new computer - no signal on monitor

post #1 of 7
Thread Starter 
so i got this new monitor its a 2233rz samsung syncmaster 3d monitor.
to go along with my brand new pc.

I set everything up and it starts up goes through POST by beeping once and stays idle running smoothly....except with nothing appearing on the screen. monitor is fine i read user manual and shows all indications that its in full working order.

i have no other monitor to test with.

what do i do?

i use a g800gtx card. and a dual link dvi-d cable. also tried it with a plain dvi cable.

Remove the GPU and try connecting the monitor to the onboard video to eliminate the GPU being the cause.

I had this problem when I first put my computer together. Have you made sure your GPU is fully powered?(double check the connectors are fitted properly) Could you try another PCI-E slot just encase it's broken? Attempt to use another graphics card or onboard graphics to see what the problem is?

k so i got it all working installed windows 7... then i shut it down and put everything inside the case and double checked everything. yet it doesn't work inside the case but works outside. its not the first time i try this. i double/triple checked everythingpower source psu switch all cables properly plugged in... there isn't much, just the 24 p main psu cable and 8p cpu power supplemental cable... & serial ata cable

is it because the motherboard is resting against/screwed to an alluminium backplate. should i put something in between?

Yeah, it's a grounding issue. Did you apply the standoffs to your motherboard?

Sounds like that's exactly the issue........... the case came with little brass"stand-offs", with a threaded post on one end, and female threads on the other............ it's function is to prevent the motherboard from shorting out against the case. As you surmised. take the motherboard out, screw in the stand-offs ( look at the motherboard ........ it has holes in it with metal reinforcements around them where you put the screws in) , and then attach the motherboard to the case by screwing it to those stand-offs.
