I'm trying to check my hard drives health, but every time I open an app to do so, I get a complete system freeze. I've tried using HDD Life and seatools, but have had no luck with either. Same problem with both. It requires me to switch off the computer using the switch on the power supply - even the power button doesn't work.
I've tried leaving the computer after, but even after an hour it's still the same. Nothing can be done when this occurs - no mouse movement and CTRL + ALT + DELETE doesn't work either.
Any ideas? I've used HDD life before and never encountered the problem.
