Computer turning itself off.

Hey folks, I'm not very tech savvy so thought I'd ask on here before being charged silly money for taking my computer into a shop.

I've had this computer for 15 months now and have never had a problem with it. It's a lot level gaming computer, plays games like AC, WoW and Borderlands smoothly on medium/sometimes lower settings, so it's always gotten me by.

However, recently (in the past month since I started playing WoW again) it has been spontaneously turning itself off, no "shutting down" screen, nothing, just turning itself totally off instantly without warning.
It does this about once or twice per day, and I use my computer quite heavily throughout the day, always playing WoW or something similar.

God damn you breakups.

Any help would be appreciated, thank you!

It's over heating. Same happened to me.

Try 2 things.

First, try and keep it elevated and in a cool, ventilated area when gaming. You may need to open it up to clean the fan.

And check if the battery is showing any problems.

Ah smashing thank you so much! Just had a look as the fan and could see a fair amount of dust gathering. Will be sure to clean it thoroughly.

Thank you again

When you're playing a game, run HWmonitor
What are the temperatures? It's most likely an overheating issue.

Is this is laptop?
Be incredibly careful when you do clear it out. What I did a few years back for a relatives failing laptop was the same thing but also changed the thermal paste to improve heat dissipation.

As the previous guy said, I think he's talking about a desktop computer.

Check the dust on the fan and generally in the case, try clearing it as much as you can. If there's a lot just take it outside. It's rather annoying because there are places that have a lot of dust without being able to get to it. Just keep all the case fans clear too.

Check the cable managment of the system. Poorly wired cables will decrease the airflow within the case. A case should have at least 1 exhaust fan although it's always good to have more. (Exhaust meaning blowing air out of the case).

The other thing is depending on what CPU you have, and if you are using an aftermarket heatsink on top of your CPU, the thermal paste might of burnt off, too much, too little.. It's a difficult process to perfect the right amount. Thermal paste is a layer of thermal grease, it's a kind of thermal conductive (but usually electrically insulating) adhesive. It's unlikely it would have burnt off in the 15 months you've had it but depends on the quality, purity and other factors of the thermal compound.

Definitely switching off due to overheating problems.

Try downloading SpeedFan, it monitors your temperatures of all of your hardware from motherboard, to graphics card to CPU and hard drives. It also has a feature of PWM control (Pulse Width Modulation) and overrides the BIOS control speeds to keep your fan speeds optimum to the temperature of the hardware e.g CPU very hot = run fan at 100% capacity.

Edit: I'd say anything over 75°C on a CPU is rather too high. Especially for long periods. Although this differs for every CPU but use speedfan to find out temperatures.
