My system has been working fine for awhile but recently it is experiencing an annoying start-up problem.
Gigabyte GA-890FXA-UD5, Phenom X6 1055T, 8 Gigs RAM GSkill, XFX HD5770, 1000W Sparkle power supply
Initial power on results in power to the fans, lights, even what sounds like the hard drives, but no POST and no power to monitor, keyboard, or mouse.
I power off the system (via holding button for 4 seconds). I power on the system again and then it will POST and boot up normal. This is now a consistent routine.
Any suggestions.
