I've recently been having problems with BlueScreen errors on my Windows 7 x64 system. The system itself is brand-new, being less than 3 months old.
My first one came up randomly and was listed as MEMORY_ERROR. I've ran Window's memory test, as well as memtest, and those results came up clean. In both these cases, I thought that World of Warcraft's out-of-date addons were the problem (as I've only ever gotten these with WoW running), but compared with a friend of mine who runs virtually the same system as mine (including the out-of-date addons) and have found no problems there so far. I've tried analysing the minidumps with Whocrashed, but to no avail.
Just earlier, while playing an mp4 video file, I also experienced the NTFS_FILE_SYSTEM BlueScreen and also analysed it with Whocrashed, but to no avail once more. I have reason to believe with reasonable certainty that it is not one of my hdd's that are giving me trouble (except, possibly, my external -- Windows complains about it having some errors when I plug it in, but nothing of the sort has ever happened before).
The last bit of software that I've installed was Comodo Internet Security, having switched over from Kaspersky Internet Security. With KIS I experienced none of these errors, and am now inclined to think that it may be CIS causing all of these BlueScreens. My system is stable to my knowledge, as I use it frequently in modelling computationally-taxing problems and thus is able to maintain long up-times.
I have attached the relevant minidumps and would appreciate it if anyone could perhaps analyse them further so as to give me an idea of what is going on.
