While the pc is running it suddenly turn off by itself and it gives me a red light on the psu, and this happens frequently sometimes after hours of running normally and other times after minutes, and i cant figure out the reason for this.
Specs are :
Asus x99 deluxe 3.1
Psu corsair 1200
Msi gtx 1080
16gx2 ram
Corsair110i cooler

In order to turn the pc again i have to unplug it and then replug it again.and when it starts again it goes to bios mode not windows..
I need help resolving this issue

Assuming you've reseated all cables and RAM modules to no effect (with power completely removed of course), the logical first step would be to replace the PSU with a known good one of sufficient wattage, and see if stability is re-established... (Given the very intermittent nature of partial shorts and the difficult nature of detecting them, you might want to even test for improved stability with everything unnecessary disconnected from using power and connections to motherboard, i.e., disconnect unneeded secondary storage drives, including both power and SATA, disconnect un-needed USB ports, even any fancy USB-powered/controlled LED contraptions. Any partial short can stop nearly any PSU in it's tracks...

If freezes/reboots continue...

If freezes/reboots continue, you can usually logically assume the disconnected devices most likely played no role in the freezes/reboots (well, barring multiple failures, anyway)
