Great question. I have had nothing but trouble from first receiving this computer. HPE-150t from HP. I built a good project fifteen years ago and updated it many times, and, I was very happy with it. I bought the HP because it contained all the same components I knew and trusted; Intel, MSI, SoundBlaster, nVidia, etc. However, no matter what I or HP attempts, it is blue/black/reboot, and I am at a loss to troubleshoot it any longer. It not BIOS or software, as I have formatted and installed Windows 7 Ultimate from scratch. The only variable left is the MOBO, I think, therefore my original inquiry.
