PC restarts itself

[justiceknight]

Context: recently Mboard spoilt, went for replacement, repairguy also changed PSU at the last minute (I just trust him cos I'm a noob) . So now the pc restarts sometimes whenever I am playing a game

problem: I only opened 1 firefox and 1 (Overwatch/League of legends) and the restart occurs

I read a bit on PSU troubleshoot and most likely its PSU problem but still not sure cos I'm a noob. let me know what I should do.

Could be as simple as incomplete application of thermal paste on CPU. Peeling label makes me think PSU is running too hot - is it venting properly? The Seasonic is a well known brand - but I do not know iCute.

If you are testing, you may want to run your hardware utility in a window that you watch while you increase the programs. You may see spiking temperatures.

I would go back to the repairguy and explain what is happening and your concern that something is 'overlooked' - but you do not wish to spend much more since he had 'fixed it'.

how do I do this

Select what seems best utility (https://www.techspot.com/downloads/optimization/) for the job. I have used https://www.techspot.com/downloads/5245-hwinfo64.html among others.

Start utility and select temperature reports that you want. Set this as a window. Start your browser and set that in a window so you can see both at once. Add browser windows (YouTube, etc) while monitoring temperatures. If it spikes, you may have learned what is causing your problem.

Don't take too long...you should have some kind of warranty from the 'repairguy'... and it does not seem that the repair is complete yet.

One tab or 2 tabs at max firefox will be enough as both of them take up more memory per tab.
Be sure to open up task manager, put it on the left side of the screen.
Download HWMONITOR from here:

That iCute Power supply is of poor quality people mentioned at other different forums or sites
Take it back by the end of this week.
Politely ask or directly force your computer technician to put in the psu you want.

Do this for me and bring it back here soon:
*Type in event viewer.exe in cortana search bar.
*Click on windows logs, next double click on system logs.
*Expand the window for event viewer, find the dates where it crashed.
*Screen shot the window or take a picture and show it to us.

In all honesty I think the problem is with nvidia drivers and the crap-tastic psu you have currently.
