Asus GTS 250 1gb. Screen freeze with strange squares and stripes and start blinking.

[Squatch]

Hey, everyone!

 

I have successfully installed mac os, with [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url]+[url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] method.

 

But I have one last problem. My screen freezes with strange squares and stripes on it and starts blinking. But system keep working, sound keep playing, mouse cursor still alive. And I still have access to the system by ssh.

 

It happens randomly. Sometimes after 2-3 hours, and sometimes after several minutes.

Often, when watching flash video in browser. But not always.

I suppose it's video related problem. But i don't know how to solve it. QE/CI works fine.

No matter how I connect monitor - over VGA or DVI.

 

My system is:

mb: ga-h55m-ud2h rev 1.3 (bios f11)

proc: core i3 550

video: asus gf gts 250 1gb (ENGTS250 DK/DI/1GD3)

ram: 2x2gb Kingston 1333

pm: Thermaltake TR2 RX 550W

 

Installation method:

[url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] + Mac OS 10.6.3 Retail + 10.6.5 Combo update + [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url]

 

[url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] options:

UserDSDT Install

System Utilities

Audio kext: ALC8xxHDA + AppleHDA Rollback

Disk kext: IOAHCIBlockStorageInjector

Graphics kext: NVEnabler

+ Lnx2Mac Realtek RTL81xx driver for Network

 

I also tried to install "32-bit Apple Boot Screen" option with [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] if it matters.

My guess was "GraphicsEnabler=Yes" could help, but it's not.

 

p.s. Sorry for possible mistakes. English not my native language.

 

Any ideas or advice will be appreciated.
