MSI DKA790GX MOBO

By ulvde ·
I built computer recently on MSI DKA790GX mobo, Thermaltake M9 Case, Thermaltake 470W PSU, AMD Phenom X3 8650 CPU, and so on. Connected 24 pin ATX power and 4 pin CPU power cables to mobi, as well as front connectors. But when I push power button comp powers up for a sec and then goes off instantly. What might cause that?

Poor assembly, Incorrectly fitting Parts, a Short Circuit.

Start off by removing the M'Board from the case and lay it on some Clean White Paper. Then connect the Power Supply and front panel leads and try turning on now. If the M'Board POSTs the CPU, RAM and so on are correctly fitted but if it doesn't then you need to look at the orientation of the CPU in it's socket, the way that the RAM is fitted to the M'Board and if the Video Card is correctly seated in it's socket.

If every thing is correctly fitted and the system still will not POST the M'Board, CPU are the most likely culprits followed by the RAM and Video Card as being less likely.

If the System now Posts there is a short Circuit in the case so look at the Stand Offs that the M'Board Mount on and make sure that every one is under a hole in the M'Board.
