Random boot problem, missing drive

ASUS P6X58D-E motherboard
Windows 7 64 bit
Core i7 processor
Corsair 750 Watt power supply
WD Raptor 74GB
WD Velociraptor 300GB
OCZ Vertex 2 120GB
6GB Corsair Dominator RAM
HD 5870 graphics card

I built this system a few months ago, and it worked great until recently. The problem started where Windows would boot up normally, but my E storage drive (WD 300GB Velociraptor) would "disappear" and not appear in the library as an available drive. I opened up the machine, checked the connections and all appears well. But it is still doing this "missing E drive boot" about 50% of the time. I don't know where to start......mobo problem? drive problem? Windows 7 problem?

Today, the problem got slightly worse, or perhaps it is an unrelated problem. The computer now hangs on the mobo's splash screen after loading "ASUS express gate." I had to shut the computer down about 3 times before I could get the computer to get past the splash screen and boot Windows 7.

Any advice appreciated.

Thanks.

  1. Sounds like the HDD might be crapping out, chkdsk. Do you have windows 7 partition and the 100mb system reserve on the same physical drive?

    No, I have each drive as its own partition.

    Is there any way I can definitely determine that is the hard drive failing? Is there a test or something I can do? I think it might still be under warranty.
