Sony VGN-SZ491N Ram
Random Access Memory is considered volatile memory as all the information held gets blanked out every time you turn your laptop off. The clock speed of the RAM is imposed within the specs of the motherboard, while the actual storage size is determined by the software. Your laptop RAM stores pieces of information that the central processing unit uses for programs. Because RAM is only temporary storage for the CPU, it does not have the ability to store files such as text documents or movies. But, it has a positive impact on the speed of your laptop. RAM is necessary even for your laptop to even boot. If there is ever a doubt, remember that bigger is always better!

- You tend to have access errors on your laptop intermittently
- Silence as you boot up your system
- The screen will not turn on when booting up
