Windows 8 and GTX 680M issue. Cannot install. Please help

[evidence87]

Hi guys,

i have just purchased Windows 8 Pro and installed it on my Dell M6600. But there is a problem. I cant install the drivers for my GTX 680M. However, i was using lv2go Windows 8 drivers while running Windows7, because theres an issue with upgrading my laptop with a GTX 680M. And they work perfectly untill now.

When i tried in a common way - it just says that installation failed.

When i disable Driver sign enforcement - it however asks me if i really want to install that drivers but then still crashes after 10-15 second of installing and blinking. Sorry, not crashin - failing. But then strange thing happens - i cannot launch the installation again - it cannot verify my card and says that i have no nvidia compatible device. Damn, i think i am cursed...

Please help me...

Hi Guys,

just installed dox's 306.02 drivers but there's a small issue. I have gtx 680m with 4gb of vram but dxdiag says that i have approx. 8gb of vram (though my ram is 8gb). Is that okay?

But i cannot install any other driver but dox's 306.02. I've encountered an error with some chipset pci express port 0101. Did anyone has such an error?

Had the same problem as you. You have to disable the force driver signing and then do a clean install.
