LOL, Since i'm using a laptop now my monitor wouldn't show anything so I tested the monitor on my bros pc, (means I had to unplugg the power of my monitor and move it the he's pc) then it worked, and I took it back to my pc and I came in, well yes 2 of my ram sticks is not working, but its working with my 1 stick, 2gb
my problem actually was my monitor was bugged somehow :S
