HD5770 No Display ~help!~

[Dshaznet]

hi guys,

i've setup a desktop for my friend with an asus p5q-e mobo & hd5770 grafix card all being powered by corsair tx750 psu but when i turn the computer on nothing come's up on the lcd (dvi to vga connection) but the desktop post's and boots right into windows. when ever i try other cards they all work and the lcd will come up but its just this hd5770 card. the strange thing is that when i try this card in another comouter it worked just fine. any suggestions?

pic of setup:

sorry for the poor quality pic i just took it with my bb

It could be a power delivery issue with your MB and that specific card and it may also be related to your PSU. Sooner or later, something will probably fail all-round

i had a similar issue and the way i am finding out is sending my MB to Gigabyte.

yup the other slots wer tried

well its definately not a power issue...i found out the problem but idk if any1 know's how to solve it, the asus board i have has a pcie 2.0 slot that should be able to run every pcie 2.1 card on the market however this hd5770 is not back stepping to 2.0 nor is my board recognizing the card being a 2.1...i was told that there should be a bios update to fix this issue but i cannot find it so until then i'm screwed.
