plz help!

Was it a standard heatsink fan that plugs into the M/B itself, or one with a sensing wire with a separate main power adapter, some of the latter setups have to have the Fan Off Control feature deactivated in the CMOS setup, or the safety feature shuts down the M/B, now thats common to newer M/Bs and you didn't post what you have.

No beeps, nothing on the screen, HD's led or CD-ROM activity?

Do you have another CPU to test it? I just hope you didn't hurt the CPU core when you change the HSF ...

shuffle the RAM about. try different slots for each stick of RAM

Isnt that the board that runs unstable with anything less than a 350 watt PSU, if so the new fan could draw a teensy bit more than the old one, making it extremmely unstable.... ok bad idea. But what PSU do you have anyway?

My sig's faster than yours, and it overclocks better too....

If I'm not wrong, the CPU will warm even if it's broken. Happen to me with one broken EDO RAM (yeah, old times). I think the reason it's because the mobo still supply power to the CPU. Even the CPU can't do its job, it's consuming the energy (don't know if I have explained quite clear ...)

I you have already try to hook to your PSU the basic components and still doesn't boot, maybe it's time to quit your HSF and look carefully to your CPU core. Look for scratches, specially on the edges and corners. If it's perfect, try to get an AMD CPU from a friend just to make sure it isn't your CPU.

Hope this helps.
