Connected this pc to just a keyboard & monitor the day yesterday (hours after arrival). Immediately upon pressing power the system tried to turn on, the fan started blowing and Immediately cut and the system beeped. If you don't press & hold the power button again, it continues this cycle of attempting to start, fan starts to blow, system beeps and everything stops... over... and... over... and over.Troubleshooting- 2 Computer Information Systems professionals in the house. We determined the issue to likely be either a faulty power source or card. Either way, upon reaching out to the support number and stepping through their basics they said we'd be able to return it for a refund.I'm always on the fence about purchasing refurbished anything for this reason. After reading the reviews however,  I thought "Why not?? I was prepared for all the little issues people reported, but am definitely disappointed by this experience.
