Viewsonic vx2835wm 28in LCD "bright blue screen" (not BSOD )

I've replaced my graphics card recently-had an MSI NX8800GTX 768mb which stopped working-dont know why. (I have NEVER overclocked either of these cards). I bought a BFG 9800 GT 1gb and now about 2 months later I had been watching movies through my PC and shuty PC off for the night. The next day...nothing. Now by this I mean my Viewsonic LCD just has this bright blue screen (not the BSOD ). I dont even get the "no signal" message one normally gets when the monitor is on but the PC is not. I can have the monitor on , then power up the PC and there is NO CHANGE at all. Now I can HEAR my PC booting up-I can even tell when my login screen has appeared and I can LOGIN ! I just dont get any activity on my LCD. This LCD has 5 connectors in back. The : D-Sub, AV , S-Video , YPbPr ,and HDMI . I use the HDMI for my PC and the YPbPr is hooked to my HD Cable box. The TV connector works fine. I tried to hook my PC using a DVI to D-Sub and got no response with this either. Honestly , I dont know which is most likely , the graphics card or the LCD input connection. Has anyone have any experience with trouble on their Viewsonic 28in LCD monitor ? I havent owned the monitor a year yet and the graphics card is only about 2 months old.What would cause a graphics card to die-bad motherboard ? I will entertain any and all ideas and I thank you all for your time. My "configuration" has all my specs.
