Video spike-like artifacts in 3-d graphics
Since installing this adapter in my PC, Google Earth exhibits what I would call 'spikes' sticking out of the earth image, and in all subsequent GE navigations. (Image attached)
So, I went to NVidia's control panel option "Adjust image settings with preview", and it also has these strange spikes sticking out of the rotating image.
No settings changes seem to fix this problem. I've installed the latest drivers for this card - no improvement.

It looks like a driver problem - sometimes, the latest drivers introduce a new problem while fixing an old one. I would suggest going farther back and using an older driver.
I agree
I've seen similar corruption on the background on spikes.bmp and it was a faulty video card. Have you got another PC you can try the card on? You could also try reseating the card, its sometimes pretty hard pressing the card completely home.

1. I've tried every driver I can find that will install (Dell's NVidia drivers, apparently tuned to individual Dell models, won't install - none match my PC hardware (Optiplex 745)). NVidia doesn't seem to have any driver archive. I've tried Versions 175.19 and 178.24.
3. The card is seated properly.
I've turned off "Enable Write Combining" (Control Panel/Display/Settings/Adv

I'm betting it's a faulty card, can you try it in another PC?

No help.
so it works OK in another PC. Are you using the same drivers in both PC's? How much ram does the other PC have vs the Dell?

I think it's a driver issue, but unless this card was tested with something like a live Linux CD, it's difficult to narrow down. It could also be a hardware problem, but without further testing it can't be determined. Therefore, I think this question has very little usefulness for future readers and should be deleted without a refund, as there was very little response to the comments of experts.
I covered bases in detail, requesting more info,
I think all relevant posts should get a part.
We don't know who was on the ball and who wasn't.
For all we know a motherboard driver could be causing the issue

I'm in agreement with Callandor.
Asker didn't do the physical part of troubleshooting so no useful information was created. Is all speculation here.
