I don't see the brand and model of hard drive, nor the build date... But looks as if you may need a new hard drive or possibly a motherboard as that model of Toshiba has had more than its share of problems.
I would start by saving all your data, download all the drivers, then feformat and reinstall the hard drive... and cross your gingers.
It might be a bad time to replace the hard drive, since prices are high, but if you do, then save the old one as is to save all the data. Or you can put the drive into an externa enclosure and save everything to a desktop burn to a DVD.
