PC not turning on after installing sabertooth 990fx

post #1 of 9
Thread Starter 
OK, so I replaced my previous motherboard with a sabertooth 990fx and bought a fractal desig core 3000 USB 3.0 case, but after moving all my hardware over to the new mobo, my PC is not starting. I don't even get a beep or anything. I can see that the m,otherboard is getting powered, but that's it, so what do I troubleshoot first?

-Is it plugged in, power, monitor.
-check all the connectors
-have you the standoffs in for the new motherboard - grounding issue.

Monitors are plugged in, MBstands are all in use, and the green light on the mobo turns on, when I turn on my power supply, but when I hit the power button.... a big nothing

What are your thoughts on connectors? I've set it up to the best of my knowledge with pwrswitch, PLED, HDLED, reset, and everything.

Double check the config for the power connector on the mobo, check the manual. Also try taking out/re-seating the ram.

If that does not work I would take the mobo out of the case, put on a non conductive surface, ie wooden table and see if you can get into the bios. Disconnect all other hardware.

If there is power going to the mobo though, it sounds like an issue with the power on switch itself.

Don't think so, try the button from old case

If there was a problem with ram/cpu or gpu etc there are red lights on that board that indicate the issue
power to the board green light shows up when psu is providing power

You should be able to short the power switch pins with a screwdriver to test board power on
if the powerbutton on the case is stuck /shorted the board won't power up
