Computer runs completely laggy even in bios

[adkap2]

Hi all I am 15 years old and I am currently building my second hackintosh. I just got my computer case for my ZZN Build. I had all my parts a week before so I ran a test build on top of the motherboard box. I even Installed mountain lion on it. Everything worked perfectly. Now that my case has come today, I installed everything into the case. For some reason It boots up but everything is really slow and laggy like say the chimera boot loader is very laggy on the time in and moving the selection with the arrow key. Also it will lag when i move around in the bios all with my wired keyboard. Later My computer finally boot and the mouse wouldn't even show up everything was flashing. None of this was happening before I put the motherboard in the case.

figured out with trial and error that the problem had to do with the targus bluetooth dongle off of custom beast. I have no idea why but thats the problem.

Well done for tracking it down. I tried many Bluetooth dongles before I gave up on them and installed a genuine "Apple bluetooth module" have look here if you are interested
