Packard Bell Easynote C3300?

Update from above thanks for your answer I have checked and the fan as everything else is dust free.
On advise from someone else I deleted the operating system and rebooted with Ubuntu the strange thing is that although the laptop stays on now it's so slow it's ridiculous it takes a full 10 min to go from pressing the on button to Ubuntu being fully loaded and working then anything I press takes 5 min to actually do anything.

NO thermal paste at all? It's strange.
Anyway, you don't need new thermal paste if you don't actualy remove the heat sink.
The only normal concern is dust buildup and fan failure.
Check for dust under the fan. It's the worst place it can be.

Make sure that the heat sink is properly seated with a very thin layer of thermal paste between it and the CPU.
The thermal compound purpose is to fill any eventual air gap between the CPU and the heat sink. It's less conductive than direct metal-metal contact, but much beter than air.

The heat sink should be held in place over the CPU by a metallic clip or some other mean, like bolt like rods going through the mother board. It MUST rest flat and firmly on top of the CPU.
