Can't boot, hard drive not recognized in BIOS [Windows 10]

[Christiano39]

I've had this same build for almost 4 years now, and today while I was booting it up, it suddenly stopped recognizing the hard drive. I opened the case and checked that the connections were secure, but still no luck. Any suggestions?

Check the hard disk in another port and/or system (also try another SATA cable). If it isn't detected, then buy a new one.
