Right, so I have an omen 880 and I have done a couple upgrades over the two years I had it. I wanted to upgrade the case so I chose a Corsair 280x and began moving it in. Just before moving it I used it and it was all working fine. After moving it it now no longer shows any kind of life, no fan spin no nothing. The only thing is a small noise coming from the new power supply the Corsair 850x. I have tried re seating the cpu, the motherboard standoffs, using one stick of ram, using the old power supply to power it but still nothing. One thing to note is the power button which was different, but I have tried removing the power button from the old case to no avail. I am out of ideas and really need help.
