Mom's monitor wasn't displaying anything when the computer was turned on. My first thought was that the monitor was bad. So I grabbed an old CRT and headed over there. However, when I unplugged the monitor from the computer the monitor displayed, "Signal lost". Meaning that the monitor was good and also indicating something serious is wrong. I gave a big oh no! One thing that intrigued me was that the top cd drive kept flashing as if trying to access a cd. I took a pin and pushed it through the hole to get the tray to pop out. There was no cd in it but it flashed anyway. Then I thought I would reset the cmos. But Mom couldn't find the jumper that came with it.
I then started thinking about the hard drive and the OS. Now I don't know much about this stuff and work with what little knowledge I do have. I remembered that when a computer is first turned on the OS checks the peripheral devices to see if they are okay. Then I thought, is the OS getting stuck on that old CD drive. So I unplugged the cd power and data cables. Yessssssssssssssssss it worked!
One happy Mom!!
