When I got this and first plugged it in, the fan was very noisy.  It sounded kind of like very angry and big bees.  The sound would come and go.  The computer worked fine though, so I did not think to return it.  I just used it for working from home.  Then, after six months,  it quit powering on when I would hit the power button.  At first, unplugging the power cord and plugging it in again would solve the issue, but now that does nothing.  I have tried different power cords and outlets, but none of that solves the problem.  I am thinking that the power supply might be dead and causing the problems.  That would mean the computer came with a power supply only good for 6 months.  I thought I got a good value until I realized that this thing would barely last.  I think it was listed as renewed, and I only saw a 90 day return policy.  Because of that, I am out of luck for a return.  I would have recommended this before, but the power problem and bad warranty ruined things for me.
