Hey,
I was wondering if anybody had a solution to this issue.

I just purchased an Asus EAH5450 graphics card - 1GB DDR3. It has HDMI, DVI and VGA on it. but I can't get any signal through DVI. Here's what happens:

I plugged it into the PCIe slot and turn it on. The fan spins up and the computer beeps to indicate it is all okay. I believe it gets into windows too, so no problems. The issue is, it won't display anything through DVI. It WILL, however, work with the VGA. The graphics card is a DVI-I output, and my cable/monitor is DVI-D so this may be the cause but it didn't seem likely to me.

Any help would be appreciated. The rest of the specs are below.

Motherboard: Asus M4A78LT-M LE
CPU: AMD Athlon II x2 3.0ghz
PSU: 320w
Hard disk: 1x 500gb SATA, 1x 60gb IDE
Graphics: 1GB DDR3 Asus EAH5450 PCI-express

afaik it doesn't matter DVD-I simply incorporates both analogue and digital. Check that your monitor (Menu) has the correct input selected.

Tested it on two different monitors and only VGA works, with scattered blocks of pixels on text mode. seems text mode on the BIOS screen should work in any case right? then Windows reboots immediately when beginning to boot

you are not connecting the hdmi to something at the same time as the DVI are you? typically these cards support one or the other, plus the vga, but not both.

also, try hooking up both a DVI and VGA monitor at the same time and see if you can enable the second monitor.

lastly, is there a reason you need to use the DVI instead of the VGA? depending on what youre doing, there may be no benefit to using the DVI

Nope, I don't have a HDMI monitor so I haven't tried that at all. I connected both (VGA & DVI) at the same time and the VGA monitor went on but not the DVI. But, the VGA monitor still has artifacts on the POST, BIOS and windows screens.

Just out of curiosity, what was your previous gfx card?

If it's Nvidia, you might have to get rid of any existing drivers + software and then reinstall the 5450.

My previous card was the motherboard (ASUS)'s onboard graphics was an ATI radeon HD 2100 chip and now I've put in the (also Asus) EAH5450 card, with the ATI radeon HD 5450 chip on it. I actually just flashed my bios to the latest version from the manufacturer's website and also cleared the EMOS (or CMOS? I forget) but I don't think the card was inserted until directly after I done that.

Another thing, I done it on another PC still with the onboard graphics and then went to bios settings for the GPU and the overclocker menu had all the options, up to 1024mb.. where I flashed mine and changed overclock menu from auto to manual and it only goes up to 512.. although my card is a 1024. is this a clue? I don't know what this is.

Hmm I take it you have already disabled the IGP within BIOS?

I could not find that option in my BIOS. It doesn't seem to have an option to disable the internal graphics. I did switch it from IGFX to GFX0 if that's the same effect

Yep GFX0 sets it to detect your card in the pci-x slot.

Might pay to uninstall your gfx card, remove card, reset bios to IGFX. 

Double check all is okay upon reboot.

Shutdown, reinstall card into pci-x slot, boot into bios and re-enable GFX0, plug in dvi connectors, boot to windows and see if it'll display anything.

It's a pity you haven't the use of another gfx card....

I've tried going back to my internal, booting, then coming back to the new graphics card. Didn't change anything.. does it sound like bad videoram to you? I've just contacted the person I purchased it from. I've spent 6 hours trying everything

Sounds like a bung card if you're getting artifacts.

Is the card new or 2nd hand?

Just an update.. I purchased a new graphics card by a different brand but using the same HD5450 chip and this one worked on my system, confirming it was the card not my system.
