Upon re-booting it will work fine for a while (seemingly dependent on whether my wifi card is active or not)and then the same thing will happen.
The clicking and wifi card suggest a hardware problem to me but I'd like to know what to do (if anything) to fix this Vista need to check C-Drive for consistency. I know I can turn off the auto check through CMD but that won't -fix- whatever is wrong. So any suggestions would be appreciated. My thanks.
