I bought this computer in December then suddenly in August it stopped working. We ruled out the power supply and know that it’s either the processor or motherboard. I contacted cyberpower the day it stopped working and was told to ship it to them, at my expense, which was fine. I have not been able to find the correct shipping supplies they requested *anywhere* and they told me that they would not send me the shipping material required for their computer, even though I wasn’t able to find it anywhere myself—basically they told me to just figure it out. So now we have a computer that does not work, but is under warranty, with no way to ship it. Now we have to buy another computer—definitely will not be from this company.
