Check all power connections (including aux +12V power) and make sure you have everything plugged-in. A quick check at Intel shows the mobo/cpu combo are compatible. Strip it down to the bare basics and go from there. Confirm your memory configuration and reseat all DIMMs. Confirm all connections are good and make sure to use the primary video PCIe port (closest to the CPU). If you haven't already done it; download the product manual too. The board accepts to 8GB of RAM if I remember right so using single sticks of 2GB should be supported. See product manual for memory population rules.<BR>

If all connections are good according to manual and configuration is per mfgr., then I'd say you may have a dead board. Just make sure you have all power connections made to the mobo...that is key.<BR>

A friend gave me a new Intel DP45SG motherboard and a Q9550 Core 2 Quad processor
so I bought what I thought would be a good set of DIMMs to go with it. The DIMMs
are quantity 2 of DDR3 1333MHz 4GB. So I put it together in a new case and a 430W
power supply. The system will turn on but I get no video. Looking over on-line docs
for the motherboard I decided perhaps the 4GB DIMMs were not suited for the mother
board so I purchased some 2GB DDR3 1333MHz DIMMs instead with high hopes that this
would solve the no video problem. No such luck. The motherboard has an on-board
mini speaker which I believe is where any post beep codes should come out. I am
getting nothing from that speaker so I decided to try hooking a regular external
speaker up to the standard audio ports to see if I was getting anything there.
Nada, nothing, zilch.
I tried two different video cards that work in other systems fine but I still get
no video out when I power on this system.
In looking over the specs for the q9550 processor I see it is supposed to have
a 1333MHz FSB and the motherboard definitely lists support for DDR3 1333MHz memory.
Anyone here have any ideas or suggestions?
