There can be many possible causes for your "black screen" problem when attempting to start Windows normally, so let's start with a few of the most basic options:
Try the following ...
Why 10 times? Based on past experience, a successful result is sometimes achieved after several consecutive failed attempts.
- Start tapping the F8 key after you press the ON button, and continue tapping until you are presented with the "Windows Advanced Options Menu" screen.
- Use the UP/DOWN arrow keys to select "Last known good configuration", and press the <ENTER> key.
- The computer will attempt to load Windows.
- If Windows does not start, try the same thing again .... and continue trying for at least 10 times, before you rule that option out as a means of getting your OS up and running again, normally.

Check that your hard drive is not failing. On a working computer, download the diagnostic utility from the hard drive manufacturer's website to create a bootable floppy or CD.
- Find the brand name of your hard drive. You will find this info on the label of the hard drive (most likely you will have to remove the hard drive from the box to read the label). You will also find sufficient info to identify the drive (the model number) by looking at the hdd code in the BIOS Setup Menu, and then googling the code. Another alternative is to use something like Everest or Belarc Advisor.
- If you have trouble identifying your hard drive manufacturer, use the Hitachi diagnostic utility: It will work with most hard drives.
To make a bootable CD, download the .ISO
image to your computer. If you don't have a suitable burning program, download ImgBurn
and install it. Open ImgBurn
, and choose to "Write image file to disc
", and then navigate to the .ISO
file that you have just downloaded. The completed CD will then be bootable.
Boot the afflicted machine with with the CD that you have just burned, and run the short/quick test and then the long/extended test. If the hard drive tests show NO problems what-so-ever with the hard drive, then it is safe to proceed with more work to rectify the problem with the Windows system.Note : If you do not know how to set your computer to boot from CD, see the following link:How to Set BIOS to Boot from CDROM
If there is no problem what-so-ever with the hard drive ...
Use the Windows Error checking utility

- A message will notify you that a restart is necessary: Click OK, and close all windows.
- Re-start the computer. The disk will be checked when the system boots.
This test will take some time to run and at times may appear stalled but just let it run.
- When the disk check is complete, the system will re-start automatically and load Windows.
- If any errors were found, or repairs made, re-start the computer a second time.
- If any errors were found, it may be prudent to repeat Check Disk.
