I just bought this board and a compatible CPU, and I also cannot boot, though I do have fan and LED power.
My power supply does have the 2x2 connector for the CPU, but it has only a 10x2 main connector, not the 12x2. The user manual says the board's 12x2 socket is backwards-compatible, but I wonder if that's true.
I've removed everything else from the machine now, read through the manual, and triple-checked all the connections. Do you think I need to get a replacement power supply with a 12x2 connector.

Re: Followup on power connectors
Hi chweb1230, to answer you're question. Yes, I would suggest getting a power supply that would comply with the ATX main 24-pin power connector. The term backwards compatible references to boards that require less voltage, Ex; (A 20-pin main power board). If you intend to run serial ATA SATA drives & a PCI-E graphic card. The newer power supply will handle future upgrades. Suggest a 500 to 550W PSU should handle just about anything you add to the board. chweb1230, when you make a post & are making reference from another post.

I have 3 of these boards; however, they all have the Nocona Xeon with a Front Side Bus speed of 800MHz. The manual does not say anything about using a 533fsb. A second thought was if your power supply is an ATX with a 24 pin power connector and two +12 connectors one 8 pin and one 4 pin? The manual states all three need to be connected for the Xeon Processor.
the things youre describing that are not controlled by the same power connectors. the 1st set that works are powered i think by the main large rectangular power connector. the stuff that's not working require more power connections. the cpu fan has a small wire that connects to a small connector on the motherboard right near the cpu. the optical drive connects to one of the the 4 pin power connectors coming from the power supply, same with the hard drive- same power connector. the front usb light is going to connect to a specific tiny 2 pin connector on the mobo, it will be labeled with tiny white letters-- try to find or download the manual. godo luck!
This could be several issues. You need to be much more specific on exactly what you done and what you installed. No video boot could be the following:
1)Memory clock speed not compatible- Say board only see clock speeds of 200,266,333mhz but you installed 400mhz CL or the bios is not set to auto mem cl speed and you need to manually change mem clock speed.
2)Your CPU, memory, or video card not fully inserted
3)Memory module of video no good if it has onboard mem cells
4)You forgot to plug in the yellow/black CPU connector on the board sending no power to the cpu
5)CPU pin bent on install or not seated correctly
I could go on and on but there are a few issues that cause no video boot so double check all you cards and connections.
I know you say you have the cpu fan connected and assume you have the front panel power switch and restart cables etc.. connected, but have you connected the processor power supply lead from your PSU to the board as Sempron have a seperate power lead to the board to power it up, unlike the old Athlon processors.
If you bought the CPU, Heatsink and fan together then it will already have thermal paste on the Heatsink, so don't apply any more.
Hope this helps, as I don't wish to teach you how to suck eggs!
