Problem with monitor
I am having a new problem, I disconnected a VGA cable from a Windows 7 computer to use on an XP computer, when I connected the VGA cable back to the Windows 7 computer it wouldn't recognize it. I did connect a DVI cable to the Windows 7 computer temporarily, now I have to use the DVI cable from my XP computer to use the Windows 7 computer. I need to know how to get the Windows 7 computer to recognize the VGA cable again. I know the cable is good it worked fine before disconnecting. I wanted to use it to connect the XP computer to my TV but it didn't work. I am tech savvy, but this is throwing me off. The Windows 7 computer stats are 7 Home 64 bit, 4 GB RAM, ATI Radeon HD 5570 graphics card. I have been searching for the answer for hours to no avail, any help would be greatly appreciated.
