Just lately my PC has been running amazingly slow,I've been through it with various reg cleaners,anti virus programs and system optimizers but with no luck,so I resorted to formating and re-installing,bingo,problem solved,or so I thought,over the next couple of hours my PC has gradually started to decline again:confused: is it dying a slow death or could there be another problem?

Did you try a defrag?

Yep,defraged it,I've done the works,at a bit of loss at the minute asto what to do next.

Sounds like you need to do some serious FOCUSED maintenance.
