Complaint Review: Hewlett-Packard Development Ltd.

I purchased a HP Pavilion p6703w Desktop PC on 2/25/11.  On 5/19/11, using factory installed HP diagnostic software, the computer informed me that the video was not working properly.  On 5/19/11, I contacted the HP Tech Support (as instructed by the computer).  They verified that the video HARDWARE was faulty, and instrcuted me to send it to HP for repair.  HP sent the computer back to me, arriving on 6/1/11.  When I turned it on, the HP diagnostic software informed me that ALL the hardware tests had failed (not just the video).  I again contacted the HP Tech Support, who verified that the computer was not working due to "unknown hardware failure".  The HP Tech Support referred my case (Customer Service Account # FTG990-01) to the HP Case Resolution Department.  On 6/2/11, that case worker called me.  He informed me that NO actual repair work had actually been done (only a reloading of the factory-spec programs - NO attempt to fix OR repair ANY faulty hardware!).  He informed me that NO replacement/refund would be authorized due to the warranty.  I told him I never was issued any written warrant (not in the delivery box, at the time of purchase or delivery).  He instructed me to AGAIN send the comnputer to HP for repair!?!  When I diagreed with this, he told me to return it to where I had bought it for a replacement or a refund.  I am now stuck with a $600 computer (fully paid for), and asked to believe it will be repaired by HP (who has already lied about trying to fix it the first time it was sent to them for repairs - remember, they diagnosed a faulty hardware problem, and only reloaded software which would not fix broken hardware!).  They also refuse to simply replace the broken computer with a new one (same make and model), and will not consider a refund under ANY circumstances!  Also, HP corporate will make NO attempt to resolve this problem (yes, I tried talking to them, too!)!  So, I have spent $600 for a broken computer that the manufacturer wil not fix, replace, or refund!
