If it isn't hardware, it's software. Did you install the motherboard chipset drivers from the makers site after installing Windows 10?
If it doesn't work on a clean install of Windows 10, try an upgrade install from Windows 7.
I installed windows 10, the problem I am facing is that everytime after 1-2 minutes. Systems blinks and keyboard and mouse stops working. I had to hard reset. First I thought its a hard drive problem, but when I installed windows 7 it worked perfectly. Again I moved back to windows 10 and have the same problem.
Any suggestions what should I do? Clearly its not a hardware problem
