PC turns off randomly

[Hemanth_10]

When I was playing DotA 2 the PC suddenly turned off and from smps a big spark and after that I try to turn on but no luck. So after that I planed to change the smps there was an another one in old computer so I take that and connect now my PC turns on but after that if run any kind of application even groove music ( iam running win 10 . The PC shutdown.
But one thing I can note is CPU fan is running and power blue light is also glowing . I think CPU is heating also.
No graphics card installed.only 2gigs of ram

That wasn't wise thing (to put it mildly) to do after a spark, what possessed you to do that????
Better don't play with things like that, change PSU to something known good and of adequate power. Count your lucky stars if nothing else burned out.

What are your pc specifications and since how long you are playing dota2 (i mean since how many days)?
Also run 'dxdiag' in run window and check approx. Memory under video tab.

Is the power supply cable all the way in? If you move it around then its not in also does your place of living have enough power to power your PC? Are the cables messed up? Check all of this
