Remove the CMOS battery from the motherboard(while the system is powered down and disconnected from the wall) and then replace the battery after 15 minutes. Also, if I were you, I'd have gotten a 550W PSU that was made by the likes of Seasonic or at the very least a higher wattage unit made by Be Quiet!

I notice fans were on and lights too. I did what u said and now im waitibg. I used a PSU calculator and it said my System was going to consume only 323 Watts so i went for the 400 PSU. The computer its going to be for my girlfriend and all she is going to be doing is office work and playing SIMS 4 so thats why wanted to do some undervolting so that the PC is quiet and cold. U think i need more then 400 Watts PSU?
