Guys my system is powering on,all fans and lights are working but it is not booting up.I cant see my BIOS too.No hard disk activity too (No HDD Lights).

System Specifications:

Biostar G41D3C LGA775 Motherboard
Intel E5200 2.5 ghZ Cpu
HD6670 GDDR5 Graphics
4GB RAM
1 tb WD10EARX Western Digital Green Hard Disk
Deepcool Alta Cooler

Problem Description

I have been experiencing this problem since a long time,it happened earlier too but after some shaking of Cabinet or restarting by reset switch it gets back on.But after some day it happens again.It happened the same thing now but this time it wont turn back on.
When I press the Power Button my fans spin and blue light of CPU lights but the red one ( H.D.D Led) remains silent,there is no display too,no BIOS nothing.Basically it just powers on but never boots in reality.

Stuffs Tried



  • I tried that 30 second method,pressing the power button for 30 seconds after detaching all the cables from the Cabinet,but it changed nothing.

    I tried resetting CMOS by the CMOS switch,but it didn't solved either.

    I tried taking everything off from motherboard and cleaned it and hooked it up back.

    I tried taking all the components off and putting it back one by one,Still nothing.

Observations


  • When I hooked everything one by one,even when there was only motherboard,CPU,PSU and RAM,there was still problem in starting up (so I might blame CPU or PSU or Mobo).

    There was no beeps heard by me.

Thanks Guys! Please help me out and suggest me solutions to get rid of this problem.

Have you tried removing your CMOS battery and replacing it with a fresh cell? I'd ask you to look into the troubleshooting guide linked below this post but in retrospect I think you'll need to look at your powersupply which is powering your system(and is considered to be the heart of said system). Speaking of which you might want to include your PSU's make and model number.
