Alright, my GTX 760 has been experiencing a huge idle temperature recently. I haven't really checked the temperature of it before the event I will describe below, but after it I noticed my temperature was 80 degrees when idle.

So, I was playing a game of League of Legends when suddenly my computer made a large sound (presumably the fan speeding up) and both of my monitors shut off. Immediately afterwards I went to ask my brother, seeing as I am not very familiar with the ways computers work. He recommended cleaning out my case, and seeing as I was lazy and didn't have a compressed air can with me, I ordered one online and waited to clean out the dust in my case. I decided to clean the case out, and pretty much every fan was extremely covered in dust, to the point where it looked like a solid wall on the other side of the fan. I figured this would fix my problem once it was removed, but it didn't. The idle temperature remained at a constant 80 degrees, and the only reason it doesn't crash my computer during gaming is because I am running EVGA Precision X to keep the temperature at 80 C.

My question in particular was, should I re-apply my thermal paste on the GPU? This card is at-least a year or two old, and the dust around my graphics card was successfully removed. I have little experience in applying thermal paste, but watched a few tutorials on it on youtube which were practically the same and made it out to be easy. So, would my problem likely be with the thermal paste, or something else?

I'd also suggest some tips on replacing thermal paste if you have any, as I am not too familiar with computers seeing as my brother practically did all of my computer problems. He recently moved out, so I cannot have him come over to help me himself at the moment.

Thanks in advance.

Replacing the thermal past may very well help but I suspect you haven't cleaned out the card fully, dust and fibre gets blown into the small heatsink fins below the fans and is hard to see.
I suggest you remove the card and go outside then use the air can to blow backwards through the heatsink, that is to say blow from the edge and underside of the cooler assembly towards the fans.
