My whole computer keep restarting just now and it was the scariest moment of my… week. I just restore a back up from my other hard disk and I was reformatting the back up hard disk. During this period of transition. I don’t have a full back up.

And when my computer just keep restarting at boot up without even loading to Windows Vista, I panicked. There was nothing on screen, it just restart and restart every second! I wanted to call my expert friend to help but I figured he would blame me for purchasing Windows Vista instead of Windows XP. So I start unplugging all my wires and open my computer up. I shifted the RAM, shifted the video card, even pat my hard disk twice.


It didn’t work and soon I was pretty sure the problem lies with the motherboard. I almost wanted to just go to the repair shop to get it fixed fast. There was then when, by some mythical chance, the motherboard manual – ASUS P5K bible – was left open at page 2-24.

If you’re really geeky, you’ll know that page 2-24 is about jumpers. Says book 2, chapter 6, verse 27 to 34:

Clear RTC RAM (3-pin CLRTC)

This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. You can clear the CMOS memory of date, time, and system setup parameters by erasing the CMOS RTC RAM data. The onboard button cell battery powers the RAM data in CMOS, which include system setup information such as system passwords.

Well, as we all know CMOS stands for the Canadian Meteorological and Oceanographic Society, it is certainly not the thing you want to mess with in your computer. But you know, I was feeling a little adventurous that minute and my hands just went to unplug the battery and flip the jumpers.

And oh my god, my computer came alive!

[CMOS also stands for Complementary metal–oxide–semiconductor.]
