Have searched for answers but resorted to posting in hope.
Recently moved house and fear my workstation doesnt like the new place

Power on and the graphics card registers on screen and then the bios logo appears and powers off!
The point of power off is not always the same, sometimes the bios logo doesnt appear.
I have started at the root of the possibilities working from power source to the bios. Have removed memory and cleaned and checked heatsink and fan. I am no bios expert but I think I am right in saying it has been through the power checks and has moved on to loading the bios rom?
Any advice and help greatly appreciated.
