Windows NT Server Reboots Repeatedly

I have an NT 4 SP6a server here that reboots itself during the bootup process (bluescreen). Yesterday it had about 169MB of free space and for some reason today that was down to 3.39MB. I think one of our users had something to do with that, though she is senior management and cannot confront her about it.

This may be a resourse issue since it was running low on disk space, had maybe 93MB of free disk space (after unistalling a few appz) before the initial reboot that started this problem. This is the only thing I can think of that would cause this problem. Any other suggestions? I'm dying here.

What was the blue screen message?

Its the screen displaying "Windows NT 4.0 Service Pack 6.....256MB RAM" Then a whole bunch of text is displayed but cant make it out because it just shoots by and then reboots.

It turns out the problem was with mirroring array. The mirror drive was removed from the server and it booted fine. I think (hope) I just need to recreate the array. Problem solved for now, gotta go trick or treating.
