This is exactly why I recommend ( & have built quite the customer base in the process) against buying OEM PC's like Dell or Gateway. The parts in those PC's are supplied by the lowest bidder, so you know it's not going to be terribly reliable...

"OEM manufactures are starting to get really bad about cutting corners and then selling their machines overpriced. This creates many problems for PC Technicians- although we can thank OEMs for keeping us in business - because we end up being the ones to break the bad news to the end users."
