Hello everyone, thank you in advance for any help!
I home built my brother a computer almost 1 1/2 years ago and have replaced the motherboard (Asus P5Q Deluxe) three times (third one works while turned on) and the power supply once (Corsair 520HX to the 620HX), my YouTube video shows the problem with shutting off. The first two motherboards the whole computer would not post, the third motherboard works flawlessly while using the computer, but ALL of the fans either stayed on never turning off or surged on-off-on-off over and over until I pushed the switch on the back of the PSU. Why am I having the same issue with three motherboards and two different PSU models? I will list the specs of the computer below, note that I have tried the EVGA 9600GT, G.Skill DDR2 2x1GB, Western Digital HDD in my computer which works flawlessly! The only thing I have not tried in my computer is his P5Q Deluxe mobo, Corsair 520HX and the 620HX PSU. I'm hoping it's just a BIOS setting, I really am! I have also assembled the motherboard outside the PC case with the same problem!
