Cat (1)/Computer(0)

[jdoggrr]

So I was happily playing Warhammer when the cat walked behind the monitor and *POOF!* no graphics signal. I waited for a while, and then hard-rebooted. Now I get a "Input signal out of range" error. I have:

• fiddled with/replaced the cables
• swapped the monitor
• tried to boot in safe mode (didn't work)
• replaced graphics card
• had the cat walk backwards behind the monitor

Nothing's worked.
So, do I get rid of the cat? Can you get my computer back for me?

Thanks!
