MapleStory and BSOD

First time I've ever actually received this blue screen, but Maple has been frequently crashing my computer upon exiting. Now, it finally tells me the exact problem and points to EagleNT.sys, a file linked to HackShield. In all other cases, my computer merely turns itself off and then reboots.

I am currently re-installing MapleStory in hopes of that resolving the issue, but I also have Combat Arms and Dungeon Fighter Online installed, which both use HackShield as well. I have never experienced any crashing issues with those two games, but I rarely ever play them in the first place. The issue most frequently occurs if I double log, and attempt to exit the game on one of my secondary accounts, presumably when HackShield attempts to unload; however, I have experienced the issue off of a single instance on my primary user account as well, and on the reverse have experienced logging multiple characters with no issue upon exit. In the event that this does not resolve my issue, does anyone have any information as to what to do? I am led to believe that there may be a connection with my graphics card, as I do not believe this issue occurred at all until I installed my Radeon 5770, but those drivers are constantly kept up to date. I find this a severe issue as if my internet connection were to ever disconnect randomly, my computer would be met with an untimely reboot should I have MapleStory open. Thankfully, I do not have a shop at the moment, and I have recently upgraded my internet connection, but it still stands as a threat.

I am running Windows XP SP3 kept completely up to date as far as I know, by the way.
