Usually everytime i bot my char, it takes bout 5 hours for an error to pop up and a blue screen that freezes my wow and honorbuddy and exits outta it. Also my hunter decides when he is in melee combat instead of running back and turnning around and shooting, he just turns around and runns and stays turned around so my pet has to kill it but he dies almost everytime due to more then 1 mob.
If you are getting actually Blue Screens... please write down your stop code and either post them here or look them up. It most likely has nothing to do with HB other than it may be excersizing what is failing (a driver, a piece of hardware, some memory as Kick mentioned)... You should write down the actual verbage (listed in ALL_CAPS_AND_UNDERLINES) as well as the stop code (0x43ACF000) and then the 4 other codes that are similar to the stop codes... just write down the ones that aren't all zeros...
yeah, i kept getting bsod's when i first re-built my rig ... windows kept adding it's own drivers before i could add the ones that i wanted; So of course i went into safe mode and delete their drives, added mine and the issues went away sometimes when i take out a memory card / usb device before i 'eject' it from windows... i'll get a bsod, but that's on my laptops (i don't do anything on my main comp except develop)
