I recently bought the 1GB GDDR5 Radeon HD 5830, installed it, and it worked like a charm. I played WoW and kotor on max settings the last few days. It was working perfectly and I was really happy with it. Today, while I'm playing WoW, my computer locks up all of a sudden and I have to reboot. When I do I get no display from my graphics card. However, I do get display from my onboard graphics. I decided to let my computer chill for a while and came back a couple hours later. The same thing happens. The onboard graphics works, but the card doesn't. I then try taking my graphics card out and reconnecting, but it was no use. When my computer runs, the graphics card runs too so I'm not sure what's happening. I need some help.

Sounds like the video card was overheating, maybe you should look at some alternative cooling system or add an extra fan... It is possible that the card as overheated that much it has failed already!? try that card in another machine just to be sure... Is the CPU fan free from fluff/dust etc...? maybe take a good look at that too. Also isn't most gamers using a more powerful PSU of something is the region between 500W & 900W.... don't know myself as I am not a gamer... so just speculating ;-)
I think it overheated too. Boot the computer up and get into BIOS. Go to Advanced, and select Chipset. In Chipset, you should see "Primary Graphics Adapter" (might be under Advanced > Southbridge configuration). Anyhow select "PCI Express" as the default. Now, go to Boot and select Hardware Monitor. What are you Motherboard and CPU temps like? Don't forget to save and exit. I hope it solves the issue.
