Hello, 3 months ago i purchased a asus cm1745 desktop from best buy and just started upgrading it. I encounter a problem though when I installed a new graphics card which was a sapphire DualX OC 1gb 7790 (used to be 7470) it displayed no picture it did not even show the display for booting. I said "Man I screwed up!" Well after a bit of researching I discovered I needed a better power supply (500w). I went out and bought myself a psu (700w) and still it did not show an image, but when i reinstalled my Hd Radeon 7470 it worked perfectly fine and no problem?
The fans and everything seem to be working but i'm getting no display when using 7790.
I uninstalled the drivers, I tried the hdmi from motherboard and everything yet nothing works. The gpu fits into the PCi slot and I have the card directly connected to the psu. I have no idea if its defective. I purchased it from new egg.
My computer also has integrated graphics yet i dont know if that could be the problem.
