Charlotte,

A BSOD can be caused by virtually anything on your computer from hardware, drivers the operating system or software applications. However, more than 95% of BSODs are caused by application software.

I determined what was causing my BSOD by eliminating all of the hardware components, and then started on application software starting with freeware first. As it happens the cause was a freeware program.

I think that I would uninstall Maple Story first. With all of the reports on bad behavior, this program could be in some sort of loop, which is making your hard drive do constant searches (or whatever), and this is creating the noise situation.

Anyway, if that solves your hard drive noise problem, then go ahead and proceed with uninstalling Norton.

Cheers,

Linda
