NIve seen a few posts, but I am not really sure if my issue is similar or not. Every single time I run HWInfo it gets to the IDE scanning part and causes my computer to freeze up and crash. It forces me to have to hard reboot my PC.
First check S.M.A.R.T. attributes 203 - if not zero them check IDE/power cables, double use HDD check tools like Victoria 3.5.2 for DOS (not Windows! - for correct diagnostic tools needed direct access to IDE port!). Use attached bootable ISO for make CD-ROM/Flash and diag You HDD.
