  • MemTest86 Tests 6 and 8 Errors Report - Memory Failure?

    The last few days I had some strange behavior on windows 10. Games wouldn't play and crashed to BSOD (not all games). Reinstalled games and still crashed. Then my water pump failed in my kraken water cooler. Replaced the cooler and games still crash. Reinstalled w10 and games still crash.

    Just ran memtest86 and it encountered 2 errors. Thinking about buying some new ram to replace the potentially bad ram. Not sure if there is a problem with my CPU? Please see report below:
