Don't scrimp on the power supply. And check ALL your fans.

Make sure you have enough wattage. It hurts nothing to have overkill in this area, since a supply will only use the power drawn from it and not waste it, so I would not go for anything smaller than 400W, and bigger is better. I fully expect to have a 1 KW supply in my next system.

Good quality is important too. This has been a good source for me.

It should be easy enough to test fans, even ones that are hard to get to. Checking for airflow is obvious. A thin folded piece of paper shoved into the fan area (listen for the rattle) is good for those out-of-the-way fans on circuit boards or processors. I fried my last graphics card when its fan quit. Some processers will melt down in less than a minute without a fan, although more recent ones, and older Intels, have temp sensors that shut them down if they get too hot.

This is probably not your problem, since you say the computer eventually ran normally. A bad processor cooling system with a computer designed to detect it will start, and then shut down quickly.
