HI Everyone, I saw the other threads on this, but they seem to be a bit different than my own issue as my PC isn't a laptop. It's a machine I put together a few years back. I installed Win 7 (64-bit) on it at the time and everything was fine for a long time. I upgraded to Win10 several month ago and after a time, I started getting the SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (igdkmd64.sys). I tried updating to the latest Intel drivers ( 220.127.116.11.4425) using Intel's Driver Update Utility 2.5, but the PC blue-screens during the install. It successfully does the audio driver, and bombs out when installing the HD Graphics 4000 driver. I tried that 3 times. I'm attaching my Diagnostic Dump. Many thanks in advance.
