Computer Shutting Down

Megapuppy

Recently, when I try to turn on my Home PC, it boots up about halfway into Windows and then spontaneously shuts off without any error messages. If I hit the power button again, it turns off even sooner. If I let it sit for a few minutes, it will get about halfway through bootup again, but still just turns off.

I suspect that it is an issue with the power supply, but my technical knowledge doesn't extend very far.

It's a home-built PC with parts from newegg, and this is the first problem I've had with it Since I've owned it for a year and a half.

Could be the power supply. Could be something else. If I were you I'd try the ol' "boot again and again slowly adding components" method.

First boot the computer with just Mobo and Ram. If that doesn't work you know it's either one of those or the PSU.

Then add the graphics card

Then add the hard drive.

And so on.

Also check your fans. If your CPU fan is broken that might be the problem. Modern CPUs will usually shut themselves down rather then burn themselves out.

Sounds like power regulation issue. Probably power supply but it could be a fault in your mobo (capacitor probably).

Yep, definitely sounds like a power supply issue, if it's literally TURNING itself off, at a certain point.

It should take longer than the boot-up cycle to overheat a passively-cooled processor.

Mine did this exact thing, and it turned out that it suffered a power surge of some kind and couldn't recover. And this is with a decent Surge Protector.

I had to replace the majority of my components and put my PC on a UPS (basically a fancy surge protector with a battery to help filter and correct ups and downs in the line).

I'm still in class, so i can't try that out, but in regards to the other suggestions, I'm pretty sure it's not a heat issue since all of my fans are working fine.
