PC doesn't boot; fans revving
My friend has a computer he built. It was working fine until recently since he's having this problem where the computer won't boot. I had a look at it today:
Specs of this machine:
Motherboard: Asrock z87-M8
CPU: i5 4690
GPU: GTX 1070
PSU: 450W
RAM: 16 GB
*Drives*
When you turn it on-
>No picture
>Fans start, but are revving (they speed up then slow down repetitively)
>No beep code (this motherboard doesn't have a speaker on it and doesn't have a place to plug one in)
Things we've already tried-
>Trying with just one RAM stick (in either DIMM slot)
>Disconnecting the 1070
>Clear CMOS
>Trying starting with just CPU, RAM, Power (bare bones)
*With all we've tried, the problem persists
Things we haven't tried:
>Testing with a different power supply
>Reseating the CPU
I didn't build this computer and I spent only one hour with it today. I'm wondering if there's something I might be missing.
If anyone has any suggestions on what might be wrong, it would be appreciated.
