What power supply and what kind of connector? Does you monitor only support VGA?[/quotems
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. I just turned the monitor around and it does have a DVI plug.
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.
