I bought two multivision computers about 2 months back they had alot of problems. Including heating up. The other problems were solved, faulty memmory. But the heating problem was still there as there case has no good air flow and the heatsinks they use are very standard. So the soloution was that i changed the heat sinks for a better quality 1's. Because multivision do a few tests and the pc will pass on it. But when playin games before i changed the heat sinks, The Pc would shut down due to over heating. These pc's werent for my self but for a uncle. So if that information is any help because multivision wont do anything really because they said it was ok temp when they tested it.
