Thanks for your quick responses.
It is extremely slow when starting up, it takes forever.
No I have not made hardware upgrades.
The Programs that crash returning the Inpage Error are Internet Explorer, Windows Explorer, Norton AntiVirus and some others.
Also if I try to open or delete files within the "Internet Temporary Files" Folder with any program that program will crash giving me the same Inpage Error.
I do not really know if the problem of slowness is related to the Inpage Error because actually the slowness of my computer is a problem that I have had for a while now whiles the Inpage error is recent.
