My problem is that my pc keeps on shutting down. And after shutting down it won't start. I have got it tested once and they said it is a mobo problem.
I just wanted to know that, is there a problem with my config? Will the components work properly together?
You setup looks like it should be happy except for that PSU. I doubt it is your motherboard since I know of no mobo issues which would delay a restart attempt (really bad caps maybe?). The first thing I would suspect here is your PSU. That model PSU isn't the greatest and the symptoms you are describing seem to point to a faulty power supply (PSU overheating most likely). If you have to wait about 5-10 minutes before restarting, I would definately say it is the PSU that is your culprit.
C12Friedman, yes u are right. After 15 - 20 min pc will start if I push the power button. So what do u think I should do? Should I get a new psu of same brand with higher power or should I get a better psu with same power or with higher power?
Do u think my system is consuming higher power than the power given by the psu? Because in the psu's specs it says that the psu has 70% efficiency.
Actually, the review I read of that PSU (hardware secrets) wasn't very favorable and cautions against using it for anything more than 450W but you aren't close to that. I would recommend Corsair, Seasonic, Super Flower, XFX, Antec all as options but, before you decide to purchase a PSU, read reviews by such sites as HardwareSecrets, JonnyGuru, HardOCP and, AnandTech (actually just read the conclusion pages - the rest is fascinating only if you are into the ins and outs of PSU's). Looking at your build I'd say a 550W or better should do just fine - make sure it has your PCI connector(s).
