Black screen after welcome in vista home premium

[Guest]

came home from work today and turned on system. it boots to welcome screen
and then goes black with a movable curser. Ihave had vista for 2 months
without a problem until. now. I did the start repair off disk, still
nothing. cant even get into safe mode. Thanks in advance

Ok, so you've tried using your restore disk and 'repairing your computer'
doesn't work?

As far as getting into safe mode, holding F8 while the comp. reboots gets
you to where you can select it, if its doing the same as not going into safe
mode, it sounds like your boot configuration is screwed, in that case since
'repairing' isn't working, you may have to reinstall vista if you don't have
a boot disk.

As an alternate, do a system Restore to an earlier date.
