GA-P55-USB3 Windows 7 64-bit crashes on startup.

Do you have your hard drive plugged into one of the blue GSATA ports?  Because that's where I have it plugged in now, and it hasn't had a problem so far.  (Starts up a lot faster too!)

That will be the Intel ports the blue ones as a posted from the start saying that...by me...

Ah, sorry-- Got confused.

[Dark Mantis]

You are confused  

Which ports are you using?

[melanierw]

I am currently using the white port labeled GSATA

[Dark Mantis]

They are actually the slowest ports on the motherboard! When we did a test on the various ports a little while ago the GSATA came bottom of the list folowed by the SATA3(Marvell) and the Intel ICH10R southbridge controller was the fastest.

Heh, well for what ever reason, the computer will start up successfully when it wouldn't in the other ports.
I'm just thrilled it seems to be stable!

[Dark Mantis]

We are all delighted for you, I am sure. It's just it would seem to be the opposite to what you would think. It might be possible that you have a problem with the Southbridge chip because that should be the fastest and most stable.

Hm, well to be honest-- I don't know what the Intel ICH10R southbridge controller is or what it looks like... Originally I had tried the SATA2_0 slot, and that was when I was having problems.  (I was thinking numerically that "0" was the place to start)  Now, I have it plugged into GSATA2_7.
(If there's another option, I have to admit that I don't know what it is)

[Dark Mantis]

Nothing wrong with your logic port 0 was a good place to start and should have been the best result for you but for some reason wasn't. The first few ports are all controllled by the southbridge. Anyway the main thing is it is working ok for you now.

[melanierw]

Well, in any case, thank you all very, very much for all your help!
This forum is a great place!

Hello,
Not sure if anyone will get to read this, but I would like to thank Elrin, Melanierw, and Dark Mantis for the helpful posts. This particular post caught my eye because the system specs are almost the same(different video card).  I replied to this post since there did not seem to be other posts like this one after doing a search. Also, to confirm that there is a problem with the SATA vs. GSATA ports.

I too had the issue about Windows 7 hanging on the startup screen. The solution was also to switch the SATA connection from SATA2_0 to GSATA2_7.
This problem occurs for all of the SATA2 ports(0-5).

I have now spent a total of 8 solid hours trying to figure it out, all the while believing it to be the classpnp.sys problem that other Win7 users have run into.

The annoying part about this problem is, as Elrin stated, when you switch the hard drive out (put in another computer/ put a working hard drive into this computer) it works in the SATA ports! Something about this motherboard REQUIRES the user to have hard drives which had their operating systems installed on this motherboard to be connected to the GSATA ports.

Edit: I tried installing Win7 32-bit.

Well hi and welcome to the Gigabyte Forum.

Thanks very much for the input and feedback as it might well help someone else in the future.
