Hello, This is my first post so please let me know if I am missing anything that will help diagnose this. I will try to be as detailed as possible.
I first noticed that something was up when I checked the resource monitor and the RAM usage would not raise above 22%. I have 16G (2x8G) which comes to about 3G of RAM being used. After this value the resource monitor shows Hard Faults begin to appear.
Since seeing this I have run MemoryTest83 with the 2x8G sticks and with 2x4G known good borrowed from a friend. the tests passed each time that I was running them with only 1 processor. when running these tests with option All processors (2 cores) enabled it takes errors.
I have run the Intel Processor Diagnostic Tool. Running this on the i5 that I have, the tests pass.
I have had the suggestion that it could be the mainboard. I am looking for any suggestions, and ways to verify it.
