What is:

unknown device drivers is n900 or e71 cant remember so they not doing any harm

I have seen no evidence of this in the reports that I've looked at

The server {995C996E-D918-4A8C-A302-45719A6F4EA7} did not register with DCOM within the required timeout.

These aren't normally a problem. Post back if you still have issues with it after we've fixed the black screen.

FYI - black screens aren't easy to successfully fix. At work we've spent over 2 weeks trying to fix systems like this - only to resort to a backup/wipe/reinstall of the OS because we weren't able to fix it. As such our advice now is simply: Try System Restore to a point before the problem started. If you're able to get it working, then update everything immediately. Otherwise, backup/wipe/reinstall Windows.

Please post another, fresh copy of the jcgriff2 reports so we can see if there's anything else remaining to try.
