HP Pavilion p6740f Desktop PC upgraded with Windows 8 (64-bit) with Media centre
Two weeks ago I changed my video card for an MSI GeForce GTX650 Ti Boost with Twin Frozr gaming; all worked fine until I was playing a game and the computer shutdown by itself as if there had been a power failure.
I had to disconnect the computer and tried to reconnect it a few times until the green power light in the back reappeared.
What could cause this issue? I happened 4 times so far.
