Dual Monitors Trouble Shoot

I currently use dual monitors while working. I had a slowing down issue and had to Force Shutdown by holding down the power button.
After I turned on my computer, one of monitors stopped working. Here's video card info:
Chipset Model: ATI Radeon HD 2600
PCIe Lane Width: x16
VRAM (Total): 256 MB
Vendor: ATI (0x1002)
Device ID: 0x9588
Revision ID: 0x0000
ROM Revision: 113-B1480A-252
EFI Driver Version: 01.00.252
Resolution: 1600 x 900 @ 60 Hz
Depth: 32-Bit Color
Core Image: Hardware Accelerated
Main Display: Yes
Quartz Extreme: Supported
Status: No Display Connected
Both monitors still work as I switched their DVI cables and the other would work respectively. The thing I noticed was when I unplugged the DVI of the non-working monitor and plugged it back in, the working monitor turned blue for a few seconds and goes back to normal.
Here's the list of things I tried:
• "Detect Displays"- slight choppiness of the mouse but nothing
• Reset SMC
• Reset PRAM
• Tried updating firmware but my computer wouldn't let me since it was unnecessary
• Opened physical unit and unseated the video card then re-seated
• Went to display options and tried several resolutions, still nothing
It seems my computer recognizes when I plug in the non-funct monitor but no signal is still found.
What else can I do besides replace my video card?

Check this out and see if it applies to you - depends on when you purchased your MP - but the warranty on the HD 2600 XT was extended to 3 years from date of purchase - link.
I think the XT was the default card.I cannot be held responsible for the things that come out of my mouth.
In the Windows world, most everything folks don't understand is called a virus.
