bsod on startup :( Options

[=R6= Raile]

yo guys

so last night my computer decided to bsod on me while it was just sitting at the desktop. Since then, it bsod'd about 5 seconds after loading the desktop each time I booted it. The first time I tried to boot in safe mode, it worked, however, the second time I booted it up, now safe mode won't work either (it gets to a black screen, with a mouse cursor, but just hangs there. even when booting in to safe mode with dos prompt only). So I'm kind of fucked. I've tried removing each ram stick and seeing if any of those are causing the problem. I've tried using the windows boot up disk (i'm using vista btw) to repair windows, do a system restore, and check for memory problems. basically I did every test the windows disk has to offer, and nothing worked. I'm guessing it's gotta be hardware? Though I didn't think it mattered, I pulled out my audio board anyway and tried booting but no change. It's the only thing I think I can unplug and test. All I've got left is the mb, graphics card, and harddrive. Any suggestions on how I find out what the problem is?

Cheers

very strange... obviously have a quick look to check whether X: for some reason is the hard drive and not the cd. If you do just "c:" in the command prompt and then "dir" what does it do? no error messages? The only other reasons I can think for not accessing the drive are either file table corruption, Encryption (such as safeboot) or recovery console not having loaded SATA drivers to handle the disk (not sure on vista if there is an option for sata drivers)
