after putting a new power supply in, my PC finally has power. however, computer "starts", I get nothing on the screen, ever. I hear everything whirling around, the PCM fans move. I disconnected everything (floppy, hard drives, etc.) power is just going to the motherboard, that's it. same result.

new unit

the one that splits off and goes to the motherboard? yes, I did plug it in, for mine, it powers the two ECU cooling fans, when I disconnect it, the fans go off.

After looking at the referenced post.... your old power supply was putting out 22 volts instead of 12. The possibility of the voltage regulator on the motherboard also being burnt out is very good.

Look on your motherboard for any capacitors that look like the top has popped up on them of has popped up and has some black "goo" coming out of them.

If you find any that exhibit this conditon, you have two choices. Replace the motherboard or possibly find someone locally that can replace the defective capacitors and try the board again with your new power supply.

Good Luck,

P.S. I have attached a photo of what "popped capacitors" looks like.

thanks for the reply. i'm an ase certified ford tech, and in our line of work, there are those kids fresh out of school and the stupid techs that can replace parts and figure out problems by chucking parts at the problem and eventually hitting the jackpot, and those good techs that can step by step diagnose an issue and replace one part and be correct.

in the computer world, I'm the parts replacing monkey who just shotguns parts at the problem in the dark, I admit it.

so...

much like the other guy did in the other thread, can anyone link me to a selection of motherboard/processor combinations that would suit my needs. basic word processing, basic internet explorer, TONS of storage space and image processing capabilities (my new rig is 26.6 megapixels per shot...), and even some light gaming (I'm talking like java applications online, facebook poker, etc.). budget does not matter, I'll pay what I need to pay.
