When I purchased this computer, I paid extra for a Tower with HDMI.  However, when the computer arrived, instead of having a HDMI port installed in the computer, it came with an HDMI extension cord.  I had also just purchased a brand new HP 25f monitor.  I tried for several days to get the computer to work with my new monitor but, no matter what I did, I was unable to get the monitor to work with the computer.  So, I returned it and asked that the seller send me a new computer.  At the time, I just thought it was one of those things.When the new computer arrived, I had no problem getting it to work with my new monitor.  I installed all of my software & thought I was in business.  However, no more than a week later, the computer perpetually rebooted without ever opening Windows.  It would not even recognize the Windows disc (thinking I could fix the reboot problem by reformatting & reinstalling Windows).  No matter what I did, it was a total bust & I went to Best Buy and bought a new computer.Recently, a friend of mine who claims to be a computer expert, said he could fix it.  He disconnected the hard drive, the DVD drive an d 3 memory sticks.  It still kept rebooting.  Then he moved the memory stick and reconnected everything & he was able to boot into Windows.  He then tried to figure out why the hard drive keeps trashing about.  So, he updated to v. 1803 & replaced the Win7 overlay.  He thinks the computer is running too slowly.  And, get this, the reboot problem started again.  So, my friend replaced the power supply & he was able to reboot into Windows against.  However, he is still trying to fix the other problems.So, in sum, the computer was a total bust.  It didn't do anything that was promised in the ad. It was a horrible computer and horrible purchase!
