Recently I purchased an MSI GeForce GTX 660 for Christmas. I placed it inside the computer, exchanging it with a GT 630. Everything is plugged in correctly, etc. I turn the computer on, and I receive the message: "no signal." So, I did some lurking. I've updated the BIOS (flash and all, whatever), turned off Windows 8 Secure Boot, upgraded the power supply to 630 Watts, disabled the drivers for the GT 630 and uninstalled it, and still nothing works. The computer boots up, but no signal is received. I even placed the 630 back in, and everything works normally.
I've spent all day attempting to get it fixed, but of course, none of the suggestions work.. I'm ready to launch the video card into the road. HELP ME!
*P.S: All of the specs for the computer meet the GTX 660's requirements.
*P.S.S: I've viewed another post on this forum before I created this thread, nothing there worked either.
