I have an old HP Pavilion m8000n that powers up, but theres no BIOS or display on either the integrated graphics, or the NVIDIA GTS 450 thats plugged.

CPU is a new AMD Athlon 1660(AM2)
Motherboard is a replaced stock board.
8GB of RAM(DDR2)
PSU is a brand new 350watt.

Light on the front of the case is yellow, the blue one never turns on like normal.

Hello,

Well I'd start slow and steady. Take all but 1 stick of ram out, take the graphics card out, unplug the hard drives/dvd drives. Get the machine to a skeleton boot. If nothing shows still, it could be motherboard or cpu. You could also look for the reset CMOS jumper on the motherboard and see if its in the reset position.

Report back with results!

Already stripped it down to one stick on both the new motherboard and the old motherboard, as well as taking out the GPU on both. HDDs/CD drivers werent plugged in, in the first place.
Already cleared the CMOS via the on-board battery.

Still no display.

Can you swap CPUs? If you can swap CPUs then definitely give that go. It will confirm bad board or bad CPU. Although right away I would lean motherboard but you just never know.

Already tried both CPUs on both boards.

So it kind of sounds like the motherboard is toast. If you've tried all this and still not getting a post it could be a bad Chipset. If that is the case your best choice is a new board which for the older AM2 socket is a bit of a waste unless you're really attached to it. You can get an A8 APU and motherboard for a bit more money. It will also give better performance and be much better in the long run.
