Hi, For the longest part of a couple of months now, my computer blue screens almost everyday. I am pretty certain that it is because of either faulty RAM (memtest and Windows Memory Diagnostic tests always fail) or the NVIDIA GeForce MX4000 video card (onboard) on my system. I am attaching the "BugCheckCodes" of the last 12-13 crashes. Here are the codes: BugCheckCode 00000019 BugCheckCode 1000000a BugCheckCode 10000050 BugCheckCode 1000000a BugCheckCode 00000019 BugCheckCode 10000050 BugCheckCode 1000000a BugCheckCode 1000008e BugCheckCode 10000050 BugCheckCode 1000000a BugCheckCode 1000008e BugCheckCode 1000000a I would really appreciate if someone could help me understand what these bugcheck codes mean and more importantly, what device driver causes these crashes. I can provide more info in terms of the memory dump files, if the need arises. All and any help is really appreciated. Thanks.
