I am experiencing a very strange problem. I have tried many combinations of install using iATKOS 5i on my eMachine T5048. I am using ps2 mouse and keyboard because I am having problems with USB mouse/keyboard. But randomly when I boot up into OS X. the mouse pointer will not move at all. I have to hit the power button and then that sometimes fixes it. It's very strange. I am unable to figure out the cause of this. It seems like the computer is in sleep mode or something and i have to hit the power button to wake it up. Or at least I think thats what its doing.

Ive tried enabling/disabling USB Legacy mode in my BIOS and that doesn't really seem to do anything. So I don't know what the problem is.
