I made the mistake of installing Windows 8 Consumer Preview and the only way to wipe it was to completely reinstall Windows 7. After reinstalling Windows 7 and deleting one of the partitioned drives, I have been experiencing problems with my display.
The laptop will boot up and show the Dell logo for a few seconds and then the screen goes blank. The laptop works if it is plugged into an external monitor. I don't believe it is a hardware issue because the screen will be crystal clear for a couple seconds and flicker before then going blank. I have updated the video drivers as well but didn't fix the problem.
After doing a Google search, it appears that a number of people have the same problem as I do. This link includes a detailed description of the same problem. http://answers.yahoo.com/question/index?qid=20110925214522AAEM8g1
Any suggestions on how I can fix this problem?
