Primary display issues

[jvxr]

Have a weird issue with my hackintosh; sometimes on resuming from sleep, the primary display goes into a mode that shows a screen with those fuzzy white dots, like a tv channel that has no signal. Some other times, the display switches on and off. When I tried to take a screenshot of the issue the screenshot actually came up with the contents, even though the display wasn't showing it.

Here is the config
Core i7 3770K

16 GB DDR3 Ram Kingston HyperX blue.

128 GB SanDisk Ultra plus for OS install

2 TB Western digital Green drive for storage

So after months of living with this issue, I think I found the solution.

Did a clean install of 10.8
Rebooted from USB drive, chose my SSD partition to boot from.

Did a disk verify and repair

Renamed /System/Library/Extension/AppleTyMceDriver.kext AppleTyMceDriver.kext.orig

Repaired disk again.

Ran Multibeast 5.4.3 , Set system profile to MacPro5,1

Repaired disk again, rebooted from SSD.(OSX install)

Downloaded & applied the 10.8.3 update

Downloaded and installed the Nvidia web drivers from http://www.nvidia.com/object/macosx-313.01.01f03-driver.html

Edited the /Extra/org.chameleon.Boot.plist file's Kernel Flags to add nvda_drv=1

<key>Kernel Flags</key>
<string>darkwake=0 nvda_drv=1</string>

Repaired disk again, Rebooted.

Eventhough the nvidia utility says that the driver isn't loaded the actual logs say that the web driver is in use.
Open the console and search for NVDA
It should show something like this.

I have been running this setup for a week and it seems stable for now.
