I've had an issue with my laptop : it randomly turns off when I play some games without even a blue screen or a crash of any sort.

It only happens with some specific games and happened a few times on each, something like once every several hours.

The games I've had these problems with are World of Warcraft, Call of Duty 2 and Civilisation 5.

At first I thought this could be caused by some sort of exception unhandled by my processor, but it would give me blue screens, not just my computer turning off.

 

I've read online that it could be caused to overheating but WoW worked just fine when I was using it on the same laptop with windows 8.1, and amongst all the other games I play on this pc, WoW, CoD 2 and Civ 5 are really not the ones that use the most ressources

 

Note that it doesn't turn off like it would by just shutting windows down, there's no windows 10 shut down screen or anything at all and the programs running don't close before. It just goes black instantly

 

 

I hope you guys can help me out and look forward for some answers :)

It may still be heat, even if it used to work.  How old is the laptop?  Has it ever been taken apart and cleaned.  I used to work on HP laptops and they would get a layer of lint over the radiator for the CPU, effectively acting as a blanket.  Normally the sign was the fans would always be running at high speed.

 

The other issue would be power, but normally you would see that in a desktop.

It's a bit older than a year.

I've installed a program to get info such as temperature of the gpu and it was almost 100°C so yes it should be heat.

I've tried dysassembling it some time ago but I can't manage to do it and don't want to break something so I didn't persevere. I think I'll take it to a shop to get it cleaned maybe.

 

Thanks for the answer

Maybe the system  stopped responding, crashed, or lost power.

 

Does it show any message after startup?

If the temp is at 100ºC - then it's definitely heat.

While laptop's tend to run hotter than desktops, it's just not right if they have temps higher than the low 80's

Most CPU's and video cards will shut down in the 100 to 105ºC range.

Although heat is probably the issue, I had the same problem. My processor was at normal temp, so it was a head scratcher. After thinking about it for a few hours i decided to check IRQ's and i had a conflict with my video card and my network card. 

I hope this is not your issue because it was kind of a pain to fix.

Let us know if the cleaning worked.

Way back in the Vista days we had a computer that would shut down randomly.

No one could figure out why.  We tracked the temps with a temp monitor for days without finding any problems.

Then one day I was poking around inside the case and I got a 2nd degree burn from the video card.

It turns out that the temp sensor had malfunctioned and it wasn't giving good readings.

it's common issue if the PC itself shut down by itself (meaning power off) its because it has pressure on the system and on board. so it can only fix this by shout down. so pressure on any part of PC e.g: CUP, GPU or RAM. Its will not ask you any thing its will automatic shutdown itself.​
