This week I got a shock when my PC, that has been running perfectly for over a year, suddenly broke.
The screen went black. It's definitely not a monitor fault or DVI cable issue as I tried alternatives and issue still remained.
Below are the specifications of the PC:

I made no changes to the hardware in over 6 months (then it was just installing the SSD). However I did recently move the PC to another location. A few days after the move the video signal from my GPU failed to reach the monitor. I thought something may have become loose durng the transit so I opened the case and ensured all connections were secure. Still no luck.
When I turn on the PC it sounds just like it did when it worked fine i.e. no beeps & I can hear the fans and the mechanical harddrive. However I don't see the fan on the GPU moving at all despite the light on the GPU indicating that it is receiving power. I even tried two other GPU's this week but neither were sucessful. I heard RAM placement may be an issue so I tried powering on the PC with only one RAM stick at a time. Still no display.
Now I'm really not sure what to do? Are there more steps I can take to determine the fault? At first I thought it would be a faulty GPU but now I think motherboard may be more likely?
Any suggestions in this case would be greatly appreciated.
