Just had the exact problem this week.

Mine turned out to be the power supply just as was suggested to you.

As I was told, OEM's generally use cheap power supplies.

They are cheap enough and relatively to replace. It also gives you a good
change to upgrade the wattage as I did going from 250 to 480.

Good luck.
