memory behaving weird

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

Are you sure you don't have a BIOS setting that says your system should sleep after a given amount of time?  It may not have been the other memory, but shutting down the machine and starting it up again.

Sorry that I didn't reply sooner. I was on vacation from my work and I had no access to internet.

Even if it was the BIOS' power saving function, it should come back on when I press the power button of the PC. I even make sure that I turn it off by unplugging the power cord. Then I plug it back in and press the power button, but it just didn't want to start. All I see are the lights and the CD-ROM that can open and close. Nothing on the screen until I put in another memory.

That certainly doesn't make sense - there could have been some other component failing, like your power supply, combined with a surge or voltage drop in your house.  Putting in a memory from somewhere else when your memory had nothing wrong with it should not have caused a non-working system to work.  Having other simultaneous problems that you didn't know about seems more reasonable to me.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

But the thing is, I didn't test anything else, but just played around with the CPU and the memory. I didn't even touch the power supply connections.

Now the PC works but now and again, it freezes, and then when I restart it refuses to come back on. I had to do the same thing, reseat the memory. Only this time I don't have to borrow the other memory.

Try cleaning the contacts with an eraser - that might be the reason taking memory out and putting it back in would cause it to work.
