Guys need help, i'm desperate !
The system worked perfectly until I replaced the graphics card and i think something has changed in my DSDT.aml because can not boot anymore and when I remove DSDT from Extra, the system boot. Secondary problem is QE/Ci. The new graphics card is nvidia GTX 275. With old graphic card nvidia GT220 system worked perfectly. Please help. I can not return to Windows. I'll kill myself.
Here is my old dsdt. What i need to change in DSDT? Please help me. Thanks.
