100% Certain My GPU Is Causing My System To Crash, But Why?

So my friend gave me his GTX 770 that he's owned for one year. As soon as I installed the card into my system I realized that my computer would crash while gaming about once or twice a day, but it doesn't always happen daily. I'm 100% certain it's the GPU as the problem subsided once I switched cards out.
The highest temps I've seen the card go to is 80C after a couple of minutes of gaming. I've never dusted the card out or changed the thermal paste so maybe that's the issue? Also the card is under-performing at a GTX 760 level.
Does anyone know what the problem is?
 
Solution
Is your power supply up to the task? I would AT LEAST blow out the heatsink and fan with air. I would not suggest to you that you remove anything off the card yet. That would be for after you have the problem solved.
