Thank you for all your help. I just got a replacement of my motherboard and hard drive from Dell along with labor for free today, since my laptop is still under warranty because it is only 6 months old. Too bad I did not read TorrentG's post before I contacted Dell to replace my parts, but at least I got a free replacement and labor. But, I am still interested in finding out how TorrentG found the culprit. I am not sure if that is the culprit, since I did not get a chance to try it, but I am a computer science major, and I wish to find out how to solve the problem if it occurs again in the future. However, I will not be able to read the post until Sunday because I am going down to Mexico tomorrow, but please post it. For Saltgrass, when Dell replaced the hard drive, and powered on the laptop, everything just went back to factory defaults. They did not have to install any disks or anything. For the both of you, it would be great if you could delete the energy report and/or system information from your earlier post and/or computer if possible, since it might contain personal information. Thank you very much for your cooperation in advance, and for helping me solve this problem.
