Some of your issues could be contributed to several things.
I am not using my usual computer at the moment because I am currently converting IPhone videos to wma files of Hurricane Irene on my usual computer, so I am using one of my other 7 computers and I am not used to this keyboard, so excuse my typing errors.
Back to the topic.
Your laptop could be over heating and is due for internal cleaning maintenance.
Your file system could be very fragmented and in need of running disk defrag if you have not used it lately.
You may have a lot of bulk on the laptop running in the background, you should try running MSCONFIG at the RUN menu and see how many un-needed programs are under the STARTUP menu and uncheck those that are not critical for safe operation of your laptop.
You can start those manually when needed.
If you have a close to full hard drive that to will slow down your computer, remove un-needed programs and bloatware programs that are simply taking up needed space.
How much RAM do you have in the laptop? Adding more RAM will increase the speed of your laptop because when you run low on RAM your hard drive has to act as virtual memory and that is slower then actual RAM.
Have your processor checked for the condition of thermal paste when you send it out, new paste will make a big difference and its better to do it now, so you won't have to worry about it in the future.
