My computer SATA interface ““`~

My computer can not detect the regular hard disk, (the hard disk did not voice) every time when a new SATA ah fixed-line data can be used with, and then I will do so, I bought two SATA data back line is still the same effect, I Onda is on the main board A78GT six SATA interfaces, I have tried all the testing can not, then I play him dozens of times, but also over, each time into the computer after 10 minutes before the special card, this is not the case previously, On the back slowly returning to normal, and then I heard a few hard as it is washed off the kind of electric sound, a few cards and a normal, I do not know how the case ah, it would be a power / (power is HuntKey Wang cool 1.3)

should be delayed start to set too short a time as 4 seconds set up to try to determine whether there is a hard problem, Proposals for a new block of a try.If it appears there may be the motherboard SATA interface has a problem! This problem is very difficult in general.
You can try another SATA interface, or, if so, we would like to say that the interface is not a problem.Sata Since the line is new for you, that line can not be a problem.And then Can think of the questions are as follows:1 power 2 other motherboard components 3 small hard disk drives 4 circuit board inside the shaft aging, and so on ……..

So the question suggest that you find a computer repair, take What gave you the multimeter Test, and so on-line to ask not say.
