Monitor no signal (cannot detect vga/dvi)
Two days ago, I unplugged all of my cables (monitor, mouse, keyboard, ethernet, etc) so I could move my table around. When I re-plugged my cables in, my monitor couldn't detect VGA/DVI for some reason, and went to sleep. I thought my GPU was dead, but it turns out to be fine. After countless reboots, and using onboard, and re-installing the gpu, I was able to get a connection.
My question is, does anyone know what causes the monitor to fail to detect a signal?

Does your LCD have 2 inputs? DVI and VGA? Have you tried both? Do you have another computer or laptop that you could try connecting to the LCD?

You may have bent some pins on your cable when you moved it around.
Check the male connectors on your cable to make sure nothing's bent/missing!

Yup, I plugged it into both inputs and they both didn't work (although it works now)
When I was having the problem, I plugged it into my laptop and it worked fine without any issues.

I've had this problem before too several times in the past...
Did you test your monitor with another computer to see if it's really the monitor that's faulty?
For me, I eventually fixed it by hooking up my monitor with another computer.
Then I went into safe mode and did a system restore.
I'm not sure why that fixed it, but my suspicion was that some how, my monitor/gpu setting got set to
a resolution out of my monitor range, so now it's "stuck" at those ranges, and you can't revert them back since your monitor isn't giving a signal.
Not even sure how that could happen by just unplugging and replugging in a monitor, but that's just my theory anyway.

I would say it is, because during first start up the fans on my graphics card was still spinning.

Yup, I plugged my monitor into my laptop and it worked instantly with no issues. I tried both slots of the graphics card, and still got no signal. I re-installed the GPU and still no luck.
I went onto onboard and it was saying how "resolution is out of range" 10 seconds later, my monitor would go to sleep. I went into safe mode so it would stop going to sleep, and adjusted my resolution to a lower one.
Then going back into normal mode, my resolution was basically messed up. I did couple of reboots, and re-installed GPU/blew out dust in the slot just in case, and tried re-plugging my monitor cable to my GPU and it suddenly worked lol.

That doesn't mean much, is it bolted/clamped down in some way?

Yup, my 5770 takes up two spots in the back of the case, and both of the screws were screwed in.
