A few years ago the vent that leads directly to the CPU was completely dusty. so I heard pledge 'kills allergens" so I sprayed it directly into the vent, whole can. Now the computer lags at intervals and stutters on everything (CPU Usage spikes to 100% every few minutes for 30 seconds) and it's gotten worse. Games are unplayable. I've replaced the graphics card and it still lags.
