I just bought a new computer. It is not a branded system, but all things are new. I had checked the same and bought. At the time of purchase the shopkeeper showed me the system is working fine, so later on to get more performance I asked to upgrade my ram. Later on when I started at home the system does not boot at all. I do not know why. I am not so good in this. Before taking this back to the shop what can be possibilities that I can try to fix it. I think the issue can be with the ram. It works well with the old ram. There is no display on the desktop neither there is any sound. I do not want to open the box, as it can void the warranty that I got with the system. I am not going to turn this back on, but want to know that what more things can effect in future if there is any particular hardware failure, and how to fix the same.
