Loud squealing

Ok, need some input....i've got this loud squealing coming from the pc....thought it was a fan, replaced ALL of the fans. Still did it. Thought it was the power supply, replaced it. Still did it. I was getting memory errors and the system would hang with the memory even running in turbo mode in the bios..... had to keep all settings to stock values. Is it possible that it's a capacitor on the motherboard that powers the memory slots? I can't seem to track down WHERE the noise is coming from in my tower.
 
P4P800's have been known to have caps go bad on them, are any of yours bulging on top? Sounds like an inductor is squealing from a vrm somewhere, you could try touching/prodding some of the large inductors individually to see if the sound changes.
 
they don't appear to be bulging at all......and it hasn't done it now in a few days. Kinda sucks because it's actually my main machine that I use for web surfing and my banking. The newer machine that I have in my sig I don't use much except for gaming and music in the office, I don't let anyone else touch it! LOL! I'm gonna have to decide what to do now because I really wasn't wanting to build another PC right now, and the hardware in this thing is great for the surfing/banking/minimal use we give it. So finding a 478 socket board with AGP 8x to use the card I've got is gonna be a quest. Any ideas anyone? For minimal investment!
 
Sounds like an inductor problem. The squealing is caused by the inductor coils. Could be from the motherboard or the video card.
 
I've heard often of people talking about bulging capacitors, but never actually witnessed this..will they bulge at the tops and have a kind of dome on them that I can distinguish....or all around. Really I just want to know if I'm gonna KNOW what I'm looking at.
I found a cheap motherboard on the egg, that I can use the AGP card in still and only have to buy another processor....I think I can get both for under $200 and still have a decent general use pc. Now if the video card is the problem....then I should probably be picking a better board out...I'm just gonna have to keep this CHEAP if I have to do anything. Thanks guys.

Why not just install the P4 in the Asrock motherboard and save $120 (since you mentioned it's a minimal use PC)?

Edit - n/m, saw you have a socket 478. sorry!

Some examples: http://en.wikipedia.org/wiki/Capacitor_plague
It can range anywhere from a slight dome to dryed electrolyte being visible - the bottom seal may fail instead of the top vent in some cases. Some caps can even fail without bulging, but this is far more rare.
