Hy, basically every now and again my computer would suddenly freeze with no signs of running and suddenly would go to a blue screen saying something like STACK_KERNEL_INPAGE_ERROR, this sometimes changes, but the more frequently this has happened my norton 360 wont start on start up anymore, my microsoft office wont start, i cannot install any windows updates, and the system folder in control panel wont start PLZ any help??

Oh, and Internet Explorer wont start, i am running Firefox.

If the blue screen saying something like STACK_KERNEL_INPAGE_ERROR is actually KERNEL_STACK_INPAGE_ERROR, then look HERE, HERE, and HERE. More precisley you will need to reproduce the BSOD in order to look up the second parameter that usually pinpoint the specific cause for the above error message. i_Xp/VistaUser

You can also find useful information by going to Administrative Tools/Event Viewer. The specific numbers will be listed under the particular event along with other possibly useful information.

Is there a step by step list that you could give me to try, you seem to know what your doin! i can follow instructions! cheers
