Hi, so I've been having this problem for a bit of time now but it hasn't been all that frequent but nonetheless it is really annoying. So most of the time if not all of the time it happens in video games e.g Just Cause 2, Amnesia, Mass Effect 2, and pretty much all the games on my Steam library so like 35-40 games.
What happens is the screen freezes and the mouse doesn't move ctrl alt del doesn't work and it is just frozen on where I was in the game when it happened. Sometimes it can have a little freeze where it comes back shortly after but that is very rare over the other freezes. Whenever it freezes I press the backlight button on my Logitech G19 and if the lights go off on it then it's either the game had an error or it is just a 5 second freeze, but if when I press it the lights stay on but the LCD screen on the keyboard goes black then I know that I have to press the restart button on my tower.
I have waited plenty of time and tried ctrl alt del to see if that works but to no avail only restarting the computer works. I keep my computer fairly clean and it doesn't get hot and I only did a clean install a couple weeks ago.
Any help and ideas to see if I can fix this problem would be appreciated.
