So i am running 3 27" full hd asus monitors one with dvi its an older tn panel and 2 newer ones connect with displayport-mini displayport.

I had them in eyefinity setup for a while then some months ago one of the monitors got the no displayport signal so i swiched it to an hdmi.

Now some days ago when i got my lightpack and connected it i had to connect my tv to my pc too wich would not work as i already had dvi and hdmi connected i could not connect the tv with hdmi as it would concel out some of my monitors so i connected the monitor back with displayport and it worked again so idk what the problem was.

So now i run dp,dp,dvi,hdmi the hdmi one is for my tv and that i only have connected when i watch movies so its not always on its off most of the time.

But now to the real problem when i start my computer the computer itself turns on, the fans spin etc but my monitors wont turn on, they do not say no signal or anything its like they are on but they show no picture at all.

And my keyboard and mouse led wont turn on either so its like the pc turns on but does not really boot or anything its like you would start it without a motherboard with just a psu and fans.

After some restars the pc will boot up normaly and this problem only started after i have 2 of my screens connected with displayport, this should not change anything but still the pc have really big problems with starting up.

i have not yet tried to swich back to hdmi,dp,dvi as it worked before, and before it was dp problems too when it just did not find it and said no displayport signal and showed no picture as i did say earlier in this post.

So do anyone here have any idea what the problem would be, as i count myself as a pretty knowing guy with comp etc, but this one i cant figure out at all.
