So had it set up and working for some time. Then I decided to make a new PC, and take some parts from it - the HDs and PSU and make a new system. Well i ordered a hd and a psu for it to have two systems. It was working fine but i think the hooks for the ram slots might have come loose. I know if you are using two memory sticks they have to be dual channeled. I put two memory sticks one in a1 and one in b1 and get no post at all. I put one stick in b1 which is what you do if u are using a solo stick - no dual channel and it works fine. The ram appears to be fully in its slow and doesnt seem to feel loose. I am not sure what the problem might be. I got the manual and can upload it somewhere if needed. (its over 7mb)

Well I have tested the Ram and the video card in another system and they both worked fine.I really assume the CPU is fine too.
