Power Supply Fried the Motherboard. Bought higher speed mother board and newest Intel Chipset last year. Ran it with original Win 8 Hard Drive - It installed itself - bang - NO ISSUES. Switched hard drives with my Windows 10 computer (due to Memory)and like wise it - There were no issues. The Win 8 HD in my formerly Win 10 Computer had a few drive issues on the sound and audio drivers - put nothing major. It runs better as it is not the memory hog of Win 10.
