Thanks for the help... It's probably the hard drive, the fans sound like they are working correctly now. I definitely leave the CPU on way too much.
I think it's like a 2 year old laptop, it's a HP pavilion dv5000, I thought it was a beast but I may be wrong
I was wanting a new computer anyway, a desktop instead, I will do some troubleshooting here in the next few days and see if I don't have to pay too much to get it fixed though.

Once again, thanks for the help everybody.
