Hi, I'm having some trouble with my asus radeon hd 7770 i've set it up in my pc connected the power and i get no signal on my monitor i dont see bios or anything.
system specs:
Motherboard- Asus P6t deluxe v2
CPU- intel Core I7 965 3.2ghz
PSU - 1200W turbo cool
Memory - 6gb 1033mhz patriot ram
OS - Linux Mint 17 Qiana and Windows 8.1 and windows 10 technical preview
More info:
so ive set up the card ive made sure its in correctly but still dont get a signal im using the dvi on the card but have also tried with an hdmi and still no signal. i did get it to boot once while fooling with it but once i installed drivers and everything i started up a game and it immediately crashed on windows 8.1. upon reboot it came back to no signal ive contacted asus for an rma but they have horrible customer service and its been about a week now and still waiting on the forms for a cross ship they keep telling me 24 more hours but it seems like it never comes. so i just wanted to post on here and see if there may be another underlying problem i am able to put my old nvidia geforce gtx 275 in along with the asus hd 7770 and use the nvidia for display and windows recognizes the hd 7770 along with the 275 anyone have any clue as to what this might be? i didnt know if there may be some sort of incompatibility issue that i am unaware of.

I don't have another pc to try it in and I've tested the cables but I can't tell why it would work in another pc when I know my pci slots are working and I've tried all 3 of them. My power supply is we ll over what is needed to power the card. I guess I'm still waiting for asus to figure out the rma process thanks
