Hi guys,
I installed mavericks successfully on my amd PC
The Kernels that I used are amdfx -v and i installed it successfully
now when reboot my system i get the apple logo with the spinning circle but after some time it gives me black screen

My specs are
AMD FX 4100 Quad Core 3.6 GHz CPU
ATI Radeon HD 5770 GDDR5
8 GB of DDR3 RAM
MSI 970A G45 Motherboard

I installed it several times and every time i get a different problem
the first time i installed it i had a kernel panic but after deleting a file called appleintelcpupowermanagement.kext it gave me this blank screen after the apple logo :( 
what should i do ?

Your mistake is that OSX doesn't support AMD. That is why you are having this issue.

Would you be so kind to boot with the -v bootflag and report me the error?

Please, also try to boot with GraphicsEnabler=No and -x.

Do you have a bar under your apple logo? If so, this has happened to me before to. All you need to do, is hold down cmd + r during boot up (when the apple logo is on the screen) and then there should be three options:
1. Reinstall maverics
2. wipe hard drive
3. Go back to a time machine back up.

This only works with a problem with the hard drive though.
