I've heard similar claims and using Grif's advice at http://forums.cnet.com/7726-6122_102-5509131.html?tag=posts;msg5509131 we found Conduit and too many other things.
https://www.google.com/search?q=APC_INDEX_MISMATCH finds folk have solved it but I don't see any machine details, mention of Norton so I can't slim this down for you. But at least it's a known fail.
I'm using Windows 7 Ultimate 64 bit. There was no problem few months ago, but nearly 4 or 5 months ago I started to take BSODs. I'm using this PC as a home theater, like a bluray, dvd player. So I didn't downloaded any harmful or erring program or software (I believe so..) except media players and codecs. I also changed its RAM with my daily use PC's, but it ended up with BSOD again. I also tried to restore system to another day (to June - 6 moths earlier and I'm sure in June it was working fine) I believe it's driver error because it does not occur in safe mode. Ah and I need to add this: nothing happens if you won't enter your account, no crash, no BSOD.
There are two types of error indicated in BSOD; Stop: 0x1E and APC_INDEX_MISMATCH Stop: 0x1. I don't know what trigger which one, but I don't get both of them in safe mode(also in safe mode with network)
I had no sound in safe mode, so I thought it might be sound card driver problem and disabled it. After disabling and rebooting PC normally, I got BAD_POOL_CALLER Stop 0xc2 instead. I think it is not the graphic card's driver because it is on-board.
I don't know what to do right now. I have no clue, nothing left in my hand
