Anyone come accross a PC that fails to post and when you turn the psu on with its switch its fans start wirring but that is all? IE, the PSU fan starts going without anything else happening and neither the reset switch nor the start switch produce any effect after this. I've tried with 3 PSU's now and the first 2 just didnt do anything but the third has this weird fan thing going on. Strange because the mobo was fine and all I did was take it out of old case, put it on antistatic bag for a few days and then put it in a diff case. Still useing same cpu, ram etc...
