Joseph built his own gaming PC but every once in awhile it reboots itself. Leo says it could be updating itself. But it also may be that a component isn't working well when it's cold, but when it heats up, it will work just fine. So an errant solder could be the culprit. It sounds like a hardware issue. Joseph should keep in mind that when he builds his own PC, he is his own tech support. He should check out the motherboard manufacturer and see if there's a recall.
Elliot's Mac died and now he has to use an old Windows machine. What can he do to speed it up? Leo says that Elliot is the prime candidate for a Raspberry Pi 2 computer. At $35, he can't beat it. And it runs on Linux.
Elliot wants to game, though, and he plays Gary's Mod a lot. There is also Steam for Linux, but he might not be able to get Gary's Mod on that. If he needs a decent computer, it all comes down to budget. Leo says he can also put Windows 10 on a Raspberry Pi, but it won't be very good with graphics.
