So, I've bought a 'new' desktop computer. Its an oldie with a P4 3Ghz CPU on an MS-6577 motherboard. Why oh why then does it only do 1.5 Ghz? So far I've tried:
1) Fiddling with BIOS
2) Resetting CMOS
3) trying to find a new BIOS
4) New fan and heatsink
5) Different CPU (that doesn't even work: The new CPU's don't seem to let the damn machine boot!)
6) Different RAM
The last thing I can think of is that the power pack doesn't have enough oomph to run the CPU to full speed with a graphics card attached, even though its only an AGP...
