Surfinjo: It really looks like a power issue. especially since it is happening in particular areas. Your PSU is quite small.
Graphics games really push graphics cards hard. Sudden extra power can cause the PSU to simply switch off for a moment, timing goes and the system crashes.
You can try reducing the graphics right down.
If you built your own PC, it is a mistake to use a small PSU. Computer PSUs are demand devices, so they never draw more power than they need. In Sleep mode on my PC for example, mine only draws 1 watt. In general surfing, about 70 watts. In graphics games, it can draw 200 - 250 Watts.
Corsair is a good make, but it might have been better, with that set up, to go for something around 1000 watts.
If you bought your PC ready made, then it's a different matter. I seriously doubt any vendor will accept responsibility. It is very common for companys like PC World for example to give you inadequate PSUs.
Arcalmh: I had recently another PSU which it was worse than this one and I had no problem with that, and this PSU its almos new, it has 1-2 months, I never thought that it can make a game crash entirely, I'll try to reduce the graphics then and if it still happening I'll buy a new one, thanks for the answer!
At this stage, it would be sad and possibly silly to spend on a new PSU. Though ultimately, you probably will.
One point I should have mentioned, because it's easy to forget, do make sure the filter on the cooling input is clear. Many cases, (mine included), put the PSU at the bottom. This means it drags in its cooling air from under the case, picking up all the dust that falls on your desk. You got dandruff for example, you can see where that's going.
Before you do anything more, have a good look at your power connections to make sure they are sound. Pull them out then push them back again, but be careful.
Do all this in addition to reducing the graphics down and turning off unnecessary programs.
Most modern PSU, especially the larger ones have more than one group of supplies in the same case. The main power connections for the mother board of course, but other power cables can come from a different group. So you can try moving the load around.
If the PSU is modular. this is easier to see.
This link shows Corsair's modular range. I'm not recommending modular, particularly since they are more expensive, it's just to illustrate what I mean.
http://www.corsair.com/en-gb/power-supply-units/popular-power-supply-units/modular-psus This next link I do urge you to read. Tom's Hardware is a respected source. In particular, the section of efficiencys.
http://www.tomshardware.co.uk/faq/id-1936217/install-power-supply-including-basic-cable-management.html There is a facility in windows for looking at errors. I'm reluctant to use it very often and even less to recommend it, simply because it is so general and obtuse.
You can find it by entering Event Viewer in your search box. Under the Heading Custom Views, click Administrative Events. I will warn you get a lot of false leads there and looking up the event numbers can be very frustrating, especially when they are obsolete.
But it may give you some leads. If you wish you could post an image of this next time you get a crash.
Anyway, I do wish you good lick and hope you will say how you are getting on.
