CAn't write this on our Dell since it's DOA. Let me preface this by saying ALL my parts and hardware came straight from DELL. And yet (1) THREE separate times, we had to replace our power supply when it stopped functioning, all three times giving the same error message saying the problem is that I need to use DELL parts. Also (2) Even though the computer supposedly had Windows XP (that's what it said ON the computer), some error messages, including my "black screen of death" messages, were about NT windows, not XP. Several years ago, I saw a news report about companies selling electronics with old parts, and selling them as "new" machines. I wonder if Dell has sold any computers as "new" when some of the parts are refurbished and not even from Dell computers? It just seems like I have had a slapped-together computer made of a hodgepodge of parts. Has anyone else ever experienced this?
