Looks like you ruled out the graphics card and keyboard.
Did the crashes seem better or worse to any degree?
Last 7 crashes on the 25th:

Run a full AV scan.
Driver Verifier didn't show anything previously, so that won't help.
Let's try a Clean Boot.
Clean Boot by unchecking everything in msconfig>Startup except AV: Startup Programs - Change. After reboot enter msconfig>Services, check the box to Hide All MS Services, repeat above.
Are there any yellow triangles in Device Manager?
Check all the PSU connections, remove the cable, inspect cable end and socket, firmly replace the cable.
Try to re-create the crash scenario.
CPUs are normally not the cause, but they do occasionally fail, since you have one to test with swap them out and test.
