PC freeze then black screen on startup

[lawsoneve]

This has only happened twice but has scared me half to death both times. I will be playing a game and my audio will slowly fade and then my PC freezes. I will be able to hear in game chat but i cant hear anything else. I cant ALT-Tab and i cant ALT-F4 so i am forced to hard restart my PC. Upon startup i am presented with a black screen and a small white line similar to a type log. I then have to restart my pc 1-2 times and then it will boot up saying it is installing/completing a windows update. Is my PC just auto updating while im playing or is there something bigger going on? I purchased a prebuilt PC on a tight budget so i am not looking to replace parts if i dont have to. Thanks in advance

Not sure how you missed answering the above and being that the PSU is a prime suspect as the cause of this we need to the information before go any further, will look at Speccy but hold off with any feedback until we have the PSU details.[/color]
