Computer won't boot

[Dwayne Austin]

I have a Dell inspiron 5315 that when it starts to boot up goes to a black sceen with !! 0xc 0000034 !! 250/91868 (_0000000000000000.cdf-ms)  I have run start up repair, and  chkdsk /r in dos from a recovery cd.  Neither one of these helped.  can anyone help me out?  Thanks.

What is new or different since the last time everything worked properly (ie, new hw, new sw, virus, error, etc)?

[Dwayne Austin]

there is nothing new but it did start an automatic Windows update that did not finish because of a bad connection if that means anything.

What OS?

[Dwayne Austin]

Sorry OS is Windows Vista.

Thanks for trying but this didn't work i've given up and am going to reset factory defaults.  is there anyway to back up my files from cmd prompt?

If you can get to a command prompt you can slave another drive (or use a usb drive or floppy) and try dos "copy" commands (ie, copy c:\documents\*.* d:\documents).
