How do I check if my cooler is seated properly?

For the last week, it has been getting hotter as the laptop runs for longer and I have found it has been getting slower.

Specs:

Intel Core i5 M460 - 2.53Ghz

8GB RAM

500GB HDD

NVidia GeForce GT 420M

Yes of course, here you go...

Hey

Recently, I have had a problem that my CPU is using about 50% when idle and the core temperature is about 80 C. I have run cccleaner, malwarebytes, spybot and I have defragged the hard disk but nothing seems to work. Heres a picture so you can see for yourself:

Any ideas on what to do to rectify the problem?

How do I check my BIOS?

I do at the moment I use CCleaner, Spybot, Malwarebytes and defraggler. I just don't update drivers

Today I'm doing a "service" on my laptop and I am downloading the latest drivers for my Graphics Card. This got me wondering what else I should download drivers for?

Yes, at the moment I have my main controller with no battery pack wired to the console because its the best chance of having the console recognise a controller

Recently I am having some issues with my xbox 360 controllers. I have 3 wireless controllers and sometimes they will connect and sometimes they will not, if they won't, it doesnt matter how many times I try to sync the console will not pick them up. I also have a charge and play kit, at the moment I have one of the controllers wired to the xbox, and I can turn on the xbox using the wired controller but then It sometimes will not register the controller.

Any ideas?
