I will have to wait to go to a friends house to replace the PSU.
But i have one other thing that i realized , the PSU is making a very high pitch noise. It doesn't stop unless i completely remove power from the computer.
I googled the high pitch noise and got "Coil whine" , is this a sign that it is infact my PSU?
other thing i have done. I re-sat all cords , ram , gfx card.
I tried starting the pc with no ram inserted but it didnt make any noise.
