MacBook won't recognize HD after crash?

I was browsing one day and my laptop froze; cursor, keyboard and everything. I used the power button to turn it off since it was the only thing I could do and was greeted by a flashing folder icon once I powered it on.

I used internet recovery to reinstall the OS and can now boot it up and perform normal tasks, but it will randomly freeze again and I have to shut it off, which I get the flashing folder icon upon reboot. I found that if I wait about 10 minutes after it all crashes, I can reboot normally, but it’ll inevitably happen again. More often after a download or watching a YouTube video.

I’ve tried First Aid with Disk Utility, but both it and DiskWarrior said there was nothing wrong with it. Same with doing a hardware test. Though, after the reinstall of the OS, DiskWarrior stopped recognizing my HD, saying “no disks available.” So I’m stumped on what the problem could be.
