I bought a laptop from jarir but I don't have any problems until now. I believe your problem was about software and not hardware. If your running in windows and if there is a notification about "WINDOWS UPDATE", please update your system. People have issues with there laptops because they stop the updates or not installed any virus programs that protect the computer. And also when people surfs the net they just install and install without knowing what's the purpose of the program they are installing that's why they end up with a faulty system. Also a problem with the people in sales is that they don't know how to explain to people about the products and issues concerning to it.
