Nice work trying to help here, Holdum.
@hashir: Can you please post back the exact Make/Model of your computer for us? (Dell Inspiron 1545 for example). Also, if you can provide additional specs on your hardware that would also be helpful. We are asking that, because if you follow Holdum's various suggestions to the end, you still may not get it to work if you have failed hardware (such as a failed RAM stick or hard drive). Additionally, and this is optional, you can go to
piriform.com and download the free
SPECCY diagnostic program. Select to output the result to text file, and post back here for us gurus to look at. We will then have a better picture of your hardware environment with which to troubleshoot.
Once you provide us with the specs on your specific computer, we'll be able to better assist you. Also, if you do solve the problem along the way with one of Holdum's suggestions or something else you uncover on your own, please post back here so that we can share your final solution with other forum members looking for solutions to your particular problem.
If you require specific instructions for testing your hardware, should all other solutions fail, we will provide those to you at that time for your specific make/model computer.
Best of luck,
