Guys somethings happend:
Problem started last night when I tried to turn on my pc and nothing happened but the mb lights were still on. I switched it of at the wall then back on again and it worked fine.
However today same problem happend were it wouldn't turn on (mb lights still on) turned it off at the wall back on again and as soon as I did I saw a spark from inside the PSU.
I then switched everything off and unplugged it all, but I'm not sure what the plan if from here?
