^^^weird bro, wtf!!

Could you be having any sort of condensation?

Let me tell you about something that happened to me.

I was running fine at 3.3 Ghz, my daily setting. Stable, and all of the sudden comp kept restarting. Brought down the clock, still. Default settings, still. I was like WTF. I have my pump and reservoir mounted inside my drive bays. The hose going back to the res was leaking drop by drop and it was rolling down the front of the case and shorting with my front case fan!!!!

I cleaned up the mess and re attached the hose well into the end of the barb and tie wrapped it. issue fixed and that was my problem.

Maybe you were having any sort of moisture or condensation that you were not seeing? What do you think?
