Orange Light on Motherboard and 2 Beeps.

[Jaly18]

So, I got a new PC given by my friend, and I don't know what the hell is the moherboard. When I plug it in the Power Bar, a Orange Light on the Motherboard appeared, and when I clicked the power button the fan started spinning, then stops, then start again, then gives me 2 beeps, which means no memory detected. so, I tried opening it with one stick, won't work. and then the other one, won't work aswell.

Specs:
Unknown DDR2 LGA775 Motherboard
Intel Core 2 Quad Q8400 2.66ghz
3 Gbs Ram
AMD HD 5450

Sorry for my bad english. Thanks

EDIT: The Orange light is near the 24 pin

beepo could also be no video sorry but not every single boards beeps or blinks the same colored lights .

try this reseat ram video cards if applicable.

then if still don't boot pull cmos battery or clear the cmos loom for 3 pined cmos pins close to where ya plug in the towers powers switchs and stuff to the main board it will say cmos next to the 3 opins move the cmos jumperfrom one side of the 3 pins to the other after 1o secs replace to default position can also check the board for other writing brand model ect on it ussaly always printed somewhere on the board unless its a pc manufactured by a company like dell hp Compaq systemmax emachines Lenovo gateway ect...

more then likely just need to clear the cmos and pull the cmos battery gfor 5 to 15 min . ussally don't need to pull the battery that long but there have ben cases on systems ive worked on it take that long for power to comp-lately discharge fromt he system.

also be sure to always disconnect power and discharge system and hold in the power plug for 10 secs or so before ya ever reseat ram video or internals unless ya got hot swap ssd and sata drives.
