WD Caviar Green 500Gb is not booted from time to time


So I have this HDD and from time to time it's not booted, recognized when turning on my pc. I got this issue for the first time a few months ago but I managed to solve it somehow, changed through the SATA ports. After all these months, I got this issue again... today.

I opened my pc and went on changing the SATA ports and it worked. However, the interesting thing is that I switched for instance from SATA port nr 2 to 4 and it worked for like 30 minutes. Then I switched back from 4 to nr 2 and since then it works just fine, 2 hours uptime, lol.

I don't know what could be the issue and I'm getting tired of opening the pc up and switching the HDD through all these SATA ports.

My motherboard is Asus M5A78L-M LX, socket AM3+

Would it be the motherboard? I mean I would want to change the faulty part, but I would want to know if to buy a new HDD or a new mobo...
