I have an Acer Aspire 5735 Laptop, (The model with 4GB of RAM, a 500GB HDD and a T6400 CPU.) It's been starting to play up the last few months, it started with what I think was the Hard drive, which was making some weird noises, and it didn't sound like any noise it would make if it WAS the Hard drive, no clunking etc just random clicking. That went away after time, but recently my Laptop's been going really slow at random times. With just mIRC open the CPU usage can be anywhere from 20% to 98% (See picture in spoiler below.) Random CPU Usage spikes I don't know what to do anymore, my mum said she saw smoke coming out the back vent a few weeks ago but I thought she was just imagining it. Could the CPU be ...semi-fried or something? Is my Laptop dead? I've run multiple virus checks with multiple programs, defragged and everything etc. There's nothing wrong with it.
