How to solve a boot problem

[sonu2384]

Hi guys,
I am facing a peculiar problem with my PC. It is a P-IV, 1GB
RAM , Intel 945 GC motherboard. The problem happened that One day
Suddenly system stop responding . so I restarted it. But to my
surprise It failed to boot. It doesn't even showing BIOS setting
screen.
I tried to diagnose it by removing RAM, disconnecting peripherals
including HDD and optical drive.
But nothing helped. Is it MB failure? Or, some GPU problem?

Can some one help me? My MB is in warranty.

Thanks

The first suspect is always the power supply. The second is the mainboard.

Lots of past posts in this group on how to test a power supply.

Best method is to replace it, as any other method can only tell you that it
MIGHT be good. (but not tell you for sure, if it's good) -Dave

try a different power cord.
