lumia 520 is restarting in 2-3 minutes or while opening any app

Hi,

some days back, i have changed my power button as it was not working.

After changing it,. also, some setting with battery connector has done by the repairing guy, phone worked for two days.

suddenly one day, i lost my coverage & then after phone has started restarting.

i tried changing battery & power button, it worked for half an hour but after that same problem has continued.

i tried re-installing s/w too. But when new s/w is getting loaded , phone restarting and make sw re- installation failed.

If you had it repaired by Nokia/ MS authorized center, you might want to go back and have them checked it again?
