Remove the side panel.....test
Point a small table fan at the innards...test.
Get a can of compressed air and a small brush.
Give the innards a good cleaning.
The brush is for the heat sinks and fans just in case there is some stubborn stuff.
Don't forget the psu give it a few shots of air from both directions.
That psu could be a quad rail depending on the model.
If it is it's suspect.
I need some help. My computer has been crashing for a while now when I am playing games. It usually happens when I am playing steam games but also when I am playing WoW but not as often. I have replaced my GPU with another one of the same model. I have checked to make sure I am not over heating and have run stress tests on my CPU and they are all fine. When I run a GPU stress Test using Unigine HeavenBenchmark 4.0 it crashes as well. I have checked all my drivers and they are up to date and have tried using older drivers in case was a problem with the new ones. The games I am playing are not even that heavy graphically. Even something like CS:GO crashes it but only when the game tries to load I can still get to the main menu on them with no problems. I am thinking it is either a problem with my PSU or my Motherboard. I would like to figure out what it is before I go and spend a few hundred dollars replacing either or both only to find out it is still happening. Any help would be appreciative. I am running a AMD system with a Gigabyte GA-F2A55M-DS2 AMD A55 with an AMD A10-6800k. An Asus R9 270X with 4gb GDDR5. My PSU is a Thermaltake Toughpower 750W
