I am from Japan, and English is not my native language. However, because I have a great interest in electronics, I hope to engage in more discussions here with everyone. Currently, my experience is limited, so I may not be able to offer much, but I aspire to grow and eventually share my knowledge with others when I have the chance.Comment

Hello, my name is Daniel, from Argentina, I need to please ask a question to you, specialized people. I have a Dell Precision 7710, I want to buy a new, replacement motherboard. But I see many models. Can I buy any and will it be compatible? It doesn't matter if the difference is the speed of the processor, the important thing is that it is compatible. Can you guide me please?Comment
