Hi,
I just bought a new GT 640 2gig Graphics card for my system but after installing the card there is no display via the DVI-I port (using an DVI 2 VGA adaptor). There is a beep from the motherboard so I presume the board is is detecting the card ok but could the problem be the DVI port? it has a mini HMDI port but I do not have a suitable cable for this, trying to source one but I do not want to waste money on a new cable if the problem could be something else. The card specs is asking for a minimal PSU rating of 350watts with 20 amps and the +12v rail, I have a psu rating of 450watts but only 15amps on the +12v rail, could this be the cause?
