asus m4n78 pro sata port not working

As per title. I got this problem just recently. The sata port seem to.. deteriote in usage for some reason. I could boot into windows, then after 10 min it will hang, crash, reboot, and all sata drives not detected, including my dvd rom. But if the cpu off for a few hours, or change the sata connection, the sata drives would be detected back and i can boot into windows again. But then 10 min later the same thing happen. I've flashed and updated the bios, reset the bios setting to default, clean the sata port with ethanol (suggested from asus website), i've tried everything. I checked all the cables, the sata drives all working perfectly, it all comes down to the sata port there. Does any know how to fix this? I know someone will suggest pci sata card, i've tried this, but the mobo bios wont let me. There only 3 options to boot, hd, cd dvd rom and floppy disk. It wont detect the pci card. I really wanted to fix the sata port because the motherboard is still in good condition. Nothing burn, no dust.. clean and pristine like. It seems kinda waste to change another motherboard. Does any one had this problem with m4n78 pro motherboard before?
Btw i use windows 7 but i dont think firmware/ driver conflict is the issue here. Been using for a year now

  1. I think it maybe the ahci driver problem like the intel p67 motherboard.
    Your MB has the NVIDIA chipset and do you try to install this NVIDIA ahci drivers from the asus website? click the "others" subtitle , even though it is old.

    Ok, i think this is the part i'm kinda stumped.. you see.. how do i install it in the first place? The sata hd only last like 10 min before it suddenly becomes 'not detected' back again. If i use for example, an ide hd, then install fresh windows with all the drivers and what not, would it be then saved into the bios to so the ahci driver would be working? Or i must install it inside the sata drive for the bios to recognise the ahci driver?
  3. 1) Download the ahci driver into the usb drive.
    2) Go to the computer management>device manager>click the TDE ATA/ATAPI controllers>right click NVIDIA ahci controller for update driver software>choice for from my computer>browse the USB, then update the driver.

    If you have other PC, download the ahci driver first, then do the update.
  4. It didnt work.. it doesnt have Nvidia ahci controller, instead it have sata 00 to 04, and ide 00 to 01. Was it suppose to look like that? When i tried to update them anyway, it just said the controller is up to date.
    Now my dilemma is this, i have 1 sata hd, 1 ide hd, and 1 sata dvdrom. Problem here.. if i wanted to install fresh windows.. well the sata port will hung me dry mid way.
    I dont understand, if the sata port is really broken, then how could it detect my drives in the first place, only to stop working a few minutes later?
    Is this kind of 'damage' normal for motherboard?

    I've tried this and then some more. First, i've downloaded the AHCI driver, and after a few tries, manage to get it in right up into the mobo's ass. Now the bios can detect the AHCI drives. Then my windows would load pretty fast, but a new problem arises. It gives me BSOD. Right after that, all the drives including the DVD Rom is not detected, again.
    Then, from another forum, i think the ROG forum, there are a thread which almost the same issue here, where someone suggested to uninstall the SATA driver so it would return to its default value, because the sata controller would load as usually, then wait for the new drivers to be install. Just as the same condition when a new mobo is installed. I tried method, but also no go.
    I actually dont mind to change another mobo, but the reason im persistent to resolve this, is because the sata drive COULD still boot up and enter windows like it aint no thing, only then hang after 10 min, stopped working and reboot. So, im confuse here whether this kind of problem actually kind of 'normal' for a mobo or sata controller per say. Because if it is, even if i have to change the mobo, i might want to consider ANOTHER kind of mobo instead of the same one which will only fall to same problem later.

    Btw im using Phenom x4 9950 AM2+ socket, with 2x 2GB DDR 880mhz ram, GTX 275 and Windows 7 Home Edition. If i am to change another mobo, what is better than this.. this sorry excuse of a mobo thing im using right now?
