Actually... My New Bios is in Legacy boot right? what happens when i go to my bios setting and change boot mode setting... Like UEFI -> Legacy BIos

Yeah That's right.. But when i always go for Legasy boot It froze for 1-2min and says that "display driver graphics stopped responding and has recovered" It does that everytime when I'm launching programs

Ok So i have problem with my G75vx gaming laptop.. So I try to boot with dos usb with step below "To be able to boot into your USB Stick, you must go to your BOOT Tab and DISABLE Fast Boot, Enable Launch CSM, DIsable PXE Rom, then go to your SECURITY Tab and DISABLE Secure Boot_ Save changes in BIOS and restart, press ESC and it should bring up the boot menu with your USB Stick as a selection, select it and you got it" So I backup my original bios which is..80.04.60.00.0e and I unlocked it and New Mod bios was 80.04.60.00.10. This is where problem starts... 1.So when I reset my bios setting to normal and reboot, it shows me that my bios is not unlocked (GPU-Z shows me that BIOS version is 80.04.60.00.0e which is original bios version) 2.When i boot with " BOOT Tab and DISABLE Fast Boot, Enable Launch CSM, DIsable PXE Rom, then go to your SECURITY Tab and DISABLE Secure Boot" this bios setting i can see that i have unlocked my bios which is bios version 80.04.60.00.10 but display graphic driver kept stop working so i can't barely launch programs...(It froze like 1min and says that "display driver graphics stopped responding and has recovered") I don't know how can i solve this problem....can somebody help me? please ? *more information* *I'm using windows 8.1k *so basically i have 2 bios in my G75vx...
