Only 118 Windows Updates installed. Most systems have 160 or more. Please visit Windows Update and get
ALL available updates (it may take several trips to get them all).
No memory dumps, or signs of BSOD's in the WER section of MSINFO32, but lot's of Live Kernel Events. And lot's of Live Kernel Events and errors in the nNidia drivers in the System log of Event Viewer. FYI - a Live Kernel Event is Windows saying that it shut down unexpectedly, but doesn't know why. This is most often a hardware problem (such as overheating).
