I labeled everything, at least I thought I did, and now something isn't right. When I turn it on I get that high pitched squeal. The fans run, but I turn it off pretty quick after each try b/c I feared I might hurt it somehow if I left it on. If anyone has any ideas, or if anyone has an example of the power source wiring, I would be forever grateful.

I'm beyond frustrated at this point, b/c I've searched everywhere, then I wasted about 1.5 hrs. waiting and talking to Dell 'tech support' :thumbsup: to which the fellas answer was, "I need to reboot my system, can I call you...", then he calls me back with, "you should check dell.com/support." Gee, thanks fella, I would have never thought of that!!! :flowers:

Thank you.

Have you left it on long enough to see if the system starts up? Getting a bois prompt or error message?

The squeal... is that the motherboard speaker? or noise from power supply?

If it's the motherboard, then you probably have something loose on it... loose ram, or the video card you just put on... try and refix all your components... (totally remove them, then refit)...

If still motherboard beeping... maybe video card is bad? Got another card to try?

Does this help?

Would you please post the make and model of this computer?

If this is a custom built computer please post the make and model of the motherboard, the graphics card, and the PSU.

Let is run for a little bit and see if you can determine where the noise is coming from, and see if the computer boots up.

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

I just bought a Dell 540 Studio (not slim) and I find that it only has a 350W PSU. Can I put the PSU from my old computer in there? it's 700W and has the PCI-E connector I need
to hook up my ATI 4850 512MB video card. Would putting in a new PSU hurt my main baord?

Measure carefully
Height and width are standard
Length can vary and sometimes be a problem

Who's power supply! Dell power supplies use a different wiring sequence then the rest of the world, if by chance you bought another brand you need a http://www.atxpowersupplies.com/Dell-P10-c...tor-adapter.php

If you fired up another brand hooked to the Dell board you may have damaged it.
