windows task manager and Registry Editor ahhhhhhhhhh

when trying to bring up the task manager ( ctrl alt and delete) the window comes up for about a second and dissapears the same with the registry editor (regedit in 'run')
please somebody help me

 

If this is a brand new behavior, try reverting to a restore point from before the problem started.

Otherwise, specify Xp-home or XP-pro and the service pack level.

 

its xp pro

 

i restoed te pc and still no luck please help me

 

If you have the install CD, try
start~run~sfc /scannow

At some point if it finds bad system files or notices missing system files, it will probably ask you to insert the CD.

And unless your CD is XP-pro with SP1, you'll need to reapply SP1 after the sfc completes.

 

i did this and the same happened the window came up and dissapeared so what now
