so i recently bought a Sapphire Radeon HD 7770 GHZ OC Ed 1GB DDR5 PCIe 3.

i go to install it and it wont send any signal to the dvi monitor. i check to see if it will work on my brothers rig. it does. what should i do to make it work? new to this stuff i have to dump some bios stuff or uninstall video drivers? ive seen a bunch of different answers to the problem im having but im not sure which to try and frankly im tired of switching my 8800gt in and out with the new 7770 while trying to fix the problem. about 4 hours problem solving time and still nothing....

well if the card works in another system, that means the card is good.

if the card is seated properly and has the power cable connected, i would lean towards this having something to do with the nvidia chipset.

is there possibly a bios update available for your motherboard?

download the latest amd drivers.

uninstall the nvidia drivers ( add/remove programs should be sufficient )

shut down. remove nvidia card install amd card. reboot. let windows find card. then install the drivers you downloaded.

should work...............

I'm thinking it's something with a poor PSU and it can't even supply enough for the GPU.

psu is 750w corsair i doubt its that. i uninstalled my old nvidia drivers, installed the latest MOBO bios and it still wont work... sigh. i also installed the drivers for the 7770 before i put the 7770 in maybe i need to uninstall those too? sighhhh i want to fix this already.

after doing some research, your motherboard has issues detecting ati/amd cards. theres a few people out there that got the system to post, after waiting for 5+ minutes. try to power the system on, and give it 5-10 mins and see what happens.

this has nothing to do with drivers, cables, or power supply. this is a compatibility issue between your gpu and your chipset.

so youre saying "shut my pc off for 5 minutes.> install the 7770.> turn power on> wait 10 minutes?"

i would find a cheap replacement motherboard. if you do some searching, it seems many people have trouble with that chipset and amd gpu's
