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

You mentioned your using a DVI to VGA connector - is your LCD set to the right mode? Usually most LCDs give you the option to use your VGA, DVI, or HDMI mode if it has multiple connections. That could possibly be the "problem".

If that doesn't work or you already tried it, try this: Turn off computer completely, unplug power as well.

Unplug any wires to the card and take out the graphics card, reseat it. Make sure it is level with the PCI Express slot, and not inside at an angle. Make sure the 6 or 8 pin power connector is plugged into the graphics card. Then replug everything in and try it out again.

One more thing, why are you using a dvi to vga connector on an LCD? Doesn't the LCD have a DVI connection? If so that would give a much better/crisper picture using a straight DVI to DVI cable.

yea it works when i use the other cards, my friend got the 750w psu on a gud price thats why. is it possible that the vga to dvi adapter can cause the card to see no lcd and not put out signal?

idk why he didnt buy the dvi or hdmi cable for it so i just worked with what he had, is it possible that using the vga to dvi can cause the card not to power up and display on the lcd, i'm starting to think its a pcie 2.0 board vs 2.1 card issue. what do you think?

Ok a few more things you can try and by the way that 2.1 card should work fine even though the slot is 2.0 (it may need a BIOS update though):

Make sure your computer is shut down, unplug the cord from the wall or the PSU. Now take out the CMOS battery (it looks like a watch battery) and should be on the motherboard somewhere. Leave it out for approximately 5 minutes. Plug everything back in and try it out again...if that doesn't work....

If you have an older card you can use, try updating the BIOS of the motherboard first. After that - try putting the video card in again.

i've used vga, i've used vga to dvi adapter, i've used dvi and hdmi connections...i've learnt that the problem is with the board "pcie 2.0" trying to read the card "pcie 2.1" there should be a bios update for this issue but i can't find it.

i've used a compaq monitor with vga cable the monitor is fairly new and is hdmi compatible and also a new led asus 22" lcd monitor with dvi and then hdmi and still no output. the proble is with the board not seeing the card because it is pcie 2.1, i cannot find the bios update to fix this issue.
