Hello Experts! I have a problem booting up my computer as in no beeping sound, no display even the POST, even the monitor power switch indicator light is color orange. But the CPU's powers supply is working and I know that there is power supplied for the computer. The first thing I notice is that the CD ROM's light keeps on blinking. I assumed that there is a CD inside that might have caused the problem, so I pressed on the eject button. I did not found any CD in it but, suddenly the computer started to bootup...WEIRD!!! (CD ROM tray still open) The computer started normally but when I to closed the CD ROM tray the computer shuts down automatically (making it on its state as I described above). I opened the CD ROM tray again and the computer started again but this time I went to CMOS set up to check the settings. I set the configurations to "Optimal Settings". Saved the new CMOS settings and restarted the computer, still no development. I still need to open the CD ROM tray in order to boot up properly. By the way, my mother board is an ECS P4S5A. Next thing I did was to change my IDE cables. Instead of making CD ROM drive as a primary slave, I changed it to Secondary Master. Same thing with the jumper settings. Started the computer but still no effect. CD ROM tray should be open in order to start the computer properly. I ended up removing the CD ROM drive, now my computer boots up properly unfortunately without a CD ROM.
I tested the CD ROM drive to other working computer and it worked fine. I even installed programs using it. Other working computers did not reacted good. With the CD ROM drive installed, cmos could not detect the hard drive. WEIRD!!!! I removed the CD ROM drive and the computer started properly.
What could be the problem? I think its the CD ROM drive. I just dont have an idea on waht part of the CD ROM drive that cause the problem.
If not the CD ROM, what could have cause the problem?
