No display whatsoever

[shantanu]

I built this config for a friend 3 years ago

don't remember the specifications but it is a i3 and a intel motherboard - cheapest versions of the time

 

it has 2 x 2 GB RAM modules

one of those RAM's stopped working for some reason

the system was running a bit slow on the 2 GB RAM

so I got a 4 GB RAM now that I install that RAM I do not get the display

what's weird is that now if I only have the old 2 GB RAM installed I do not get the display

 

When the power on the system

The CPU Fan keeps spinning at full speed probably

and when i try to shut-down the system by pressing the power button it does not work

I even tried pressing the power button for 5 - 10 secs, but that does not work either

 

I am out of ideas as to what could be the problem

Someone please help me out

 

Thank You.

Maybe the new ram you got is DOA? Try removing the new one and see if it works.

I tried both the old and new RAM individually in another machine both of them work perfect in that machine. 

 

I tried either of the rams in the DIMM 1 slot/ I tired both of them in either or DIMM 1 & 2 slots/ I tried the DIMM 2 slot

For a few minutes the system booted normally with both the RAMS in the motherboard, that was very odd, and then it stopped .

I checked the PSU by shorting the 4th and 5th pin. that works OK.

I removed the pins that connect the cabinet power button to the motherboard

and started the system directly by shorting the two pins

the system starts, but does not stop if i keep the pins connected for 5 secs.

I do not know how to check if a mother board is faulty or not, so that's going to be a hassle.
