Laptop slow [tried almost everything]

My Laptop is getting slower and slower. I is almost 5 years old now. I am dual booting Windows 7 and Ubuntu 12.04. On the Windows side, I have two partitions and both have plenty of space. I did a full scan with Avast and Malwarebyte and no virus is found. I tried to clean out the temp and other trash using Ccleaner, defrag the HHD, disable aero and almost other stuff that I can do besides disabling my wallpaper (which I know doesn't make a big difference in performances) What happen to my computer? Is it the CPU normally slows down over time? Or other things?
If I want to reinstall the windows, what is the proper way to do? Since I'm dual booting.

intel 4004,

Have you monitored your cpu temperature during operation? CoreTemp should work, as should HWiNFO.

If your cpu is getting too hot it will throttle back to prevent damage. If it is getting hot, then perhaps your heatsink is clogged with lint and dust.

With the laptop performing a task that loads the cpu, hold the backs of your fingers to the exhaust port. You should be able to feel the hot air coming out.

If you don't feel any airflow, you may use canned air to blow into the exhaust port and see if a bunch of stuff comes out of the intake port. It's best to disassemble the laptop to do this, but it can be a tedious process. I always blow into the outlet because the dust accumulates on the leading edges of the fins and not between them.

I may be over cautious, but I usually put something (toothpick, bread tie, whatever will fit) into the fan to keep it from spinning and generating a potentially harmful voltage.

Have you tried running system restore:System Restore

When I check Core temp, its around 62c - 73c. I can feel air flowing. I cleaned the dust out before using a brush and a vacuum cleaner.

So system restore means make the computer go back in time? But you will need a store point right? I don't have a restore point...

Forgot to say, I'm using two accounts. One is the Admin that a activated and the other is a normal user.

Does it run slower in Windows and Ubuntu or only in Windows. Just to see whether it could be a hardware problem or an OS problem.

From my feeling, Windows is running slower. Ubuntu because it has a very limited space, its a bit slow, but not as slow as Windows side.

I had the understanding that there was a change over time. Did both change (get slower) or only Windows. I am just tryung to find out whether we are looking at a hardware or OS problem. What is your feeling??

I guess maybe the Harddrive? I didn't notice any changes for Ubuntu, only Windows.
