So my pc has started shutting off by itself.Clean install didnt fix the problem.I was advised to buy a new PSU.My current one is Corsair RMx Series 750W.My gpu is 770 and cpu is i3 3240.I think that a 500w psu will be good even if i want a future upgrade.What do you think?Can you suggest me a psu?Thanks in advance

I ran a windows memory diagnostic and said ram was okay :/
 


I usually start be taking temperatures during an AIDA64 stress test. We can do this here.

@JerryLP, Please download AIDA64 Extreme, drop down the Tools menu across the top, select System Stability Test, select everything except for local disk and run the test for ten minutes. Take a screenshot of the Clocks and Statistics tab every thirty seconds. Save these screenshots immediately; this way, if it crashes, we'll be able to tell if a component displayed abnormal behavior right before the crash.

Update: Make the test fullscreen so all stats fit on screen at once.

Well your CPU is not overheating, that's nice to know.

Please run the test again and provide a screenshot of the Statistics tab (not the Temperatures tab) so I can see what the software readings are for voltages across the board.

Your voltages also look fine. At this point, your CPU does not appear to be overheating and your power supply appears to be doing a pretty good job.

My next suspect is going to be your graphics card. Please download FurMark, as well as MSI Afterburner. Open Afterburner, make sure that the GPU clock, voltage and temperature are all on screen. Then run FurMark for ten minutes while Afterburner is also on screen. Please take a screenshot of Afterburner at the end of the ten minute test.

P.S. I apologize for how long this is taking.
