Hi,

I just moved my computer into a new case (so no real hardware changes), but now I'm getting no signal when I connect a display.
The display registers that something is connected (different error message), but no signal is received whatsoever.
I have tried connecting through VGA (through a DVI adapter) and HDMI.
The motherboard doesn't sound any error codes (although it doesn't when there's no graphics card in at all either).
I have tried removing the graphics card completely (an ASUS GTX 295) and putting it back in, and I have tried moving it to a different PCI slot.
I have tried connecting a USB keyboard and mashing all buttons, but the keyboard doesn't seem to connect at all (this could be interesting, since a PS/2 keyboard might work?).
Slowly running out of ideas, does anyone have an idea what could be causing this? :)

Thanks in advance,
- Johannes

I have taken out and put back in anything that could be related to the display, but no dice. Everything looks as if it runs fine inside the case, all fans are running, everything is lit, no error beeps, just no signal to the display.
