I've just experienced something that I have never experienced in the past, today.

I have a Toshiba Satellite A-100 laptop. It has some heat dispersion problems so the machine tends to get pretty hot sometimes when I run apps that require a lot of CPU and GPU power. I was running a game (Counter-Strike: Source) today and my laptop display suddenly cut off completely (identical to when the laptop is powered off). I still got audio but there was no video at all. I force shutdown the machine and restarted it. The machine started, but the display was still blank. Suspecting either hardware failure or overheating, I left it off for 30 minute and tried again. This time the display came back on.

The graphics card I have is a nVidia GeForce Go 7600 and it seems most of the heat is coming from the card. I'm wondering if GPU overheating can cause the situation I described above, or is it something entirely different that causes a issue like this.

Most definitely. If it has a removable card, pull the card and clean the fan, if it has one, and the heatsink
I'd get a can of compressed air and blow out the fan ducts for the CPU also
