Hi, I hope somebody can help me with this problem. I'm getting an error code after running diagnostic:

Error code: 2000 0142

Validation: 105819

Msg: Hard drive 0 - S/N S2WZJ90D494088, short self test unsuccessful.

I have a Dell Inspiron 15R 5521 that I bought about three years ago. These past couple of months it had been really slow in general, so I formatted the laptop and started to install software again.

However, after updating windows and installing Office 365, it became slow again, had trouble booting up, and couldn't open any office file because the laptop would freeze. I uninstalled Office 365 and ran disk scan with AVG TuneUp, but it froze at 27% for like 20 hours. I had a hard time booting again since everytime I did it, the disk scan would start and freeze again.

Yesterday things seemed to be back to normal after uninstalling Office 365, but when I ran diagnostic, the 2000 0142 error came up.

I've read that my hard drive is probably messed up :( but the laptop works fine except for office. Is there a way I could fix this without having to buy another hard drive?

Thanks in advance.
