Hi, ive found out two things. I have 4 RAM slots, 2 of which are in use. The slots are coloured (i dont know if this makes any difference or not), and the RAM is placed in the 2 green slots. When i put one of the RAM pieces back in the slots, if i use the left one (see the picture) it beeps at me and wont boot at all. if i use the right hand green one it boots fine, however the screen still goes black.

Secondly i had a programmed that was supplied by ATI called AMD Fusion, it is meant to overclock the pc and graphics card automatically so you dont need to mess around with clock speeds yourself etc. I removed it a while ago as i never noticed much difference but it has started coming up with this message when i start my pc. Not sure if this could have any effect.

I really appreciate your help on this. Thanks.
