So I just got a new graphics card for starcraft, AMD Radeon HD 6870. But whenever I boot up a game, the computer crashes. I've switched back to my old GeForce 8600 GTS and everything works fine. Any ideas?
I'm using a ThermalTake 850w Blackwidow power supply and running Windows 7. 4 gigs ram. I've downloaded GPU-Z and my GPU temps over round 38-40 C while idle. Not able to ever boot up a game so not sure how hot it will get while under load. |

Ok, temperatures in idle dont tell much to be honest. Stress your GPU (not with games, there are enough benchmarks aout there) and see if the crashes also appear.
But I doubt you have a temp. problem, I rather think you got some messed up drivers. Did you upgrade from a 8600GT to a 6870? If yes, use driver sweep and clean your PC of your current drivers and old nvidia drivers and then reinstall everything.
Also check if your GPU is correctly seated etc. |

| Yo. Uninstall the Nvidia driver before u plug the 6870 in, then install the newest AMD driver (12.3 Catalyst). Nvidia drivers conflict with ATI. |

| Yes, I upgraded from the 8600 to the the 6870. I'll try that Driver Sweep and see if that helps. |

| k, So I removed all traces of NVIDIA drivers and then re-installed catalyst and updated to drivers for AMD. Computer is still doing the same thing as before. I tried to rate my computer through Windows Experience Index and my computer crashes again almost immediately. Same goes for starcraft. Any help? |

| Sounds a lot like an unstable overclock IMO. |

Could easily be that the shit PSU is going horrendously out of spec every time the GPU tries to draw power off the 12v rail, causing crashing.
Unless I'm remembering wrong and it's not a piece of utter shit. |

What exactly does "crashes" mean here? Should help you determine whether it's a PSU or GPU fault.

| By crash I mean the entire computer shuts off. No warning or error signs when I boot back up. It's like I just shut the computer down. How can I tell if it is a PSU or GPU problem? |

That kinda backs my theory. IIRC, with 8600 GTS to a 6870, you went from a card that only drew it's power from the motherboard slot to a card that takes 6 pin PCIE power from the PSU, yes? And the old card didn't cause the crashes, the new one does? Specifically at the times the card would start drawing full power, like when leaving 2d mode?
That's PSU, most likely. |

Yep 6870 require 2x6-pin connector
I highly recommend PSU 550w+ for single card, 700 for crossfire |

No. An Antec 380D can hold whatever single card setup has to throw at it in style. You are indoctrinated (Mass Effect on the brain lol) by the marketeers that say you need 700W of power in your surging man-box to be worthy. |

Especially since the OP clearly stated he has an 850w PSU. All those extra "what?"s don't matter nearly as much as quality. |
