Hello,

I have just put together a new pc, with an i5-4570, 16gb corsair vengeance lp ram, a 1 tb hdd and an h87 mobo. It is running on an antec truepower trio 430watt psu. Why doesn't it work? It will start up, but there is no post, and it doesn't keep restarting. I can turn it off via the powerswitch, etc... I tried the ram, but that makes no difference. I need to fix it for my sister's birthday tomorrow! Please help!!!
