this important too? 7.
My system worked perfectly for almost a week but now it’s showing
symptoms of a low powered PSU, could it be possible my PSU is underpowered? 8.
How can I tell my PSU is underpowered? 9.

pushing the reset button. Why? 10. My
PSU has an input power rating of 115V/60Hz; can I use it with a 220V/50Hz power? 11.
When I turn on my system, the LED’s will come on for a second and then it

I wait for a couple of minutes or less, push the power on switch and then
LED’s will come on for a second and then off again.
