I have this power supply coolmaster
1469-FUENTE 750W PSP PFC ACTIVO COOLERMASTER

Recently I was having odd problems with GTX 570 (of driver failed) since I did the last update of nvidia, this lead me to buy a GTX 770, but for some reasons this card doesn't even start on my machine because after 5 sec logged in windows 7, it just crash by shutting down the machine.

It lead me to think that it might be a power supply issue, and I was wondering if there are ways to test this possibility (I don't have other computers to try or other power supply)

The computer is about 3 years old...
