1. keep ur motherboard power regulator transistor, capacitor and chipset cool

2. keep ur hardisk temp below 40c

3. if possible turn off paging files,or get secondary hardisk to fill the paging files to minimize the pimary hdd load...

4. always clean ur pc with brush or vaccum cleaner (with the power plug pluged-in at off state <switch off but pulgged in>) to remove the electrostatic when u touch the component (make sure u touch the metal part 1st before toucing other component).

5. make sure u don use the pimary hdd to keep the torrent temp file...
