Hello everyone

My computer shutdown started during game from a few days ago, I choose the saving mode from power plan(idk english mean). Computer didnt shutdown a few day after saving mode, but my computer shutdown again started. I applied thermal paste to CPU and GPU(i mean graphics card. This may not right), I cleaned the fan with vacuum cleaner. Computer again shutdown after this all clean process. I dont understand it.

I know you replaced the thermal paste on both of your components but check the temps again in-game to make sure if you did it accurately.

@user Masea: I tried temp in league of legends and it was 91 temps on performance mode. I saw that and choose the saving mode. It was grow up till 73 temps. I told to tried on performance mode but it was 91 in the 1st minute. I chose the saving mode when i saw that value. Now computer not shutdown on saving mode but i doubt to next days to that. If you have idea to me, please tell me and thank for answer.

@user phalenkO:
Make your own power plan.
Max for GPU, less for CPU.
Enable VSync or enable FPS cap.

Most likely it's CPU related issue. What's the model?

You applied thermal paste to the GPU? Where exactly? You shouldn't do that.

The only right place for thermal paste is on top of the CPU (between CPU and CPU cooling unit / fan). And normally there should be something already. So if you apply new thermal paste you should remove the old stuff first otherwise things may become worse.

What are your specs? Did you update your GPU driver? Did you make any changes to you system or install any software before games started to crash? What games exactly are crashing?

Why not DC? I replaced GPU's thermal paste too, of course only if the brand allows to remove the fans, because otherwise the warranty void, but it can be done and it's as good as for the GPU as you would do for a CPU. There is a specific type of "paste" that you should not apply to GPU for example unless you are professional, but normal paste can go onto the CPU without any issue.

Oh god, one of those "i broke something instead of fixing it" threads.

I still don't know if those values you are getting are after you replaced the thermal paste or not. If that's the case, you most probably did it wrong because they are dramatically high. As they say it, the thermal paste should be spread evenly over all the points of the surface and to do that, they typically pour a little amount of the paste into the middle of the surface and subsequently closing the heatsink on top of it will eventually spread it evenly all over the surface. I am not telling the process of cleaning the old thermal paste before doing all that, as you would have already done that anyway.

Watch a few videos on YouTube covering the related process, pretty sure you are going to find some that will work for you. Or bringing it to the nearest local computer service would also get the job done.

@user Marcell: Okay, you're right that makes sense. Nearly all desktop GPUs however are fully assembled units with thermal solution built in so I don't see any good reason to mess with that. Unless you're doing some crazy overclocking or want to replace the fans with water cooling or something like that.

Would never mess with it as an attempt to fix crashes though (if that GPU is used normally without prior modifications like a custom cooling solution).

Do you have an Intel CPU? I heard this happens due to thermal meltdown with their components.
How old is your PC? It's possible that your power supply is old and is stressed too much by your hardware.
You don't provide too much info, we can only guess what's going on. At this point you can only really try out replacing different parts to try and find the broken part.

1. Post your specs here
2. check temp during playing
3. might be a bad PSU ( Power supply unit) check voltages on +12v +5v and +3.3v

@user Assassin moder: I got till 80 temp during game. Computer was now working from PSU or battery, but it worked spontaneously. I measure with voltmeter and there's not any value. I was touch on finger and wait a few minute, there's a value between 18-19W. Then computer worked.
@user VADemon: Yeah I have an Intel CPU. I was buy in the 2015.

I applied thermal paste again and plugged the ram into another socket 'cause it very close to cpu and gpu cooling pipe(idk this mean). Then I tried and computer shutdown again. AMD Raedon setting came to my mind. I went to graphics card profile in AMD Readon setting and choose the standart mode. Now computer doesnt shutdown in games but this may for now. Very thank you for answer.:) If you have seen a thing please tell me.

So its a laptop.. GPU might be overheating and shutting down to prevent damage,
btw that kind of protection is stupid for me because hot silica getting not cooled down right might crack

@user phalenkO: hm what mode did you set your GPU before "normal"? Let's hope it will work fine now

This is fine. Although the existing energy (heat) will propagate throughout the chip after shutdown, it will not heat up any more. And rapid thermal cycling (too fast cooling down) will actually put more stress on the material.

Buy a new power supply. The whole reason is in it.

@user HESY: it might be bad VRM of CPU, GPU or board itself. PSU might be not bad, but trying known good might help diagnose the problem
