I get a black screen after I turn on my PC
Hi everyone!

When I turn on my PC I get a black screen and message that says my monitor doesn't have video input, but after I reset it, it works well.
I have this problem since I bought my new pc case, but i dont have any new hardware.

edit: I also have random fps lags when i play league of legends, but other games like CS:GO and Battlefield 3 runs smooth at fix 60fps

What GPU, Motherboard and PSU are you using? Some thoughts:
• Try to disable Onboard or integrated Video or switch it to PCIE in bios. Could be computer is trying to use Intel or AMD integrated graphics on your first boot.

Yep - closet to cpu.

Try wiggling the cable to see if its a problem. Can you replace the cable?

But you re-hooked up everything to get it in the case.

Check -

Your graphics card is locked into the top pcie slot.

The power supply connectors on the graphics card have been connected properly.

You've got the monitor cable running from the graphics card rather than the motherboard. And from the right port.

The monitor cable is done up properly both ends.

I checked the cable a few times, i think its ok, i assembled the hardware the same way as in the previous pc case, and i used the same cables.
I have 1sec screen freezes randomly when im playing league of legends, but everything else seems to work without problem(CS:GO, Battlefield 3, Video players, Internet browser).
