This is the 3rd time I build a pc but the first time I encounter this problem. The computer has power, that is to say that the leds work, fans on the case AND the CPU fan both work. The fans on the Graphics card (1060 6gb) start and stop spinning but alot of posts indicated that those fans only spin when the GPX card is being used.
The Problem Lies in that there is no display, AND the USB does not provide power. I know this because neither the mouse nor the keyboard light up when connected even though the case and cpu fans
recieve power.

**THERE IS A WHITE LIGHT ON IN THE MOTHERBOARD UNDER THE EX Debug LED (CPU)
According to the manuel, it says “indicates CPU is not detected or fail.


Here is the build
Rosewill ATX Midtower
MSI 270A Pro
Intel I7 7700
EVGA GTX 1060 GB
Corsair Vengeance 16GB (8x2)
SAMSUNG 960 EVO 250GB
EVGA PSU 500W

I have tried reconnecting everything 3x. Im sure power is connected using both the 24 PIN ATX and 8pin CPU. I’ve tried building it on a nonconductive surface and same problem of power but CPU Led on. I’ve gone through the popular 31 step solution to no avail. Help?

Yes, you can use 6700 to test your motherboard. If it won't work, you would know for sure there's something wrong with motherboard - but that does not mean CPU is good, as it can be that both mobo and CPU are not good. Note that you possibly could test 7700 in your other PC, but I assume it has 6th gen motherboard, so you would need to update its BIOS first to even recognize that 7700.

Thanks for Answering!
So when i go home and try this. If I get the same response, how would I know if the problem is in the CPU vs MOBO? My other PC has an I5 6700, do you think i should try using this instead of my I7. And if it then does not start up would it be safe to assume the problem lies in the MOBO?
