server pack 2 vista

Problem with Maplestory?
So I play maplestory with my free time.
I use vista, which is not recommended.
And my friend tells me to use windows XP (server pack 2) compatibility mode. So I do. And everything is fine till a couple days later.
I go to run maplestory, and I get a blue screen of death saying that a needed program or something has been terminated or malfunctioned. Or something like that :P. Can anyone attempt to help me?
The BSoD occurs when your computer has a problem in the physical memory (RAM).
