Computers and electronics are very funny things and we all try to buy the best hardware available but it goes bad sometimes,
Motherboards, processors, RAM, PSU's, GPU's, all kinds of other stuff and its due to most of these things being made in factories.
But ever buy something that was noted to be bad or horrible and yet it still can preform?
I know I have, I owned an E machine and it was actually one of the best computers I worked with.
I have one of those Bestec power supplies that are notorious for failures and killing mother boards, yet the one I have has outlived my old HP computer and still works today.
I am sure I am not the only one who this has happened to, as sometimes a bad product can utterly surprise you.
