Why does my PC reboot sometimes?

Episode 1422 (1:28:16)

Joseph from Riverside, CA

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.
