Help pc freezed while gaming and now prompts me too select proper boot device

[luizluz]

Yesterday i was playing overwatch, when suddenly the pc freezed and i wasn't able too press cntrl +alt+del, só i forced the shutdown. Then when i restarted i was prompted to select de proper boot device. I've already check de boot priorities but they are correctly, both drives are recognized in bios but don't boot. I also tried changing the sata ports, connecting and disconnecting every connection( Ram, CPU, GPU, drives), changed the boot from legacy to UEFI.
What could be?
Ps: sorry for the bad english ; )

My specs:
Cpu: i7 7740x
GPU: gigabyte 1050ti
Psu: evga 550w 80+ gold
Mobo: msi x299 sli plus
Storage: ssd kingston a400 240 gb
Wd caviar blue 7200 RPM 1 tb
Ram: kingston 4gb 2400mhz
crucial ballistix sport 4 gb 2133mhz

Do you have a spare drive to test with? Take the preexisting drives out of the build, then install windows on the test drive to see if it will boot.

You can purchase a hard drive usb adapter to back up your data. You may have to format/reload windows.
