I actually have not gotten any error messages at all. My computer simply stopped reading my CD drive. When I put a CD into the drive it would spin the CD up; act like the drive was being read for a minute, then the lights would go out and nothing would happen. When I clicked on the drive letter in explorer or via the run box it would simply ask me to enter a CD into the box. I tried cleaning the drive, etc, but nothing worked. Basically the computer stopped recognizing that the drive existed. I tried to use MSCONFIG's diagnostic startup to see if there were any specific driver issues, etc and when I tried restarting the computer in that mode it only got to as far as the blue screen before it stopped loading (It never started loading windows). I've tried letting it sit at that stage for an hour or so and it never moves, the orange light on the tower doesn't flickers, it just sits silent. When I press ESC when it starts to boot it shows me that the RAM passed, System/Virtual BIOS Shadowed, Mouse initialized, and it shows the "Fixed Disk Comment" and the hard drive is spinning. The light on the floppy drive never comes on during this process. If I press F1 while it is testing the RAM it says "loading" setup on the bottom of the screen, but never goes any further; thus, I can't get into any settings, etc. I've taken the entire computer a part, pulled the CPU chip out, etc. I can't find anything that is burnt, and it does not smell like something is blown. I did find that my CPU fan did not appear to be running. When I plugged the computer in with it partially a part the fan was just shaking. I gently spun it a few times with my finger and it "kind of" started to spin. So my guess is it basically cooked itself. I've taken the entire computer completely a part and reassembled it and I get exactly the same result. Absolutely no error messages. It just sits there and looks ugly. If you look at the standard of a computer boot process being divided into three parts 1. BIOS, 2. Windows, 3. Programs; I get mostly through BIOS, but I never reach the point where it starts loading windows. Checking the hard drive and initializing the mouse are the last two steps it displays on the screen in BIOS. Does this sound like it would be a CPU chip problem where I could just change that or is it more likely a motherboard problem?
