encryption.


As I've said before. Rebuild it, see what its like then. I guarantee it will run faster, esp if its shitty XP.

+1 ..

before rebuilding it dont forget to note all your device name-models and check your drivers..

 renewal of system kernel will make things different..  and also download your wifi device driver again..  if a new version exits use it..

Thanks for advice but wouldnt know where to start.

first open computer management then device manager .. note all devices and their types..

then find your system installation CD and driver CD(s)

put the CD in and boot from it.. (if it doesnt , arrange the boot order from bios)

Or just run the Belarc Advisor freebie tool, for the lazy amongst us

For me rebuilding is a last resort - you lose every bit of software and every device driver you have ever installed after day 1.  Rebuild can be quicker than trying to find the problem though .  It is also more certain of a result.

Instead of a rebuild you might try, in order of ease
* running a full virus boot scan
* leaving laptop running for a while to see if the problem reduces - it may be index scans
* If XP press start button, type "cmd" in the search box, in the black window that opens type "tasklist /SVC" this will show you all the processes running under svchost.  Look for any odd ones.
* If Vista or Win 7 its much easier - start the task manager, on the processes tab, click "show processes from all users", sort by CPU (click the CPU header), find the process using all the CPU, right mouse click it and click "Go to services".  This will show you all the processes using the rogue svchost.  Pick any service there you don't like the look of, right mouse click it and click "stop service". See if you system speeds up or stops.  Repeat until the former. Once you know the problem service you can permanently disable it, assuming it is not essential.
