CPU problems

Hi,

I just got an Asus A7V8X motherboard with 256 MB PC2700 Corsair memory, and an AMD Athlon 2400+ CPU. I'm using a PC Power and Cooling 300W power supply. I've been having problems getting the setup to work, and I think it's because of the CPU. I think the CPU might have burned out when I tried to turn on the system, because every time I try and get it to work, all I get is a burning smell from the CPU. I've tried swapping out just about every single part, and got a new CPU, but I think I might have burned out that one too. Any ideas as to what I'm doing wrong? Replacing CPU's is getting rather expensive here.

A 300 watt power supply isn't really adequate to run a high speed AMD XP CPU... especially if you're using a high end video card, like a GF4 Ti or some of ATI's better cards.
But if your CPU's keep burning up, I'd try a different motherboard... and you really should have a 350 watt power supply that's approved by AMD.
By the way, are you installing the heatsink/fan properly? Using a good thermal compound like AS3?
 
I'm pretty sure I'm installing the heat sink correctly... I'm using the stuff that came with the heat sink from PC Power and Cooling, in about a dime-and-a-half size gob where the sink meets the CPU. That sound good enough?

Is there any beeping or other indicators?

I doubt that you burned up the CPU as your Mobo has ASUS C.O.P (CPU Overheating Protection)

ASUS C.O.P (CPU Overheating Protection) is a hardware protection circuit that automatically shuts down the system power before temperatures go high enough to permanently damage your CPU.

I have fired one of these up 5 or 6 times without a Heat sink at all and the CPU survived. It makes a long beeping sound for abou 15 seconds and automatically shuts the system down. Make sure that the fan is Connected to the #1 connector and not a Cassis connector.
 
You're putting WAY too much thermal compound on it... you only need a VERY thin coating... just enough to cover the core of the CPU... none of it should be oozing out and onto the substrate of the CPU.
