I'm writing from my husband's LAPTOP because my desktop is completely dead.   

We were out of TOWN for several days and when we returned my desktop was running very slow so I attempted to restart it.  It locked up, I pressed/held the power button and when it restarted it attempted to run a disk check.  The disk check locked up and I had to press/hold the power button again.  When it restarted I got a blue screen ~ stop: C0000218 unknown hard error.

Sometimes when I attempt to restart it I get: checking file system on C:
file system = NTFS

When I attempt to restart it in safe mode, safe mode with networking or starting in last known good configuration I get . . .

MULTI(0)disk(0)rdisk(0)partition(2)\windows\appPatch\drvmain.sdb
multi(0)disk(0)rdisk(0)partition(2)\windows\system32\drivers\ . . . (various items)

Now it won't start, not EVEN in safe mode.  Everything I try ~ I just get a black screen.

** I just tried to restart AGAIN and it ran disk scan, said it had completed disk scan and would restart, the screen went black when it attempted to restart and the screen is still black and it won't restart.

What can I do to get my computer BACK?

Any help will be greatly appreciated!you should not post twice , you will not get help any quicker , harryI didn't know I posted twice and certainly did not mean to.  We're also having some trouble with husband's laptop and it must have posted twice when I hit "refresh."  Feel free to delete the duplicate.

Do you have any advice/help for my problem?
