Yosemite freezes too often

[evildog1]

Hi

I succesfully installed Yosemite my 1 TB HDD but there is a problem. Yosemite freezes too often. it happens in installer too.

In BIOS, i set my BIOS as Optimized defaults and i changed the following settings

- Disabled CPU Turbo overclock (overclocking the CPU makes a lot of problems)
- Change boot #1 to USB Flash Driver (as a primary boot)
- Change boot #2 to my second HDD that Yosemite must be installed
- Disabled all other boot to avoid confustion
- Disabled Intel Graphics because i have Nvidia GeForce GTX 760 video card

The following settings are set as default
- Other OS
- Disabled Secure Boot Mode

My computer does not have GFC-lock and my CPU Intel Core i7 4770k does not have VT-d


First try. i boot into installer without any flags but it freezes when i click partition. i have to hold power button to turn off my computer and turn it on again (reset button does not work)

Second try. i boot into installer again, created 120 GB partition for Yosemite and 800 GB partition for other stuff and start installation but it freezes at 12 minutes. i have to hold power button to turn off my computer and turn it on again

Third try. i used the flag "-x" and boot into installer again. formatted 120 GB partition for Yosemite and start installation but it get's stuck at 14 minutes. i click on Apple logo and click restart.

Fourth try. i used the flag "-x PCIRootUID=1" and boot into installer again. formatted 120 GB partition for Yosemite, start installation and it succesful.

i rebooted my computer and choose "Yosemite" without any flags. i setup and configrate my Yosemite and everything done. The graphics, keyboard, mouse and other thing works fine expect audio. When i used it for 3 minutes, my computer freezes and i have to hold power button to turn off my computer and turn it on again (reset button does not work).

i can't just run MultiBeast because i'm afraid my computer freezes while installing the drivers

So what is the problem?

Use XMP Profile 1 on BIOS.

Is the freeze happenig with any messsages on the screen??

Try booting with "-f -no-zp" then check whether the freeze happening or not.

i will try boot with "-f -no-zp" but i'm not sure if my RAM support XMP. does the XMP make Windows 8 unstable?

i set the XMP profile as Profile1 and booted Yosemite without boot flag. it won't recognize my video card and gets stuck on loading screen . second try. i rebooted my computer and boot with "-f no-zp". it works until i used it for 5 minutes and freezes. i rebooted my computer again and boot Yousemite with "-f no-zp" but it freezes after it recognize my video card and changed resolution to 1080p

i installed Yosemite on my external 1 TB HDD and connected to my pc with USB 2.0. is it the problem? if so, should i put my HDD in my pc and plugin SATA cable instead?

Better try with SATA connection.

Better try with SATA connection.

i tried with SATA connection but my computer froze. i rebooted my computer and type boot flags "-x PCIRootUID=1" but my computer froze again. i'm using the original Yosemite and not Hackintosh. my HDD is working fine and it's not broken. i unpluged other USB connection and disabled SSD and HDD but the problem still happen. is there any other solution for this?
