Hi,

References to Vista also apply to Windows 7.

Saving any needed data and re-installing Windows 7 might be the best option though here are a
few others. See "How to do a Repair Install" info below.

--------------------------------------------------------------

Can you access Safe Mode? Repeatedly tap F8 as you boot? If so you can try Control Panel
- Device Manager - Display Adapter - Double Click on - Driver tab - click UPDATE driver -
then Right Click on Device and UNINSTALL - REBOOT.

Another method to try to access the desktop (try in both regular Windows and Safe Mode)
is to CTRL + ALT + DEL and on Process Tab find EXPLORER.exe and END PROCESS on it -
then on Applications Tab - lower right - New Task - type in EXPLORER.exe . Safe Mode is
reached by repeatedly tapping F8 as you boot up.

First check this thread in case its a simple one and if not come back to this thread.

Black screen issues are extremely tough to repair and any fix is usually on a hit or miss
basis. That there is no information on a black screen like there is on a blue screen just
adds to the difficulty. Often using a restore point nor startup repair will have any effect.
You can try a google to see suggested repairs some of which have worked however these
cover a wide field of efforts.

Here is a video of one fix.

Do you have a Window 7 Disk? You can try System Restore from it. If you do not have the
disks your system maker will sell them cheap. Or try from Safe Mode if you can get
there.

You can create a Recovery Disk or use someone else's same version (to do the System Restore
it only has to be bootable).

These require the correct Vista Disks since you can't boot to Safe Mode.

Try Startup Repair -

Another method that sometimes works : In the Command Prompt of a Vista boot disk type :
(type one line or copy and paste one line at a time and then hit enter - do not type
parenthesis or BOLD
)

c:

cd\

cd c:\Windows\System32\winevt        (there is a space between cd and C: )

ren Logs LogsOLD                             (there are spaces between ren and Logs and Logsold) 

REBOOT to Windows

Hope this helps.
