Windows 7 - GTX260 Video Artifacting/BSODs

If you have a best buy near you, grab this PSU and test your system with it,
Antec - EarthWatts 650-Watt ATX CPU Power Supply - EA 650

I know for a fact that this PSU will run your machine since I ran one for 20 days while I rma'd my Antec Trio 650, and my machine is loaded with parts, 8 hard drives, DVD-RW, SB Card, GTX 285, 4 case fans, 4x2GB sticks of ram.

I hate to see you just buying parts to try. That is an expensive form of diagnostics. Keep in mind that servicing a computer while not being on site is difficult, if not ridiculous. I am not at all sure that you need a motherboard, or a power supply, or a video card. It would be nice if you could eliminate one or more of these as a cause.

Are you still running with that Rosewill power supply? I thought you said a while back that you replaced it, but I don't remember.

But let's look at some facts: If you run the game at it's lowest settings and turn off all of Window's 3D eye candy the problem goes away? That is a clue. That means that your system can handle standard graphics, but anytime you ask for some horsepower it can't do it.

Try some tests:
Assuming the card is back in the x16 PCIe slot and you have clean installed the latest WHQL drivers: try this:

Go to Programs > Games and open Chess Masters. Does the video crash opening a Windows 3D game? Try it with a non-Aero desktop and with.

Run the Windows Experience rating. This tests the video card through all the gaming stuff. Does it crash or show the TDR?

Unplug all the equipment you don't immediately need: DVD drive, all USB devices, case lights. Disable the LAN and Sound devices. Basically power down everything you don't need to run the computer and then try to recreate a crash.

Try and think of anything else you could do to test the system to try and isolate the cause.
HTH

If you still have the Best Buy receipt it should tell you their return policy in the back of it. Fabe

Rosewill is not known for high quality parts. They are a re-brander. They are known for decent quality at a low price. The power supply is one part that I would not skimp on. It has to work perfectly. I would replace that before anything else.
The consensus in the builders forums for high quality power supplies is Seasonic, Corsair, and Thermaltake. Antec can sell a good supply, but they don't make em either. For a while they had Seasonic making their supplies, now they use others.
For your rig I would only start at 650W. If you can get a larger one on sale for the same money, I'd do it.

What ya think of that one? I had been lookin at the 750Watt corsair but that 650 looks pretty good
