My computer is a Toshiba Laptop L755 running on Windows 7.
Aside from major lag when playing videos and running basic programs such as mozilla firefox or MS office, on BitTorrent, i have been receiving a few "cyclic redundancy errors" in the past few months and this week, the majority of my downloads have had that same error.
I downloaded and ran Seatools and it failed both the "Long generic" and "Short Generic" test.
I have formatted the computer several times in the past year and the same lags have occured. I even fully formatted my computer (deleting all backups of my preinstalled applications including windows) and the same lag occured. So I feel this is a hard drive problem.
I am hoping this is a hard drive problem that can be fixed with a software. Thanks!
