This is my first time starting my own thread so hopefully this is the right place to ask a question about my PC.

My PC is working fine last week,but starting 2 days ago,it started to shut down randomly.Sometime it last hours before shut down and sometime it shut down minutes after reboot.I read some thread and some people have encounter this problem but all of them seem to be have different solution.
At first I thought overheating is the problem,I downloaded speecy,core temp and my CPU and GPU seem to be at around 40-50c.I don't know much about the hardware because this is custom built and I ask the shop owner to set it up for me.All fan seem to be working fine,the light led on the mobo is on.I reckon there's a problem with the PSU but I don't have spared PSU.I bought this in 11/3/2014.So the warranty end last week.

One more thing,whenever I open up a game like Minecraft,Prototype,Crysis.It will shutdown immediately and before it working just fine.So help me please because my knowledge about computer is very little.

Spec:
Intel i3 2120
Nvidia GT 440
4GB of RAM
RS 460 PCAR D3 Cooler master
And an Asus motherboard.

http://www.cpuid.com/downloads/hwmonitor/1.25.zip - download this and unzip it

http://www.cpuid.com/softwares/hwmonitor.html - proof that the above is legitimate

look at the voltage that the power supply is providing to the motherboard - screenshot it and post it here

3v should be 2.9 to 3.1
5v should be 4.8 to 5.2
12v should be 11.52 to 12.48

Considering how the computer crashes when you start a game, if we can rule out the PSU by looking at the voltage then it is mostly likely the GPU
