I have just reformatted Ubuntu, and have updated the drivers.
Games from Steam crash and the computer shuts down immediately upon loading or starting the game. This happens both on Windows 7 and Ubuntu.
I have 6GB RAM
GT 630M graphics card
Core i5 -2450m 2.5GHz CPU (Acer V3 771G 6601)
Games like L4D2 and TF2 shut down the computer instantly. Is it a hardware malfunction? According to the specs it can handle those games easily. Help please!
