Updating the microcode for 775

[konkorfour]

Hey guys, bit of an odd question here that I'm sure a few of you must know the answer to.

I recently found an old Dell Compaq Tower that has a LGA 775 MoBo, it has a Pentium 4 inside it but I figured I'd get it up to basic standards for my younger brother to use for Minecraft and such. I updated the bios today as I just purchased a Q660 for it. The machine doesn't even start the fans, it just gives continuous beep errors and a red light.

Searching online it turns out there is a MicroCode update for the LGA 775, it's listed a year before the bios update I ran. So my main question is if a Motherboard doesn't support a certain CPU or doesn't have the right MicroCode to do so, will it not start at all? Or should it be giving Post errors on screen?

Also my second question is if I update the latest BIOS file with the MicroCode.bin I got from Dell would that possibly fix it? Or should the BIOS I got for this specific motherboard have it already since it's newer?

What chipset is it, not all 775 chipsets have the hardware to support the core series of processors.

Checking on Device Manager it's listing Intel(R) 82801G x4 and Intel(R) 945G twice, if this isn't what you mean please let me know how to check. I just checked the latest bios file I updated with and it doesn't include the CPUID of the Q660, the bios worked perfectly though as with the P4 back inside it's running a lot faster.

look like the 945 does not support C2Q. http://ark.intel.com/products/27720#@compatibility
