Hi,

Do any fans spin? are the drives starting up? If they are try another video card.
Are there any beeps?

Are you sure the monitor is good.

Is there a onboard video card? if so try connectting the monitor that that.

And maybe you can give some feedback on Rick's questions. Then we can might help you better.

My first guess would be bad video card 2nd would be bad psu but they are only guesses.

Here is what you should do to try and eliminate as much as possible before purchasing a video card or psu.

Remove everthing but cpu, hsf,ram.
Remove mobo from case and place on a piece of cardboard
Install only cpu with hsf
1 stick of ram in the correct dimm
video card
Psu making sure the 20 and 4 pin connector are attached
Case speaker making sure the + and - are correct
Case switch
Mouse, keyboard, monitor
Verify all jumpers on the mobo are correct
Verify the cpu fan is on the correct header on the mobo
Clear the cmos by switching jumper from pins 1&2 to pins 2&3 and waiting 5 minutes, then make sure to replace jumper to pins 1&2

Now power on, what you want to do here is get a post and be able to get into bios.
If you can it could have been a case short or one of the removed components or as simple as a jumper setting or connection not good.
If you can not you would have to try the video card in another computer to test. There are ways to test the psu but we can try that if the above fails so post back your results.

Well then we know it ain't the video card, I would try the above or if you don't want to go thru all that you could try another psu if you have one that meets P4 specs.

Just thought of another thing, could you tell us the power supply make and its watts and amps on the 12v 3.3v and 5v , this info should be listed on the psu.

I am thinking that if you upgraded maybe it ain't powerfull enough for the new system.

I don't think that psu has enough amps on the 12v and 330w is kind of low for that system.

If it does not have a 4 pin 12v connection fron the psu to the mobo then it is no good, this is in addition to the 20 pin.

What we know,

It should not be the mobo or cpu because you have tried different ones.
You tried the video card in another computer and it works
You are getting no beeps with a case speaker hooked up to the system so I am assuming this is not the ram.

This only leaves the psu.

If you try all my suggestions and it still don't work purchase a new psu, I recommend Antec 430w true series. Stay away from cheap generic psu's

I normally don't use any chat messengers I use the board to post trouble shooting procedures sorry

Yes it is possible to get a 450w or 500 w and probly better just stay away from generics

Antec 480w true is good and 500w Ulta Xconnect is also good I use both of these.
