Sorry the delay m8 but been away.
Downloaded the manual and some interesting stuff.
Do you have the D-Bracket that comes with the MB. This has 4 led's on it that tell you whta is going on with the system.
Also on the memory front, taken from the manual:
User may install mem modules of differrent type and density on
different channel DDR DIMM's. However, the same size, type &
density memory modules are necessary while using dual channel
DDR, or instability may happen.
This point alone, as you have 4 modules then you are in Dual Channel mode and will have problems. Not saying this is the issue but unless you do what is required then you will have problems. So try system with 2 identical mem modules.
Looking into the Geforce 7300LE at the mo to see if there are problems there. But as you said if it posted and the display was up then I doubt if it's the graphics card.
