Hi all,

My pc is not powering up anymore.

I have tried everything that I know but to no avail.

I have replaced the power supply.

Still will not power up.

Please tell me what could be wrong. Many thanks in advance

Some things to look for:
- motherboard shorting on case, or dust accumulation
- CMOS jumper set to CLEAR, instead of NORMAL position
- bad connections
- extra power connector not attached to motherboard
- faulty or inadequate power supply
- bad RAM, or wrong ones for your motherboard, or bad RAM slot (try in another slot)
- faulty video card
- bad motherboard
- bad cpu

Give some more details - how old is the PC, and what happened to the machine that may have caused it to fail?
The problem can be narrowed down if we know more.

ok, thanks very much for your patience.

How do I verify the following:

- motherboard shorting on case, or dust accumulation
- CMOS jumper set to CLEAR, instead of NORMAL position
- bad connections
- extra power connector not attached to motherboard
- faulty or inadequate power supply
- bad RAM, or wrong ones for your motherboard, or bad RAM slot (try in another slot)
- faulty video card
- bad motherboard
- bad cpu

Maybe difficult to verify video card at this time since it is not powering up but any pointers on hwot to re-check those points you raised?

Remove the motherboard from the case and set it on a cardboard box.  Keep the cpu, one module of RAM, and the video card installed and power it up.  If it works, you can add components back one at a time to see what causes it to fail.  If it doesn't power up, you need to isolate which of power supply, RAM, video card, motherboard, or cpu is the cause.  You do this by swapping them out for another one that you know works.

you can also test components on another PC, if available.
i recommend the same as Callandor, but for starters (without dismantling the whole system),  you can :
-disconnect all disks, and cd drives (also power connectors)
-try with 1 ram stick, if there is more than 1, and swap it.
-remove  all PCI cards
-test with another video card.

sorry guys, I seem to have ignored this thread and all the great help you gave.

I apologize for it.

I couldn't get it to power up. I guess I will have to replace the m/b as that is the only option left for me.
