Server keeps freezing/crashing computer

I've been running into an issue whenever I play on my Minecraft server. Sometimes, it'll just crash, and then when I relaunch it my computer freezes, even the LED's on my keyboard. Last night, I uninstalled Java and reinstalled it, and it worked fine. But it happened again this morning.
