Hi,
You should be able to access the BIOS as you boot as that happens before Windows loads.
Start the computer and look at the screen for Setup/Settings - often F2 and press that. If
you don't do it fast enough Windows will attempt to restart so you may need to reboot and
try again. If you can't get to the BIOS there are hardware issues and you need to seek the
help of the System Maker or a real computer shop (one that does its own in-shop service).

Why is my screen black when I start Windows 7?

**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.
You can save your files by putting the drive in another computer or an
external drive case and then backing them up. Do so using several
methods in a redundant manner. Of course a real computer shop or
your System maker can help recover the files.
Or you could use an Ubuntu boot CD to back up the data.

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.
A method to try to access the desktop (try in both regular Windows
and Safe Mode) is to CTRL + ALT + DEL - Task Manager 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. CTRL + SHIFT + ESC also starts Task Manager.
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.
