Hi All,
This is my first home build. I finally got all the pieces yesterday and when I was done, the computer didn't start. Not a hum, nothing. Checked that the cabling was accurate and it seems so, but I'm just not sure if the problem is the PSU or the mobo. I am a student taking classes to become A+ certified, so I'm a bit embarassed. I feel I should know this already. Due to take my A+ in a few weeks. Anyhow, here's what I used:

-MSI 790XT-G45 AM3/AM2+/AM2 AMD 790X ATX AMD Motherboard
-AMD Athlon II X4 635 Propus 2.9GHz Socket AM3 95W Quad-Core Desktop Processor Model
-SPARKLE SFPX94GT1024U2 GeForce 9400 GT 1GB 128-bit DDR2 PCI Express 2.0 x16 HDCP Ready Video Card
-Antec Sonata III 500 Black 0.8mm cold rolled steel ATX Mid Tower Computer Case 500W Power Supply
-G.SKILL 2GB 240-Pin DDR2 SDRAM DDR2 667 (PC2 5300)

The hard drive is one which was purchased only 6 months ago and I already made sure it was compatible with the new system. Since it's my first time, I appreciate all the feedback you can give. I've never troubleshooted power problems before. Thanks everyone!!

Tried the tutorial to no avail. But how do I know which is dead the mobo or the PSU? I don't have another PSU with the required voltage to test the mobo, and no multimeter to check the PSU... I don't think its the CPU, I mean the fans won't even move.

Sorry, must have missed that. Going to try that now. Wish me luck, lol :)

Sorry I didn't answer sooner, I've just been busy. But I did try the techniques to troubleshoot the power supply. It was working properly, so the only logical conclusion is that the motherboard was DOA.

Thanks for all your help ya'll. :)
