So hey guys,
this problem started appearing about 5 days ago, and it goes a little like this:
- Playing a game, such as Battlefield 4, or war thunder.
- i play flawlessly for about half an hour, (flawlessly in the way of graphics problems)
- The game unexpectedly freezes, along with my whole computer. The audio playing stops and plays a recurring buzzing loop sound,
- I can't control alt delete, the keyboard is unresponsive, or not recognized, the mouse wont move, all i can do is just keep the restart button pressed on my computer until it restarts.
It boots up with no problem after that, but has created no dump files or anything like that. I mean it doesn't even have the common courtesy of blue screening me, it just freezes and plays that annoying audio loop. So im in quite the pickle. Otherwise, if im not playing a game, just watching a video on you tube for instance, there are absolutely no problems with my pc.
What I've done:
- Changed my PSU today, put a 650 W instead of my old 500W one,
- Completely re installed windows. (64 bit windows 7 professional)
- Put in fresh 8GB of RAM,
So what could the problem be? im confused and not happy at all!
Computer specs:
Sapphire Radeon HD6770 1GB
Intel i5 750 @ 2.67GHz 2.79 GHz
MOBO: Gigabyte P55-US3L
PSU: 650W
Ram: 2X4GB Corsair vengeance

I also forgot to mention that my temperatures are about 40 - 50 degrees on average across the board (CPU, VGA)
 
Solution
Since you re-installed Windows and the PSU, the issue could be with the video card, maybe the RAM. CPU is very unlikely.

You'll have to test the card in another system that can handle it, or test a new card in yours.

I think your CPU is severely outdated, for a game like bf4 you need at least 3 ghz CPU. You could try buying an after market cooler and overclocking it to at least 3 ghz although I don't recommend that. Best option would be to get a new CPU at this point, your CPU is bottleneck everything else. Refer to the BF4 minimum specs also for some reference.

Try playing the game with the lowest texture settings. Just the textures. This will show you if it's your GPU's memory problem. If it lags again then try to do some GPU and CPU benchmarks and use Prime 95 for about half an hour to see if it's a CPU or GPU issue.
