OK, I just got a call from my brother that he's been having a lot of issues with his computer. Blue screens and network issues, specifically. Specs: Q9550 CPU, HD 4870X2 gfx, 1kW Tagan PSU, a whole load of HDDs, Arctic Freezer 7 cooler, CoolerMaster Cosmos 1000 case. ASUS MoBo, but I can't remember the model number. BSoDs, I don't know how to read crash dump reports, so I'll upload them when I'm home from work for Rydian or anybody else well versed in crash dumps to kindly analyse for me. Network issues, intermittent or constant dropping of network signal. It's connected via HomePlug for now, which he says is the cause of it. It does have WiFi built into the MoBo, but the signal is too weak to work properly. We also have an ethernet cable running up the stairs that he's using now, but Ethernet is not ideal. I'll need to determine if the HomePlug is really causing it, and if so, how to fix it. I'll post more details as I find out, when I'm home from work. Any help is greatly appreciated.
