I must update as I just got the tower back from the computer repair shop. It seems the motherboard was trash.  I have had this computer less than a month. Downloaded very little. I thought it was an operating system issue, however the computer guy said he was surprised the machine even turned on.It must have been refurbished by a middle school computer class. Will not run half the pre-installed programs. Will not install or update java. One of the monitors likes to randomly shut off. So far the brand new keyboard and mouse that came with it seems ro be the only worth while purchase but definitely not at this price.
