Windows 10: Monitors turn off and every system fan goes full speed

Hello!

I'm typing this as quickly as possible so I can get this up in time before my pc dies again.

For no specific reason, my custom-built computer will just shut off the monitors and then every fan goes beserk. This happens during no specific task. Whether it be playing a game, typing a document, or just watching a youtube video. The power supply makes the most noise, and I've run diagnostics on every hard drive I have. I've also scanned for viruses, too.

This all happened after I came back from vacation. Keep in mind that I was gone for 6 days with no issues prior to returning; I came back, turned it on, and played some Metro Last Light and all of the sudden, it just happened. I have no idea what's causing this and the longest it has gone without going crazy is around a hour.

Thanks in advance.

:)

 

My pc fan all of a sudden gets stuck on max sped

I was just doing some internet surfing and all of a sudden my fan goes up speed a little bit every 2 seconds and then now no matter what, it stays on max speed even after turning it off and on again

 

Fan speed problems on ASUS ux501 (Windows 10)

"Turned on passive mode... So this makes trottling"

The gpu temperature monitor shows the temps are too high (Nvidia gpu's usually don't throttle below 100C ) ?

Do you have the Nvidia card set to 'prefer maximum performance' in Nivida Control Panel ?

(Not good for battery charge, but the better option when plugged in and running games ).

I don't have a laptop, but would think that using passive mode may lead to this 0 - 100 fan speed .

Is there another more aggressive speed mode you can use ?

I've had graphics cards in the past that came with profiles that were meant to be quiet, and they were if you

didn't stress the gpu, but this meant the fan speed curve held back on the fan speed too long, which leads to frequent

cycling up and down' of the fan speed when the card is working hard. Very annoying, and inefficient for cooling

under full load.

In this instance a fan speed control software will allow you to create your own custom fan speed profile

to force the fan to run faster at a lower temp.

A lot of recent desktop gpu's keep the fan's off when the card is not being stressed, but I wouldn't have thought

that a laptop would do this, as they are notorious for running hot.

Not sure if it matters, but I got a new keyboard for christmas. Not sure if it's the problem, but I'm trying it out right now.

 

I'm thinking the 'long' inactivity was an invitation to critters to nest in a new home.

When monitor turns off, that's usually a graphics card's response to trouble.

When fans go full speed, temperature is too high.

Pest control needs to look inside the box to see if some component is not right, ex. fan not spinning or card too hot.
