I have an HP Probook 4740s running windows 7 Professional which came with 4GB of RAM.
I just upgraded the RAM by adding another 8GB in the free slot.
However, Windows now takes a lot longer to start up (feels like about 3 times or more).
In addition, applications seem to respond more sluggishly.
Windows (in the My Computer properties) is reporting 12GB of RAM.
I didn't expect that the laptop would be faster, only to be able to run more programs comfortably without swapping slowing it down when switching between them (as I was maxing out the available memory already). I did not expect Windows to perform worse.
Can you think of any reasons why it could hamper performance?

and go to properties to find it)? If you went over the motherboards limit for max RAM that could cause the problem.
