PC not powering up, any ideas?
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

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.

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.
