I was running a stability test through Aida 64, when I left it everything was fine and working as I expected, however when I came back to the PC after 20 minutes or so, the elapsed time was quoting, "1193039:08:18". 
At this point I stopped the test to investigate the fault, and here I am now. 
If anyone has any idea on what is going on, would be a great help haha
