I am building my UIO server with the X7DCU main board and CSE-815TQ-560UB chassis. The motherboard is working fine on the work bench. When I place the motherboard into the CSE-815TQ-560UB chassis and secure the CPU heatsink the system will not bootup and give me 7 short beeps. What could be the issue?
Please take out the X7DCU main board and check all chassis standoffs. If there is an extra standoff by the DIMM area remove it.
