Hi For the last few days, I've had problems with Windows 7 crashing, giving me BSODs with various error messages. I've attached 2 dump files, although there were more before I used system restore (which didn't do any good). Aside from the zipped dump files, I've also had DRIVER IRQL NOT LESS OR EQUAL & PAGE FAULT IN NONPAGED AREA. But from what I've seen, it seems to be ntoskrnl.exe that crops up most of all. The only new thing with my PC is a media switch box that I can plug in my wii, vhs and PC into, that allows me to play each of these through my monitor and speakers. But this has been set up a week before the troubles started, and it would surely not affect the PC anyway? I have tried to sort it out myself using the guide that is posted at the top of the thread, but it seems to be beyond me. I've put as much of my computer spec on my profile as I know, but if you need to know anything else, just ask and I'll try and find out. Thanks, Mike.
