I have recently rebuilt my rig (new motherboard & PSU), and have encountered a strange problem - when I have my graphics card plugged in, the system won't power on (there are LEDs lit on the motherboard, but fans don't spin at all, just no activation).
If I remove the card, the system powers on.
I actually have 2 different cards (same model), and neither of them allow the system to power up when plugged in.
I initially thought this was some problem with the mobo being brand new ad trying to use onboard graphics or something, but I then tried a really old card, and hey presto - it powered up!
So, why would my newer cards prevent the system from turning on? I could understand if there was some problem with the cards and they didn't display right after the system powered on, but it makes no sense that they would just stop the system from activating.
Only thing different with the old card is that it's a single slot, where the 7850s are double slot.
Any help appreciated!
My mobo model is Asus P8Z77-m Pro, and the card I am using is a VTX Radeon HD 7850. They are going into a NZXT Vulcan case, with a Corsair GS800 PSU, core i5 processor and 2 sticks of 4GB DDR3 (1333Mhz).
