Your question is very generic. We'll need specifics to help.
1) Desktop or Laptop?
2) Make and model of machine if not generic?
3) If generic we have to open it up and see what ram is already installed to see what kind of ram we'll need
You can't just buy any desktop or laptop ram. They have different speeds and different physical shapes, so you'll need one that is of the speed and shape that your motherboard supports. These are standard numbers so that once you have the answers to question 1, 2, and 3 you should easily find at a computer shop.
This a freezing of the system caused by the small memory (Ram memory ) or too many programs running in the same time for the capacity of the Ram ..or the CPU ..or just one faulty program or application ...Freezing the screen can be also a issue of running a program that requires video card resources much larger than available ..You should pay attention on the programs running often when the freezing is happening ..and than search on the internet for minimum requiring resources for running that application ..If the system permits you should upgrade..at least the Ram memory for to avoid this happening ..or use similar application with less needs from the system .. Another cause can be the system being infected and in this case you should reinstall the operation system ..(this is probably the cause if your system has at least 1G of ram ..and 2G CPU ..cause in this case it is enough to run common application of any kind except complicated video ones..and the cause for freezing is a virus )
You need to find right drivers for your laptop .
search on google as " windows drivers for acer travel mate 5520 " if you do not know how to install drivers let me know .
scan you system with an anit virus as well
