Computer running hot and powering off

So I've had my PC for a good year and a half now, and recently, it's started to run incredibly hot with certain games, to the point the computer shuts itself down. The only games it has issues with is Bioshock Infinite, where my PC will shut down withing 10-15 mins, and FarCry 3, where my PC will shut down after an hour or so. It's started to run hotter in general, but in these games the mobo touches the mid 90's, as does the CPU. The GPU stays at roughly 85 in both of these games. On a whole, other games such as CoH run cooler but still hotter than they used to, with temps reach the 70's & 80's for the CPU/Mobo.

Generally been maxing all the games aswell, as I don't play in 1080p (got a crap monitor), I play at 1280x1024 (don't know what that is in P terms haha)

Specs are as follows: 

Mobo: ASUS M5A78L-M LX V2
CPU: AMD FX 4100 
GPU: Saphire AMD Radeon HD 6870 
RAM: 8GB G Skill Ripjaws
HDD: 500GB Seagate

None of the parts are overclocked either, literally all running at stock levels.

If you need more detailed info let me know, and thank you in advance for any help :) 

I haven't cleaned it but it's not particularly dusty inside tbh. There's a bit of dust, but not huge amounts, not the sort of amounts that would cause a 10-20 degree rise. I'll give it a clean anyway just to be sure, what's the best way? Individually wiping componants or bustin' a hoover?

CPU Cooler fan is still working, all fans are still working. I read somewhere that it could be that I need to reapply thermal paste?

What kind of case is it? And what is the ambient temp that surrounds your computer? Those are biggies when it comes to temps.

Cheers for all the replies guys, ordered a can of compressed air to clean it, and a couple of fans to stick on the back to improve the airflow. If the problem persists, I will reapply thermal paste. If it persists after that, my fist will go through my computer.

Thanks again :)

1080p is a TV standard, not a resolution. There is no TV standard that corresponds to the resolution 1280x1024.

Your computer shuts off because your CPU is getting too hot, I guess. Some cases have air filters where the air comes in. Clean them. Get all the dust off your CPU cooler. I use a new painbrush (gently) and a vacuum cleaner hose. If it's still too hot, take the cooler off, clean the grease off both the CPU and the heatsink with a dry paper towel and some Q-tips, and apply fresh grease before remounting the cooler. All heatsink compunds work OK. Unless you're doing something like a massive overclock, the brand won't matter. Don't apply so much it smooshes out into the pins of the CPU, because some of them have aluminum in them.

Ah sweet, always though they'd be in the region of £35-£40 for a good one. Cheers man, will definitely pick one up, been wanting to OC for ages haha!
