About two weeks ago, I went to boot my computer (Windows 8.1), and got a blue screen saying there was an error booting windows. After hours of trying to get it to any kind of boot menu, I was finally able to get some boot options. I tried running the computer in safe mode, but when I did, it said there was no operating system detected. The first thing I did when that happened was to try a new SATA cable with my hard drive, but that didn't help anything.
After that, I tried running chkdsk, which detected more than a couple bad sectors, so I ran chkdsk /f /r /x. I let that run all day, but even after around 10 hours, it still said it wouldn't be done for over 999 hours. I felt I had no choice but to format and reinstall Windows.
It worked. Or so I thought.
The computer was running a little slow, but I got the programs I need downloaded again, but when I tried to use one of them (Camtasia), the program crashed almost immediately. Even though I got the program closed, the rest of the computer crashed shortly after, and rebooted itself.
I'm not hearing any kind of grinding, but there has been some extra heat coming from my hard drive since this problem started. Is there anything else that could be causing this problem, or is my hard drive failing, like I fear?
