Have had this for a couple years.  Blue screen of death several times a day since new.  We had already purchased and loaded all of our various software packages - about a day of work to get everything in and updated.  Wiped it clean to see if it would still BSOD and it does right out of the box.  Too late to return so we re-loaded everything (another day) and just live with it.  I can finally afford a new PC so this one will be sent to the landfill, not recycled for some poor unlucky soul to be taken advantage of.  The seller knows these PC's are no good, they should not be selling them.  I would avoid the seller as well.
