With all that rambling I have no freaking clue what you are trying to describe. It honestly sounds like you are trying to hook it up wrong or something. In particular, the motherboard hookups for video will not work (VGA/DVI/HDMI) in the presence of a dedicated video card. The company didn't disable it, that's pretty normal behavior. I'm sure there are ways to utilize both, but most motherboards just turn off the onboard automatically. Besides, if you have dedicated GPU, it's kinda stupid to use the onboard. Also, if the computer BEEPS once on startup, then it's probably fine hardware wise. If you've tried the dedicated video card's outputs on a monitor and you still get nothing, then it's possible that part is faulty, but at this point, it sounds like it's potentially an issue with the hookups.
BTW, what the hell is a 'very strong hdmi cable'.
A strong HDMI cable would be an expensive one i don't really care now we are sending the pc back for a refund the we will go to fry's electronics and build something way better for less. We also got an email back from them saying that it was fully functional and worked so it must have gotten damaged during shipping
other then that we have no clue on what actually happened. I also got some tip's from some people who know alot of stuff on building pc's they said that
a prebuilder web site is the worst choice from now on i am alway's going to build my own beside's i haven't done that before and i will learn more.
