graphics card hd7770 & black monitor

LouTurk · Mar 24, 2014

I've installed asus Hd 7770 graphics card. got VGA to DVI connector for monitor and Plugged 6-pin PCIe into rear of GC for power. My monitor remains black. WHY, Oh WHY? Can anyone ed me?

What power supply and what kind of connector? Does you monitor only support VGA?

Make sure you are plugging into DVI-I connector on the card, many have two connectors and one can be DVI-D. As well was previous GPU deleted properly in Device manager before swap?

Antec TruePower Trio 650W (recently upgraded). Monitor is 10 years or older and it has a black cord with blue bulky adapter with 15-pins staggered in three rows (is this called a VGA or a DVI?). I got the vga to dvi connector from RadioShack who told me that the female side (15-pins staggered in 3 rows) and the other end that goes to the graphics card could have 4-pins on the left and 8-pins on the right side with a horizontal bar and work just fine. I only mention that because I thought it was supposed to have 24-pins lined-up in three rows with a horizontal bar to the right inside the adapter. My apologies for not knowing the terms for everything I'm describing.

The blue bulky thingy is the VGA and the one on your PC is DVI. Now, does the monitor work with other PCs and can you try to connect your PC to a television through HDMI to verify whether or not your GPU is working as it should?

No, I'm not able to connect to a TV. And I did try to connect to another monitor and it was black as well. I just don't know How to tell my computer (asus p5gc-ms/1333 mobo) to recognize the new Graphics card. No I have not deleted GPU from device manager (don't know how to).

What motherboard/CPU do you have and what was you previous GPU?

I don't know what a GPU is...However, I did previously have a Logisys 350W CPU that could not support the HD7770 graphics card. MOBO is asus p5gc-ms/1333 to which I also added 2 x 2gb of ram.

GPU=Graphics card (Google is you best friend)
So there are a few things we can try:
1. Did you previously have a graphics card or was your display connected to your motherboard?
If it was in your motherboard, try connecting the display back to the mobo and see if you get an image. If you do get one, you must disable the integrated graphics of your CPU. Refer to these for instructions:

2. Get a DVI cable that matches the one in your monitor:

Use this cable to connect your monitor to the hd7770.

I've never used a Graphics card before so, I guess it has always been connected to my mobo. And only when I plug in the 6-pin power adapter to the asus graphics card does the screen go black. I had to dissconnect the Graphics Card just to communicate with you (I only own one computer). I've been investigating the different VGA to DVI connectors and there are many. I'm not sure I've got the correct one. VGA side is compatible but the DVI is strange...It's a 12 +1 (not 5) like it should be. What I'm saying is that I can't find an example of my DVI side (12 pins and the horizontal bar minus the pins above and below). I wonder if I bought a defective one and RadioShack didn't even know it.

So is your display cable connected to the graphics card? Because it needs to be in order for it to work.

Yes, it was. When all is connected and I am using the VGA to DVI (male analog) adapter and the 6-pin PCI-e power cable is plugged into the GPU (graphics card), I get a black screen. I can only use my monitor if I unplug everything and put it back to the way it was. I can't use my GPU bacause I don't know how to tell my computer to pay attention to it.

Try the methods I suggested before (Go to BIOS and turn off your integrated graphics). Can you also post an image of your cables/adapters so i can get a better picture of what we're dealing with?

I'm going to asus.com to download latest BIOS file for my mobo and rename it by saving it to a flash drive. I'm supposed to restart my system and immediately press <Alt> + <F2> during POST (I have no idea what a "post" is). Insert thumb drive with new and imporved BIOS and update via EZ Flash. Does any of this sound close to being right? I'll post pics later, once I get my BIOS updated. Thanks for helping me this far.

POST = power on self test
It usually shows a OEM Or motherboard logo and happens on first powerup

My Mob is an Asus P5GC-mx/1333 and on the board it is stamped Revision 3.04. My previous GPU was my motherboard. I've never owned one. I took the Tower to a local computer repair shop and they booted it up in a matter of seconds. And they determined that the Asus HD7770 has a glitch (4 - 1 inch vertical lines running from the top to the bottom of the screen) in it because no matter what monitor or VGI cable I use. I confessed to them that I couldn't even get it to boot up. So, now I've got these lime green vertical lines. Looks real nice! Trying to contact the e-bay seller and he's playing coy.

Ebay?
That's why you should be leary about buying things like that on eBay
