I bought the second hand laptop from my friend because I wanted to save some money. However that computer really caused a lot of troubles for me. My wireless always down when I was in the middle of important projects. This laptop also got virus, when I clicked on internet explorer, it also almost took 10 minutes to get on the page. After I brought my laptop to Geek Aid, They were fast and Professional. They helped me to reinstall the operating system, and newest anti virus software. Thanks Geek Aid, I really appreciate your help!!
