I purchased the parts below to build a computer.
After hooking everything up it seems to turn on and stay on but there is no video output.
I have swapped to a different video card with the same result.
I confirmed that I have the 12 pin connector and both 4 pin connectors on the motherboard and on the video card I made sure the power connectors were listed there. The second video card I tried did not require extra power connectors.
I have the ram in channels A1 and A2, leaving B1 and B2 empty.
There is a single power indicator on the motherboard and when connected to power it lights green.
There are no system beeps or anything when it starts up but it doesn't seem to power down or reboot or anything. I took one stick of ram out of A2 and now it gives 3 long beeps when starting up but still no video output.
