Hi Competition, It might be an issue with the software or the hardware of the computer. You may try the following steps and check if it works. Drain the residual power from the laptop: I would suggest you to run the on-board diagnostics to check the hardware functionality: If the diagnostics pass without any error, then try booting to safe mode and check if the system boots to the desktop: If the system works in safe mode, perform system restore. Please reply if you have any questions.
I too have attempted to use the options mentioned in these posts and still nothing is working.  When it turn on the PC, I get the screen with the two options to either restart normally or let Windows try to repair the PC.  Neither one works.  I am becoming very discouraged at this point.  I keep hoping someone will post a solution that is easy to follow and solves the problem.  I don't believe my laptop came with back up CDs/DVDs.  I haven't tried calling Dell or Microsoft yet.  Has anyone been able to find a solution yet?  Thank you in advance for your time.  By the way, this just happened between Sunday night and Monday morning.
