Q: my motherboard is Spark Kuroshio BA-210, using ADSL bandwidth. Recently it gets offline frequently, I doubt ADSL Modem has thermal problem, and it still would get offline even I blow the Modem with fan. Later I found the heat sink of the South Bridge chip on the motherboard overheats a lot, whether it is caused because of motherboard?
A: motherboard South Bridge chip takes charge of each I/O interface data transmission, and radiation badness would really lead to network abnormality. Now that you doubt about this, why not start from this aspect, you can try adding fan for main case or motherboard, cleaning up dust to enhance the thermal ability of the motherboard chip. Besides, network cable interface is of bad contact, severe interference on telephone line, motherboard/network card/Modem and other network devices work unstably, all these would lead to frequent network offline, you need to check carefully. For example, you can change one computer to dial, check whether it’s the computer problem or network problem. If it’s computer problem, focus on checking the motherboard and system; otherwise, suggest you contacting with bandwidth provider, asking professional technician to check.
