PC Not Booting - What might have gone wrong?

[Kamlesh]

Hello,

Last evening when I switched ON my PC, its not booting.

SYMPTONS: When I power ON, the keyboard lights come for a flash and go
off. The monitor light keeps blinking. It reads all my Drives once
and stops. The keyboard locks (CAP/NUM/SCROLL) don't work. No
harddisk activity too. The CPU Fan works well.

TROUBLESHOOTING DONE: Till now, I have done the following
troubleshooting:
=> I have remove all the Add-On Cards (Display, LAN, Firewire,
Multimedia).
=> I have also tried removing the RAM. When I remove the RAM, it gives
me the BEEP. I have put back the RAM, and there is no BEEP.

SOLUTION REQUIRED:
What might have gone wrong? Can any hardware expert help me
troubleshooting.

PC Specifications:
- Intel P4 - 2.4GHz (with original Intel Motherboard having onboard
sound, display)
- 256MB DDR
- 160GB HDD
- 1.44" Floppy Drive
- SONY CD-ROM Drive
- SONY CD-Writer
- SONY DVD-ROM Drive
- GeForce MX-400 Display Adapter


Regards,
Kamlesh

Could be a dead power supply. Not enough voltage to boot. Could be the CPU
too. The RAM change being detected means the motherboard and RAM are
probably ok.

Try clearing the CMOS, sometimes this will let you boot if it's not the
power supply or the CPU that died.

Most likely either the power supply unit or the motherboard has failed. The
easiest place to start fixing it is to try replacing the power supply with a
known working one.

I took it to a Hardware Shop and got it rectified.
The RAM was the culprit. Got a new RAM and it worked.

Its really strange that my earlier RAM is not giving any Beeps, but it doesn't work.

Thanks,
