Hello, I'm running Windows 7 on an Early 2009 Mac mini with 1 GB RAM. For as long as I can remember, my computer has seemed to experience a lot of BSODing on Windows. I've tried clean installing both XP and 7 while still receiving the error. It tends to happen randomly at totally different times; I've seen it happen waking up from sleep, in the middle of a game, and typing an address into Firefox. I think it may be linked to my bluetooth mouse and keyboard, but I'm not really sure as it's happened while away from both and just using my USB 360 controller. I've tried updating drivers from manufacturers websites, using only the drivers that come with the OS X install disk, nothing seems to work and it's becoming really frustrating. If anybody has any idea what could be causing these stupid IRQL_NOT_LESS_OR_EQUAL_TO blue screens, I would REALLY appreciate it if you could help me out. Thanks, KoNeko EDIT: All OS's I've installed have been 32 bit.
