I'm asking because I truly don't know, it seems to me that would be caused by some other type of issues? I ask because at the moment I just finished a 12+hrs Prime run (blend test with no errors) along with many different 3D Benchmark runs which also ran with no problems so I want to somehow test for the issues you mentioned above (but I don't know how to "install/uninstall assassin's creed from an iso on disk, do that multiple times in a row (5 times at least))? I also don't know what a "crc" is but I'd like to know so I can test for it. Is there any pre-made benchmarks that tests these things on a whole (like Custom PC's downloadable benchmark which seems to test archiving, multi-tasking, compressing, image editing, etc...)?
    CRC stands for cyclic redundancy check.
    What's the point of install/uninstall: the game files are packed and compressed into large archive files (*.cab in the case of AC).
    When the game is installed, the installer decompresses the game files from the archives, stores them to disk, and checks that the files extracted are corruption free by testing CRC codes (look for CRC on wikipedia).
    This operation is quite CPU intensive, and involves multiple access to your HDD especially when the files to be checked are large (those .forge files can be up to a few GBs I believe).
    So it is somehow a good stability test that stresses jointly CPU/RAM/HDD. I don't know what compression/CRC algorithm is used in AC, but this game more than others can trigger unstable OCs in my case.
    Why doing the install/uninstall from an iso: if you install from the DVD, the access time to the DVD becomes the bottleneck and the install process is much slower = not stressful enough for your system.

    If you want to setup a different test, you can try to compress whatever game folder (that preferrably contains both small and large files) using Winrar with best quality. Once the archive is created, you can open it and test it multiple times (winrar will check the integry of the compressed files using CRC).

    I tried the above experiment but for some reason it is not as stressful as the *.cab decompression with the installer of AC.
