Hey guys, so today i was playing computer everything was fine, left the comp on went upstairs to make some food. I come back 45 mins later and my computer is in bios. For some reason it wont launch windows.

It detects my hard drive and ssd , when i manually hit boot drive the screen goes black, i see the white dash mark, then the white mark blinks like at the top then the middle 3 times then it goes right back to bios, what do i do? Restart my comp only goes to bios. I havent had any issues before this for the passed year

Specs
Intel core tm i7 4790k cpu 4.00ghz
16384 mb ddr3
Asus z97
Video card gtx 970

I havent tried anything yet, played around in bios settings, did default went back to what it was, looked for my usb with windows 10 cant find it. My brother has a similiar comp, should i hook up my hard drive to his comp and see if they work? Is it possible my power supply dieing? Or i got a virus or something? It had to be something with my hdd im thinking but no idea how to fix this, also i just got a new ssd hdd and power supply 4 months ago
