Ok, guys, gals, animals, sharks, fishes, vegetables, animals, minerals, etc.
Here's one for you.

I just replaced the motherboard, CPU, and power supply in my new machine.

Motherboard: Asus M3N78 Pro w/ GeForce 8300
CPU AMD Phenom 9850 Black Edition
Power supply: Thermaltake W0116RU 750W

I'm not getting anything. I hit the power switch, the fans twitch, but that's it. Memory is known good and approved for the board. Video is onboard GeForce. Tried PCI video card instead, no luck. Tried the memory one stick at a time, no luck. Tried nothing but onboard video and one stick of ram, and the boot drive,
no good. There are no jumpers on this board except clear CMOS and chassis
intrusion.

Unlikely to be memory - because even without memory the pc should start, although it won't get very far before the bios beeps at you.

I'd suspect the m/b or power supply. Since you said this is a replacement, are your old m/b and power supply still available? (and do they work?) If so then use those to identify which are good. Be aware that if the power supply is duff then its possible its fried your motherboard, so don't try placing the suspect power supply in a working system. However, does the pc start with your old power supply? If it does then clearly your new power supply is bad, if it doesn't then your new motherboard (or cpu) is duff - but this doesn't put your new power supply in the clear because it might be what caused it to die.

Other possibilities, have you got all the necessary connectors between the power supply and the m/b connected? I'm sure you have (because your other replies indicate you know what you are doing), but just incase ... normally there is both a 20 pin connector AND a 4 pin connector to connect, which may be together (i.e. a single 24pin) or separate (20pin and 4pin).

The only parts *not* known to work are the new ones, and I don't have the time
or inclination to mess with it. Any ideas on what I should RMA out first?

Sorry, I think you ought to narrow it down a bit before you start returning parts.

Hope you get it sorted.
