Yesterday, my computer powered off playing Rise of Nations, a longtime favorite of mine, but being an older game, (2003), it isn't the most demanding game in the way of computer resources. When it turned back on, the BIOS did not restart, and the display showed "input not connected". The only difference i can see is that the GPU, my XFX Radeon 5850 is blowing out lots of air and being very loud. Is the fact that the BIOS doesn't start up mean that its the cpu or motherboard? Or is the GPU causing this problem.

Lastly, what's the standard procedure for checking for hardware problems? I've never had to deal with this before.
Thanks!

Yes, the fans still run. And the LED's go too, so it shouldn't be the power supply.
I have a backup GPU card to plug in, but i don't think that it should interfere with the BIOS should it?

So far I've tried 2 HDMI cables, and the monitor still works with my XBOX. Unless it's just the HDMI port that isnt working, but the GPU shouldn't be making more noise.
