When Starting my pc I'm facing a problem.

can you at least get into the BIOS settings?
usual access is via Del, or F2, or F10, or Esc as the PC first starts up.

try removing the memory sticks and graphics card (obviously adjusting to your actual hardware).
with a soft bristled brush, wipe their circuit boards, their contact points and the motherboard slots they go into.
reseat the graphics card and one of the memory sticks.
try that - if not luck, try another memory slot.
if still nothing, try another memory stick.

if you CPU and motherboard allow it, remove the graphics card and use the onboard graphics.

if none of that works, you have either a dead power supply or motherboard and will need to either take the rig to your local PC repair shop, buy new parts, or get your hands on some so you can test where the actual fault lies.

@ULTRA RAUNAK - any news?
