It could have helped, but in my opinion the fact that the daily BSODs have stopped [...perhaps only for now...] is more likely to be co-incidence considering that you still have the BSODs with the TV guide. Given the nature of BSODs - particularly their relationship to specific hardware and their semi-random occurrence pattern - I think it's likely that the same hardware or driver fault that was causing the earlier daily BSODs is the same fault that is causing your new TV guide-related problems. The only thing that's changed is when the BSOD occurs... and like I said, BSOD occurrences are semi-random in the first place.I think this may be coincidence... or at least, it certainly has nothing to do with your ATI tuner cards. Using/opening/browsing the TV guide doesn't use the tuner cards. However, that action will use your system's CPU, memory (RAM) and GPU. If simply opening the TV guide is enough to trigger a BSOD, I'd suspect a problem with the CPU, memory or GPU... or perhaps the power supply, or even the motherboard itself.If you're able to perform recordings as the first statement implies, I think it's highly highly unlikely that there's anything wrong with the tuner cards.To me this seems far more relevant than anything you've previously said. Running the CPU and GPU like that means you're effectively always stressing your system. Over time you'd expect components to wear out faster, and over-heating is always a possibility.Surely the information you've found in the system event log can help point you towards the cause???...or if not, you can use tools like memtest86 and prime95 to test the stability of your system's memory and CPU respectively.</blockquote>
