I am using a Apple MAC, with MAC OSX. The machine is specified with Intel i7 processor. And along with that Gigabyte GA-X58A UD7 motherboard. In very short I am facing a problem in my machine, but does not know either this one for the motherboard or nay other hard ware device, but I think this problem should be for any one of the hardware. Ok now the problems rate, first one sometimes the machine restarts automatically, but this happens only in my machine while I was logged into the machine with windows platform, where as I also made a partition for windows vista. Another major problem is that, USB port in my machine is not working and this problem occurring after the installation of windows vista in my machine. So now is there someone from here can tell, which one is the cause of the problem. Is this for the hardware or not? Also suggest me some tricks to solve this issue.
