Well, If you followed my other thread with my numerous crashes, you'll have an idea of what I'm going through. I finally broke down and purchased a new video card, as I felt the old one was suspect. I've gotten 2 BSOD's since I installed it yesterday. One was the infamous PFN_LIST_CORRUPT, and the other is a IRQ_NOT_LESS_THAN_OR_EQUAL_TO. None of the crashes are showing any events in the event viewer. If you haven't seen my other thread, I've already replaced: Processor Motherboard Memory (4 times) Video Card Any help with this before I toss this system out the front window would be greatly appreciated. I've been chasing this problem for months, and have replaced just about the whole system. Any help would be greatly appreciated. Here are the zipped files.
