In my experience
Dell = Built in obsolescence.
Still if tel can fix it he will be top 'pooter man
Well, all PCs have built-in obsolescence otherwise they'd have stopped selling them years ago... I don't think Dell is any worse than the rest...
This is worst-case scenario a hard drive failure - Dell wouldn't have even made the hard drive, it will be a standard off-the-shelf part like the CPU, memory, etc, etc.
It has been many years since companies like HP manufactured the entire system including the discs, memory and CPU!
