This is recurring with more regularity. Anyone else have this problem?
Hardware & Technical PC switches off!

Check your CPU and GPU heatsink / fans and your power supply unit.
95% of the time when this happens, you are overheating something and the PC is auto-shutting down when it reaches a temperature threshold to prevent hardware damage.
Download something like speedfan and check your temperatures.

In addition to heat, it's possibly a power-supply issue. Your computer could be fine while idle/using desktop applications, but when you load a game, the power draw from the CPU and video card exceed what can be reliably put out by the power supply, and the PC shuts off.
Where do I go to check(possibly adjust) what my Temp Threshold is on my CPU?
This ^^^^
Just download an app that lets you check your temperatures. Then look up your CPU / GPU and see what temps they should be running at - if your actual temps under load are much higher; there is your problem. And as the original reply stated, check your fans too to ensure they're running.
And you don't get to adjust your thresholds as far as I know. If its a heat problem, your machine is shutting down for a very good reason. And its because something is wrong with your cooling, not because you need to adjust a threshold.
Opened up my lappy to find dust caked all over the fans. Dust be gone now, see whats next.
Intel Core i7-2630QM CPU @ 2.00 GHz

Did it again. Fans run fine but still overheating issue.

So it's a laptop - have you cleaned out the cooling fan inlet / exhaust lately?

It could be a battery problem among other things. To test to see if it's your battery, I would take the battery out and just power the laptop with the charger.
Feel underneath the lap top for heat if it is hot to touch, i would suggest that you get your laptop serviced ASAP. If you wait, you may fry the motherboard.

Overheating can damage things. Especially in a laptop which run hotter anyway. Now that you got the dust out. Make sure that all the fans are turning. How did you remove the dust? Canned air, or did you just use a brush or your breath. When dust is "Caked" on the fans, it may also be blocking passages in the heatsinks. Get some canned air and make sure you blow out all he heatsinks really well. From the sides, not just the top. Stick the little tube in there and do a real good job.
Don't use canned air near the fans it can over rev them and blow dust in the bearings etc.
It's a new battery, less than a month old.

Done it, still overheating.

Have you got V.Sync switched on? If not, I would suggest that you do.
Can you tweak the GPU speed - it may be that reducing the maximum clock on the GPU might reduce heat output sufficiently to stop the (what seems to be a thermal overload) problem.
Assuming your equipment is OK what you need is a cooler management and monitor program.
One of the best and which I use is this: http://www.majorgeeks.com/files/details/speedfan.html
Download it and I will write a set of instructions to use it.
Please don't play with anything for now. Most of what you see is incomprehensible and some of it can cause problems if you don't do it right.
Back asap.
Though I haven't used it myself, it seems Speedfan offers a configuration service for a number of boards.
