I have a Sony Vaio laptop, running Windows Vista. It started freezing a couple of weeks ago but after a hard reboot it would work just fine. During the weekend it started freezing more often so I decided to check basic things that I know how to do. I ran
chkdsk, defragmented the Hard Drive, ran the Vista Memory Diagnostic tool, and all the Vaio checks (CPU, memory, disk, monitor, etc). Everything turns out OK except some errors on
chkdsk that were fixed.
I continued to use the computer normally and when it froze again, it wouldn't reboot. When I try to boot Windows normally, the computer is stuck on the loading Windows screen. When I try to use the Vista startup repair, it doesn't recognize the hard disk, so I cannot enter it.
I tried booting in safe mode but it stops at
crcdisk.sys. I tried using the Vaio tool to format and reinstall everything but it does not load either. I even tried using an Ubuntu live CD that I had and when it starts loading it also freezes, so I'm thinking that it's a hardware issue but I'm not sure. If it is a hard drive hardware issue I can change it myself but before buying a new one I want to make sure that is really the issue.
