I know you've blown the dust out but apparently to do it right you have to remove the shield. Some discussion here:

http://en.community.dell.com/suppor...

Also a recommended replacement from there of a Geforce 440.

The gts 240 is an OEM card used by Dell and maybe some others. I looked on Dell's site for driver support for that card and could only find drivers for up to windows 7. Nvidia does have a Geforce windows 10 driver--version 341.74--that would work. I can't give a direct link but start here:

http://www.geforce.com/drivers

The automatic update or auto-detect gpu would probably work but if you do the manual search the options on the right would be:

Geforce
Geforce 200 series
Geforce GTS 240
Window 10 64 bit (it's the same download for 32 bit)
English
All

Edit Oh well, here a direct download link:

So either a good cleaning, card replacement or driver update should get it going.

take side cover off its a desktop.blow out all dust with a can of air.its probably getting hot fans pick up speed when clogged up with dust and speed up to try to cool down.

Does it do the same thing in safe mode? Do you have windows 10 video drivers installed? Also check the power settings--monitor shutoff, sleep/hibernate--and see if those might be a cause.

is your monitor plug to on board video or to a video card ? is a video card try plugging it into another video outlet on the computer.if you have one maybe video is going out or the video card is.but regular on board may still work.also sometimes if video card if installed has a fan on it it can also get clogged with dust.just trying to cover all bases.

It does do the same thing sometimes and I have all the windows 10 driver updates, I checked today. And I don't have any of those other things

It's connected to the graphics card

Btw I tried the program that tests your video card to the limts, and when I did it the screen shuts off again
(Just checked and it's called FurMark

I'm going to try to take the cover off the GPU and clean it but installed the nvidia Windows 10 drivers do it can't be that. Probably the only way is to buy a new graphics card

Edit: I opened the shield and saw a wall of dust blocking the heat sink. i cleaned it and ran fur mark again. It didn't crash! I don't know if it fixed or not but i will further test it.

Hopefully that was it then. Another possibility is an aging power supply. According to the specs for that card it can draw up to 120 watts and a power supply of at least 450 watts is recommended. I don't know what you're using now but if it's somewhere around 450 watts (or even less) you might want to consider a new one.

But keep us updated.

THX the cleaning worked. I've been testing it, trying to make it crash and it never did. so i think it fixed it

Great! That was a relatively easy fix assuming it holds.
