Crashing with Multiboxing.

[Goliith]

I recently came into having the resources I needed to be able to Multibox WoW without feeling guilty about doing so. I spent a few hours researching scripts for AHK and learned how it worked, a few hours later and I had a functioning script that did everything I needed it to do.

Fast Forward a little while and I have 5 accounts, and am excited as hell to finally getting to multibox (Having been 'old schooling' it by Dual Boxing with /follow and playing both characters by hand for years now)

But wait! A giant ass bear has spawned and is blocking my way to glorious solo experiences.

Running all 5 accounts at once at first was no trouble, started them all up and was just controlling one, walking it to the spawn location of the other bots (It having been a Night elf, the other 4 Draenei) All was good! But then out of no where, right after all 5 characters met up, my computer bogged down to almost 0 activity, my Processor sky rocketed to 100% use and everything stopped responding. Needless to say, a restart followed Shortly thereafter.

Fast forward again and I've lowered all the video settings to absolute minimal, and start all 5 WoWs up again.

System failure again.

All following attempts to run 5 accounts at one time end in system lock up.

Getting very frustrated, I decided to try and just run 4 accounts, as before, everything was fine and dandy, this system would go to shit the moment the 5th account logged in.

about 10-15minutes of getting macros set up and UI's organized and I get to kill a few mobs! System crash.

I've been trolling and searching the forums here to try and find some help on the issue, but all attempts failed so I decided to make my own post, in what is very possibly the wrong section.

My PC should be able to run 5 copies of WoW on minimal settings without any hint of a problem, Hell I get 900FPS with only 1 copy running on lowest settings.

PC Specs:
Motherboard: Asus Crosshair IV Formula
CPU: AMD Phenom II X6 1090T (6-Cores)@4.15Ghz(3.2ghz Stock)

Hopefully someone out here has an idea as to what the issue is...game time is ticking away D:

PS: The game is at 1920x1080, though running it at...1366x768(I think that's it) didn't change performance one way or the other.
