Computer shuts off within 5 minutes of turning on

Specs: Windows 10, I7-3000 series, 16 gb
Hey guys, so as the title says, I can turn on my computer fine and then after 5 minutes it randomly shuts off. I tried cleaning the inside thinking maybe it was overheating, but the cpu temps are normal and I've never had a problem with this before. It worked for a bit after I cleaned it then started doing it again, so I opened up my computer again to find a liquid (I don't think it was water, doesn't smell like water) at the bottom of my case near the power supply but the power supply itself is not wet, is there something in the power supply that can leak and cause a problem? I have an i7-3000, 16gb of ram, amd 7970.

What consistency was the liquid? If it was slightly thick, it could be electrolyte leaking from the filter caps in your power supply. This could also explain why it shuts off after a few minutes. It sounds like a failing power supply.

Weird. How much liquid?

Do you happen to have a liquid cpu cooler? They're not commonly installed but if you have one and it was leaking that might be the cause.

Or could someone have messed with your computer?

It's a very thin liquid, like water. I found its coming from a part attached to my motherboard, all it says is master cooler, I believe it's the capacitor but I'm not sure. There's not series numbers on it or anything. EDIT: I looked on master cooler's website and I believe it is a liquid cooler

Electrolytic capacitors can leak but it tends to be thick. You cannot see well into the power supply but you can look at the capacitors on the motherboard to make sure it is not one/some of them. Use a strong light, the capacitors look like small cans or pots, should be smooth with no liquid, burn marks, or bulging. If the motherboard looks good then use HWMonitor or look into BIOS set up and look at all voltages, if any of the power voltages (12V, 5V, 3.3V) are off +/- more than 5% of their nominal values then it is likely the power supply that needs replacing. If ANY of the voltages are off more than that on the high side, shut down immediately and unplug because damage to components is very possible. Low voltages are also bad but not as immediately dangerous except losing anything you are working on when it quits.

You have to be a little bit crazy to keep you from going insane.

Take a picture of this and post it on Photo bucket or other and post a link to it here.

Are you sure it says Master Cooler and not Cooler Master?

Is this a custom built computer? How about some specs, if you know them.

Crossed answers while I was typing.

Self contained liquid coolers like this one:

I generally do not recommend but they do not often leak as far as I know. They should only be used by those who understand them and know what to look for. If it has leaked it should be replaced. I recommend getting a good quality air cooler instead since the good ones are very nearly as efficient at cooling and much safer. If you are not comfortable making the change out or selecting a replacement seek out help (though we will advise as needed).

Thanks for all your help guys! Sorry that was a typo! It definitely says cooler master. Here is a link as requested: https://imgur.com/gallery/YwD1V
Yes it is custom built off of cyberpower pc. The only specs I know are it's an i7-3000 series, 16 gb of ram, 2 tb HDD hardrive, an ad 7970 gpu and a Toshiba motherboard ( I wish I could get more information, but as I said I literally have less than 2 minutes when I boot up.)

If it is a cpu cooler that's leaking the computer may be shutting off because the cpu is getting too hot. Hopefully everything else is OK and replacing the cooler is all that's needed.

"The only specs I know are it's an i7-3000 series, 16 gb of ram, 2 tb HDD hardrive, an ad 7970 gpu and a Toshiba motherboard"

i7-3000 is the "family" & I doubt you have a Toshiba motherboard. Looking at the pic, why is the water block hanging off the side of the board? It appears you unscrewed it & moved it off the CPU. Your system will NOT run without the block being securely mounted AND with thermal paste between the CPU & block.

IMO, liquid cooling is a waste of money & can obviously damage a system if it fails & leaks. Even if your system is still under warranty, I doubt they'd honor it because you took it apart. I suggest you remove the liquid cooling & replace it with air cooling like the vast majority of the computing world uses. And in the future, stay away from CyberPower & iBuyPower PCs.
