Hi,

I recently built myself a new computer and gave my son my old desktop for school use. Since giving it to him it has developed this odd issue where the computer will boot and load windows and then the display will turn off. If I power cycle the monitor, the display will show for less than a second before disappearing again. I did a complete reinstall of Windows (formatted the drive and a fresh install) and the problem went a way for a little bit but now it has returned. This problem also persists when trying different monitors. My though was that it has something to do with the old graphics card I put back in to the machine, but don't have a spare to test. Any suggestions?
OS: Windows 10 Pro
Graphics card: Nvidia 660

Any help will be apprecited.

I didn't find the right solution from the Internet.
