Something mighty weird is going on. As I posted earlier my mobo "died" about a month ago after repasting my CPU. It just refused to switch on. Tried it with other psu's etc. and repair shop said sorry - dead. I was content with that (after all - old mobo Asus A7V kt133). Then while waiting to purchase new one a7N8X DELUXE, brought in old gigabyte temporarily. That did not swich on either. Took it to repair shop - it worked fine. Took it back, worked again (not at my home). Then wondered whether other dead mobo might work and funnily enough it did. Bought new psu. Back home. Mount on panel. Works in vertical position, not in horizontal (no video signal, powers fans). Then after 3 hours of playing with it - back to it's normal non-powering self. Back to work. Everything works fine- horizontal, vertical, all psu etc. (Of course I tried on panel, off panel) I can't explain this guys and I'm plain fed up with it.
