hi
my computer cuts power off whenever i play pc games or open facebook account.
i m using windows 10 os and have 3 gb ram memory.
for online game it doesn't require any specific hardware.
whenever game on my pc starts making noise, maybe fan noise.
after power cut my pc never starts again even after pressing switch on button.then i have to switch power off from main switch and boot pc again.
