That beep code symbolizes memory failure, and or video failure.

Replacing the RAM should fix your issue.

You have 2GB of RAM preinstalled unless you replaced it.

https://www.amazon.com/dp/B00C538B56

In that link you can buy a 4GB kit, of the RAM that your laptop supports and fits. It is actually more RAM than you have now.

2GB x2 sticks. Try doing so. Pretty cheap as its old ram models. Only 17$

Could be cheaper on EBAY as well. Just makes sure it is that. (The link I provided)

PS. This should fix and boost your Laptop.
