  1. It sounds more like a power problem. Make sure everything is plugged in properly because if your pc aint recieving power it aint going to work for long
  2. How many components in your chassis? Is the wiring a mess? Is there adequate airflow so that you can feel the heat being forced out of the unit. Touch your GPU and see if it leaves a blister. If you want to figure this, you can get spec sheets and check current draw for max settings. Going further, you could use an AMPMETER inside your box at the supply input. It takes balls, but can be done pretty easily.
