So I've installed the Splinter Cell: Blacklist game and, then when the game loaded to play, my PC shutted down and I couldn't turn on the PC afterwards.

This was happening too with the game Mafia 2. I don't know if this is an GPU issue or a CPU because my proccessor turns to 85ºC sometimes when I'm playing, and my fan is working perfectly...
Sorry my english.

My system:

Windows 7 - 64 bits
Intel Core Quad 2.50Ghz
Radeon HD 7870 GHz Edition
4 GB of RAM
