memory or motherboard problem

[Guest jaydk]

when i turn on my computer, the first diagnostic led turns off which indicates that ram are not detected ok.. i have tried with different cpu's, same result, and with different memory modules.. this indicates that the problem is located on the motherboard right?

Hello,

 

The memory must always be in the orange slots.

And make sure that all 4 power connectors are plugged into the board.

 

Clear the CMOS for a few mins and see what happens.

 

If it is still the same, remove your gfx card and power the pc.

Does it do anything different?

[Guest jaydk]

same story

[Sharp]

CMOS left in the clear position for 10mins?

Definitely sure about the 4 power connectors?

 

3 LEDs lit = CPU detected

 

Last thing to try, 1 memory stick in the top orange slot.

CMOS left in clear for 10 : TRIED

4 power connectors unplugged and replugged in : TRIED

one memory stick on top orange slot : TRIED

 

same story as before. 3 LEDS lit, no picture on monitor

 

that does mean CPU detected, checking RAM, right ?

[Sharp]

Yeah its trying to check the memory.

 

The memory controller is inside the CPU.

 

You said you have tried 2 CPUs, RMA the board.

Had the same problem with my EXPERT recently. Had to be a board problem.

 

Tried the RAMs and CPU on another board, boots up fine.

i tried to CPU, just because i knew the memory controller is located inside the CPU
