Hello and welcome to Bleepingcomputer.
Your computer make and model number would be helpful to us in offering better assistance.
It appears your system was running fine and then a problem popped up.
The question is why the problem popped up out of no-where.
Was there a power failure or electrical storm during this time?
Was the system used by another person during your absence?
Was there a reboot performed?
What I would suggest is try opening the computer if this is a desktop model and try disconnecting the data cable from the primary hard drive, then re-connecting it again. Data cables connect to both the hard drive and the motherboard, so you should disconnect the cable at both locations.
Your connections could be hindered by oxidation or corrosion on the metal contacts.
This can cause hard drive issues such as yours.
Once this has been done, I suggest you boot up the computer and access the computer's BIOS utility and check the status on the PRIMARY CHANNEL, this would be where your hard drive would be connected.
SATA drives would be SATA 0 SATA 1 etc.
Make sure the drive is recognized by the system in this area.
Once you have performed this task, please post back if your computer continues to do as you posted above and we'll take it from there.
