Page_Fault_in_Nonpaged_Area due to nis

Hi,

 

I use NIS 2010.After an update   windows (xp professional ) constanly  restarts on  windows  logon  . I tried all modes ,use cd windows to  repair boot  sectors ,check drives ,   but nothing changes .It  says-   Page_Fault_in_Nonpaged_Area.

 

I think that norton  may have  stored some  data in the  nonpages  areas .I  am  sure that  the problem   doesn't  come from  ram or  hard  drive   .My question  is  how  to  deinstall norton ,  any  suggestions.

I  don't   have  an image  file of xp.

 

thank  you  in advanced
