computer No Post: CPU, Mobo, PSU,..?

"with having to leave the computer plugged in for around 15 minutes." Probably was a bad capacitor.

Yeah I think that old Antec is having such problem. New one is not.

Here is my update of the problem:

I believe it's fixed as I am able to run both old and new components without problem. The trick is: don't use the case's power switch!

My friends and myself still don't believe the little case power switch can cause such a problem but my desktop is running fine without plugging in the case's wires.

- With the MSI mainboard (with ATI Radeon 9500 videocard), I have absolutely no problem at all.
- With the new ASUS mainboard (with Geforce 6600GT videocard), I experience some No Post problem when plugging in new components. Removing the videocard and inserting in back again or few turning ON/OFF would resolve the problem.

Both system configurations are still using the old CPU but with new PSU.

For far so good. It is running smoothly only a bit irritated for having to use a metal to short the 2 Power-Switch pins on the mainboard to turn ON/OFF.

I too have known system simply to not work when in the case, and be fine otherwise. Someone suggested that the orientation of the power and reset switch connectors can be important as the ground side can sometimes be connected to the case. Dunno if it is true or not, but you could try reversing the connector.

Since then I've always followed the priniciple of the little triangle mark is +, and have never tested the theory.
