I had a Hackintosh running flawlessly on following setup:
ASUS P7H55-M LX
Socket: LGA 1156
Chipset: Intel H55
LAN: Realtek 8112L Gigabit
Audio: VIA VT1708S
Intel Core i7 860 2.80GHz
NVIDIA GeForce GTS 250 1GB
A few hard drives
Seagate ST2000DL003-9VT166 2,0 TB
Seagate ST31000528AS 1,0 TB
Seagate ST3500413AS 500 GB
Western Digital WDC WD20EZRX 2,0 TB
OCZ Vertex 2 60 GB
Niresh's 10.9 Mavericks
Everything was running perfectly, until my graphics card broke. So, i bought a newer one:
SAPPHIRE HD 7950 3GB OC GDDR5
Since then, my system wont boot.
I tried to reinstall, but something occurs after the first phase of installation (after the first reboot)
> If i try to run the system without any boot flags, after a few seconds after bootloader screen i lose video signal, and my monitor shows: "No video connection"
> If i use -v , i got stuck on this line before video turn off:
> if i use -x, -f, npci=0x2000, pciuid=0, or any combination of this boot flags, i got stuck on this same screen, but without video going off.
> if i use GraphicsEnabler=No, the system boots, Audio and lan works, but resolution stays on 1024x768, and system info shows ynder Graphics : "video 3MB"
Yosemite installation got stuck on ths same line, even before first setup appears. (Even with GraphicsEnabler=No)
Any idea of what i'm doing wrong or what can i do to solve this ?
