Windows 7 Laptop persistent freezing/lockups randomly

Ok, so I've finally decided to make my own thread about this rather than keep looking for solutions in other people's threads. My laptop has been freezing up very randomly since Christmas break, and I've run just about the gamut of ways to fix it. It do not believe it is an application problem because its happening in safe mode even.

What happens is I can be doing nearly anything and the screen will flicker a little bit, a little flashing, and as soon as this starts, everything is frozen, even caps lock is unresponsive. It can happen while surfing the web, while playing games, during start up, just after start up, you name it.

I think we can eliminate it being the video card because with the driver uninstall, the problem still happens.

It also doesn't seem to be a problem with CPU because the usage seems to be low when this happens. EDIT: It's definitely not the CPU: I was just observing it while it happened and it was at a measly 4% usage while I was just sitting doing nothing.

Event viewer is of little help, I tried to uninstall several applications that had been running concurrently with the shut downs, to no avail.

I'll attach my dxdiag

The computer is an ASUS brand G60vx series notebook. I'm running Windows 7 Home Premium 64-bit. Sorry if this isn't enough info, let me know what else you might need. I'd appreciate all help on this matter.

I think it will also help to mention that this computer is nearing its 2nd birthday, and I'm highly suspect of the age being a factor.

I forgot to mention, also what happens is that the sound playing will become warped and degenerate into a buzzing crackling type noise (can't really describe it beyond that). This leads me to believe its the sound card, but I only have one thing showing up in my device manager the High Definition Audio Device.
