NVidia 6600 GT display problem
I notice when using google earth, the display winds up very broken up. I thought it was the app, then tried some game and the same thing happens. I wonder what could be wrong. Perhaps it's the driver?

Heat? Does this only occur with 3D? You may want to verify if the fan on the card is still working.
Experience is something you don't get until just after you need it.

Yeah, only when 3d apps are running. I checked the card, and te fan seems to be running alright. I took it out, reseated the thing, checked for debris in the fan (lots of dust) and restarted.

Hi Donkey Punch,
SirDice is correct in that heat is the most common cause of this sort of thing.
This can sometimes be be provoked by people being too aggressive in overclocking their cards.
As you seem to have suffered from a heat problem, the only other thing I would suggest is removing the heatsink, cleaning it and the CPU and replacing the thermal paste (or patch) with a silver based compound such as Arctic Silver or Antec.
I have never removed the heatsink from a 6600GT, but I strongly suspect that it will have the standard "white gunk" or a patch, and the silver compounds are 20x more efficient than either of those.

A lot of the time the memory gets too hot and becomes damanged. If this is the case it is irrversable so good luck to ya -- hope it isnt.

No, I never overclocked the thing. I think it is a heat problem from too much dust and other crap.

I suspect that you may have gotten away with it. These cards are fairly robust, and you don't mention seeing any "magic smoke?"
I would still be inclined to replace the thermal compound though, in case it has been compromised or started to "leak".
I am guessing that when things started to look weird you gave up fairly quickly, so you could well have avoided any permanent damage.
Basically just give it a quick test and see if it works, now you have evicted the dust bunnies.

I have no idea what tests to run. Therefore, I have no idea where to start.

Easiest is to look at Google Earth and the Game again. Then replace the thermal paste.
What operating system is it?............... I will post you a link to a free "video card stability test"
I am a bit old fashioned, as I like to test with real applications before using benchmarking and analysis tools. My reasoning is that if it doesn't work with a real application it almost certainly won't with the more rigorous testing software, and even if it did, that isn't much good because it is the apps you want to run?
OK if the tests did work, I would at least try updating the firmware, and patching the applications.............
