What make/model XPS laptop do you have?  What OS are you using?

 

Have you tried re-installing all your drivers?  Have you tried a 'System Restore'?

Hello 09,

 

If you want a solution to the problem please be more specific,as Fireball mentioned the specs and the model.

Also since when the problem has started ,is it after installing a particular update or SPack. 

What else have you seen wrong with the system is it just the device manager not displaying the contents.

Please go into the safe mode and check if the problem persists and if it does please try uninstalling the

 SP1 for Vista if you have installed it lately.

Sorry about that,I have a m1330,vista,I have tried system restore,it didnt help.It wont let me reinstall the drivers.Im not sure what to try next.

It "won't let you" install drivers?  Even in Safe Mode?

If not, you may have to resort to restoring the laptop to its factory settings?
If it comes to that... make sure you backup anything important to you first!

Ya not even in safe mode.Alot of my services are stopped and it wont let me restart them.I checked for registry errors,there are none.I checked for spyware,adware,viruses and there wasnt any.But one wierd thing was that my Trend -Micro pc-cilion kept updating over and over until I turned off the automatic updates.I have not downloaded anything but regular updates for windows.My computer keeps getting slower and slower,windows not responding.I have alot on this computer,and would perfer not to have to reinstall everything.So if anyone can help I would really be grateful. Thanks
