HELP - my XPS M1330 has been working fine until I turned it on yesterday morning.  It shows a brief windows screen and then a BSOD leading to an infinite reboot loop.  Safe mode says "CRCDISK.SYS" is the last driver attempted so I am assuming the error is there.  All attempts to system repair/restore have failed.  I have not made any hardware or BIOS changes, but my Zune was plugged in and an Adobe Updater may have been running at the time of shutdown.  Any ideas?
