Black screen after putting in new ram.

[dart1194]

So i just got some new sticks of ram(g skill 4gb 1600 ddr3 and i get a black screen at start up. No keyboard light. Mobo lights are on and no way to get into bios. Went back to my previous sticks and i get the same thing now. I have a gigabyte ga-ex58-ud3r mobo, brand new nvidia 580 gtx, 800 watt power and a intel i7 quad core 2.67ghz I have a feeling that it doesn't support 1600 but i don't know why it wont work with my old sticks now. I've taken them out before and had no problems. I've tried switching them around, just one at a time and get nothing. Also i get no beeping just a black screen.

Bump

do the simple things first, make sure you didnt bump a power connection or the vid card. Its almost always something lose that causes these things. Another thing is try to clear the bios/cmos.
