Hello all, new to the forum, but looks like a good place to find some help.

My problem is pretty simple. My old IBM hard drive crashed, so I took my newer Seagate Baracuda 200GB drive that was for storage, and switched that to my OS drive, and added a 500GB Baracuda for storage (with various partitions).

Right from day 1, actually 2nd or 3rd day, I've randomly been getting blue screens that reboot my computer. At that point, my BIOS no longer picks up my Master drive, only the 500GB. So I get the "no operating system error" and hangs. Once that happens, the BIOS switches the primary boot device to the storage drive and of course XP isn't on it, so it loops.

The thing is, I've found out, if I turn the power supply power off and back on, and boot the machine, my Primary drive returns. All I do is change the HD boot priority back to the 200GB drive and it boots. The only noticeable problem is the blue screen which symbolizes to me, that the drive just vanished again.

I've got the latest BIOS for my mobo (ASUS A8N-SLI premium).

The tricky thing is when it's used for storage, it's fine. It's never dissapeared in windows or the BIOS. This has only happened as the primary drive, and actually, when I first purchased the drive, I tried to make it my primary drive and it did then, so I put it back to the storage drive and it worked flawless. Now I want it as the primary drive and I'm out of ideas.

Any takers!?
