Gateway Desktop with amd phenom ii x4 qu...

Specs: Windows Vista Home
330 watt Power supply went out, fried? don't know why(factory) and I replaced it with a Thermaltake TR2 430 watt supply and a GeForce 9500 GT Video card. I fired up my computer and monitor states "no input signal" I put all back together original & barrowed an identical power supply from a friend and the same thing happened. Changed the flat screen HD monitor to a CRT and the same result. What has gone wrong? Installed power supply in another computor with no issues. Someone help, please.

Off the top of my head I am thinking psu took the motherboard with it. Are you 100% sure the psu is bad?

"Installed power supply in another computor with no issues."
Which one, the new one or the old? Just for giggles try reseting the cmos. I doubt it will help but I have seen stranger things. Did this computer have onboard video before you added the GeForce 9500 GT Video card or was it a different vid card? If it was onboard remove vid card and connect monitor to old connection on the board see if anything different happens.

I want to go like my grandfather did. Peacefully in his sleep. Not screaming at the top of my lungs like the passengers in his car.

1. Un-install onboard video driver
2. Return shared memory to ram & disable igp (bios)
3. Set initial display to pci-e (bios)
4. Connect the monitor cable to v-card
5. Install v-card driver

*geforce 9500gt sucks for gaming.

The Gateway came with a video card, I tried putting the old video card with same results, no input signal.

Yea, the old power supply would kick off with an audible "click". Took it out of the computer to see if I could fix it, like I have done in the past with other machines. While on the bench I heard a sizzling noise and then there was smoke. The old power supply was taken out of the computer before the serious crap happened, I hope.

I'm not much of a gamer any more, I do work apps mostly with my music running or I watch movies on the net, and furthering my education. Need the p'ter for work mostly and really can't afford another right now.

Kids got into the shop, and made a mess. I didn't catch them, except on there way out. Computer looked OK I'm really good at taking things apart and putting them back together, I just don't understand right now what the problem is.

And I don't know how to dis-able or in-able igp or pci-e and can't find much help on Gateways site at all. So I'm in the forums asking. Unfortunately for me and who helps me, at this stage, If you all will, info needs to be simple, but detailed. And I'm looking for a book. Praying the motherboard didn't get hurt.

I used an adapter for the card to hookup an old CRT I have with no luck.

When you first start the computer do you hear any beeps? If so how many for how long? If no beeps I bet either processor or motherboard. Sorry.
