computer is not able to start the BIOS

September 6, 2010 at 23:44:32
Specs: Windows XP, Intel core 2 duo / 512 MB DDR2
Computer is not able to start because its not able to perform POST.
CMOS/BIOS is not starting.Nothing displayed on monitor when starting computer.

I had reinstalled XP then when i had reset BIOS by Jumper setting as per manuals...pc not starting.
i have Checked power supply . its fine.. RAM is also fine..
But when i m starting computer.. nothing dispalyed on Moniter.
Monitor is also fine..
I have checked motherboard without any IDE, HDD,RAM...
fan running fine....MO has not inbuild Speaker to check the beap sound...

Computer was working fine on previous day of problem.

What may be the exact problem?
Previously when i was starting pc, sometimes it was giving error as
"Verifying DMI Pool Data" error. but I think it may be due to bad sector.

I had checked CMOS jumper . it is at correct place.(Normal : pin(1-2))
When CMOS jumper is in CLEAR mode (Pin 2-3) and switching on power , cpu fan is not starting. & i think it may be indication of CMOS clear...

But when placing jumper to Normal mode... pc not able to start...
