Hi there people Needing your help desperately here. I'm in the UK - I recently moved from London to Brighton. Mac Pro working fine before I left. Now, if I have say Lightroom open, & the browser, the fan freaks out, revs high; the little coloured wheel starts spinning; it jams. I am unable to force quit anything - it won't let me. The monitor also dips to black, & has horizontal stripes running through it. My friend says it is a power issue. Unfortunately he is not close by to investigate further. What do you guys think. Previously I was able to have Premierpro lightroom, multiple browsers, spotify open.. all at once no problem. Is there some kind of adapter perhaps that I might be able to purchase? The building I am now in is an old commercial building with multiple power sockets. Please help!
