Well now we are down to trying to make it crash again and get a new BSOD report. If you can post the mini dumps you have that might help. If memtest ran fine with no errors, generally it means your cpu and ram are ok.
Here are some things you can try to force a crash, prime95 run for at least 30 minutes (prime95 is a test for cpu and ram but much more stressful than memtest86), furmark run for at least 30 minutes (tests video cards). If either one causes a crash by itself let me know, if not, try running both at the same time, this will put a load on the psu, sometimes psu's fail under load.
While running the stress tests, download and open HWmonitor, let it run the entire time you are stress testing. If it doesn't crash, take a screen shot of the HWmonitor window and upload that to dropbox or similar and post the link here. HWmonitor will show voltages and temperatures which may lead to an answer.
Another thing that could be the problem is the SSD or hard drive. The mini dumps or a new BSOD crash should show any hard drive related error. Generally they are 0x7(a-f) codes. The speccy report does not show any problem with either the Intel SSD or the hard drive, but SMART data is not a perfect error detection tool.
