I left the PC on for about 30 minutes for it to process something, when I came back I found it turned off. From since it does not want to boot, but it does show that it has power by the lights when I turn on the switch. Even the CD-ROM drive can open and close. I reseat the memory several times and it does not work. I even reseat the CPU, and nothing. Then I borrow my friend's memory and insert it into the PC. It worked! It went into Windows and all. Then I decided to put back in my memory. Well, while I was surprized to it's reaction I say to my self "what do you know". The PC is back up.
What I want to know is what's causing it that it does not want to work until I plug in and out another memory into the system.
Thank you expert
