GTX 660 OC causing system crash on web pages

[HacktheMac1013]

I have a Gigabyte GTX 660 that I put in my hackintosh. When I go to webpages that require adobe flash the whole computer will freeze with the spinning pinwheel. This doesn't happen all the time and it doesn't happen on only one site. Anyone else ever had this issue or heard of it. Thanks

I have a similar issue with an EVGA GT640 (Mountain Lion on a GA-H55N-USB3).

Unfortunately, I don't have a solution for it but it's driving me crazy.

YouTube hangs] the computer as well but I switch to using the HTML5 option to get around that. But still...

Try to right click the mouse on a video
(like utube video) and go to "settings" there go to monitor and disable "Enable Hardware accelerator" Worked for me.

Are you using chrome?

or flip4mac?

Both of these have given me problems with some video sites freezing everything. I recommend deleting both, especially chrome.

i have to test more but something change.

1) install last nvidia drivers here : http://www.nvidia.com/object/macosx-313.01.01f03-driver.html

2) put <string>darkwake=0 nvda_drv=1</string> in your org.chameleon.Boot.plist
after that also no able to set nvidia web driver but in cuda the drive change to last one (313.01.01f03)
i hope now no more crash and freeze
