Hi,

I have a computer running Windows XP with eVGA 6600GT (PCI Express) (AMD64 3000+). I just recently installed this flight simulator (RealFlight R/C Simulator) and when I was playing it, my graphics just got messed up. The display was completely garbled. At first I thought it was just a problem with the game, so when I set the settings to 1280x1024 @ 16bits, it worked just fine. The 32bit setting at the same resolution was messing up my display. Later, I tried opening other software that I knew was working properly (Google Earth and X-Plane), but now even they are messed up! But once I close the application, everything goes back to normal.

I tried installing newer drivers for my motherboard and graphics card - but that didn't do anything. I just formatted my computer and reinstalled Windows, expecting the problem to go away. But guess what - it's still there! I ran "dxdiag" to check for problems, but that's working fine. Any suggestions? I have a screenshot of what it looks like when running Google Earth (on my newly formatted + reinstalled Windows): Screen Shot. I would really appreciate your help in solving this problem. Thanks!

Hi,

I was just playing around with Celestia (a 3D app) in Linux. I'm getting a similar problem. I'm suspecting that it means that there is some sort of hardware problem. What do you guys think? :(

Thanks,
Jimmy

I just spoke to eVGA customer support. The guy made me check the voltages going to my motherboard. I'm getting 11.71V on my 12V rail. He said that might be the problem. Does that seem right? I'm using an ASUS A8N-SLI Deluxe motherboard with a OCZ Modstream 450W powersupply. I'm also only running the graphics card, a sound card, a HDD and a DVD drive on that.

I'm also going to check to try and plug in my graphics card into some other computer and see if it has the same problem there.

lol. Jimmy i agree with what your finding, you know more than the evga tech support guy. ;) and i never seen the lack of .3volts on the 12v do artifacts in games, bad video cards do that..once you check it you will know for sure. then just talk to evga's rma dept and say what you did to prove its the card

Voltages my ass. Make sure that the cables are all plugged in correctly (does your model of the 6600GT require an additional power plug?) and if it still does it, RMA for hardware failure.

You can't trust the voltages in the BIOS or windows much, the only sure way is to use a multimeter. I suspect if you were to connect one to that OCZ power supply, it would read within spec. Fight for the RMA, everyones seen the screenshot, it's typical for a bad card.
