http://pcpartpicker.com/p/zCbmnQ Assembled this computer about 3-4 weeks ago and now the monitor doesnt get a signal from the computer. I have tried just powering it on with nothing but the mobo, PS, CPU, CPU cooler with the monitor plugged into the HDMI slot on the mobo got nothing. I've never managed to get my monitor to detect the hdmi on the mobo since i first built it, i managed to get my display to work by running the d-sub cable that came with my monitor hooked up to the graphics card. Now thats not working anymore I tried booting with 1 stick of ram and switched when that didnt work. Pulled out the battery for a few mins then tried booting up no display. Was working pretty good till it went into windows sleep mode and stayed stucked like that with sound still going. Tried to restart and now wont display anything, any solutions? Im thinking mobo faulty

gpu is short for my graphics card right? If so then yes tried both mobo and graphics card to get a signal to the monitor. The graphics card was working with the d-sub cable for a couple of weeks but not anymore.
