Still try upgrading to the latest BIOS. What are the rest of your system specifications?
It was brought as a complete system not built by me - Mesh Elite .
CPU I think its an Intel E6400 core duo running at around 2.13ghtz,
4GB DDR memory installed.
O/S Windows Vista 32bit
Nvidia GEforce 7600 GS
its a socket 775 - most of the on board chips are Nvidia I think.
I'm not too hot on the techie side
