Hello, I'm in a bit of a pickle at the moment and I need a little help, I just got a Lenovo Thinkcentre M900 motherboard.


When I plugged it in the wall I got no display, no keyboard or mouse reading, the USB's turn on, but the CPU is cold and the fan is really weak, the hard drive does get a little warm but hardly at all, I've tried getting a new PSU since my CPU is a Non-T processor thinking that the 90W PSU wasn't enough, but that didn't work, I tried hard resetting it, unplugging it, holding the button down only while the lights are on for a harder reset..... But nothing.


I know the CPU still works because the CPU paste was spread out on the thermal like it normally it should.
