There is nothing to these things Super cheap, thought this would be a good buy but it wasn't. If you need support they will reply but basically tell you to do the same things over and over. I have tried a new ssd and ram but still issues, nothing left in this box except motherboard. I have tried even installing windows 8 thinking the latest 10 might be the issue and more goofy errors. I wanted to update the bios to the latest but there isn't any updates I can find.So to issue a RMA they want you to lie to customs when sending it to China which I will not do. I contacted Amazon and they could care less that a seller wants you to lie to both your country and the receiving country, not sure what the punishment is in but I am not willing to find out. Lesson learned do not buy JUNK.
