There are times when I am playing a game, (and thats the only time it does this, however, Minecraft works perfectly fine) then my PC will just randomly freeze. I still hear sound and my PC stays on. It seems as if the interface locks up; I can't move my mouse cursor, my keyboard locks up, (I know this because when I try to press NUMLock nothing happens) CTRL+ALT+DELETE doesn't work, and the only thing thats left to do when my PC does that is press and hold the power button to force shut it down. I have been trying to figure this out for months. Somebody please try to help me, I'm getting very frustrated by the things that I've tried and have failed.

Things I've tried: Dusting my PC, Changing keyboard and mouse, re-installing windows as an update, moved cables around inside my case, shutting it down as much as I can when I'm not using my system all to no avail.

PC Specs:
CPU: AMD FX-6100
GPU: GTX 650ti SSC
Motherboard: msi 760GM P23(FX)
Power Supply: Kingwin 650 watt
OS: Windows 7 Home Premium 64-bit

Keyboard: Logitech G710+ (tried swapping with a CM Storm Quickfire TK Cherry MX Red)
Mouse Logitech G402 Hyperion Fury (tried swapping with a Razer Abyssus)

Please help if you can, the worst thing about the problem is that I don't know what it is!

What do you mean when you say the motherboard is "marginal?"
