This post will be long so I apologise, it's about a water leak that soaked almost every component in my PC and I want to find out why it did not kill it. So if you don't know a lot about water cooling, please don't waste your time 
Yesterday I was playing a game of CS:GO when suddenly my graphics card showed a bunch of artifacts and purple lines and multi-coloured square boxes, I assumed it was my GPU having a fit since it does that sometimes but mostly I get a black screen because the card is old so I just restarted my system normally as I do.
I pressed restart button and when my system restarted, I could already see the multi-coloured square boxes on my post screen again and there was some sort of error on Windows saying that there was a hardware failure or such so I assumed it was a dead graphics card and then system went into repair. This is when I looked on my PC to find out that there was leak so first thing I did was reach for the PSU switch.
It turned out that a CPU block hose popped off half way and started squrting coolen onto the motherboard and it would leak down onto the PCIe slot and onto the card, then it would drip from the card on top of the power supply and onto the bottom of the case. (later turned out after checking my temp logs, my temps reached 102c on CPU and GPU because my pump failed, which caused the hoes to get hot and expand and start sliding off.)
I was sure the PC was completly dead but I started drying it out anyway, I had to take of heatsinks for things such as south bridge because the coolent got even behind it. I took out the CPU and luckly the coolent did not get into the socket but there was ton of coolent behind the water block so I fell luckly.
I was running SLI setup and the top card got completely soaked while the second had very little so I decided to take out the top card, drying it out as much as I can and then leave it for a week to dry out so I switched my second card into my main spot. I had to blow dry the PCIe express socket since it was completely soaked. The water leak happened at 5pm and I ended up drying everything and putting everything together at around 9pm, this is when I tried to boot the PC and it would turn on for split of a second and it carried on doing this. I assumed I placed the CPU wrongly when I took it out and since I was really annoyed at the time I just went to bed to chill out but I fell asleep anyway.
I woke up at around 3am and started working back on the PC, I first tested the PSU which did excatly same thing so something was shorting out, turned out it was my hardrive which I'm aware of it, it has a bad power connector, so I unplugged it and turned on the PC and vola, it booted perfectly fine without issues.
I have no idea how the PC survived since the PCIe slot was completely soaked, I had to plug in my GPU, then unplug it, wipe the contact, put it back in and repeat so I can dry the slot. I had to do that about 20 times. Everything does work and to make sure the dry everything I can, I will run the PC at full load and lower the speed fans on rads so it can get a bit toasty, make around 75c so any coolent left such as on the GPU can evaporate.
I am running 60% anti-freeze with 40% distilled water which left me wondering, if anti-freeze saved the PC?
