Question Computer crashes becoming more frequent

[carbonshock]

I have been having occasional crashes on my computer over the past year and they have become more frequent in the past week or so, 5 so far today 3 of which were in the last 25 minutes

The crashes always start with the screen going black with audio still being played (music) then a few moments later the computer will reboot.

As far as I can think of it has been whilst playing a game but I couldn't say for certain that it hasn't happened when not playing a game.
