[jociels]

Hello. I am new here...
I keep getting these errors "Host process for windows services has stopped
working", and there are pop up windows that says 'BN... .tmp', DEP. I have
to stay on the computer coz if I leave it there's too many errors that says
BN...tmp. I have to close them or the computer will stop working. My task
manager is not greyed but when I press ALT+CTRL+ DEL it says
C:\Windows\System32\vdmdbg.dll, and I cant find 'gpedit.msc'. Pls help me.
Thanks in advance!
