Here's my setup: img.imgcake.com/halppngap.png
Running everything at stock settings.

In short, I'm seeing variations of these pictures here:

This was happening every few minutes at a time, regardless of whether I was gaming or not.

My monitor started doing this after I installed the drivers that were included with the card. I removed the drivers with Atiman Uninstaller 7.0.2, and updated to the Catalyst 12.11 drivers. This fixed it, until I shutdown my computer. Upon booting the next day, it happened again. As of now, my only solution is to restart my computer a few minutes after every startup, which seems to fix it until I shutdown again.

But, that's quite a nuisance, so I did a fresh install of windows, and installed the 12.11 drivers again. No problems, until I shutdown again. The bars are back, and it's getting on my nerves.

if you've reloaded drivers and windows, sounds like it could be a bad card.

When it happens, do you have to hard reset the PC? If so, your graphics card is faulty. I'd send it to warranty service.

Exactly which card is it?
If it's a factory overclocked version go into the Catalyst Control Centre, activate Overdrive in the 'performance' tab and set the clocks to 800 MHz core 1250MHz memory-Do n't forget to click 'accept' ;) .

Even if it is factory overclocked, it has to work on settings it came from the factory. If it doesn't, it means it's faulty.

Did I really have to make the point that obvious? .

Possible, but I haven't tried shutting down without the drivers yet. I'll try it out later.

Nope, just soft resets.

Pretty sure this one isn't overclocked. I'm at work right now so I can't try out these suggestions.

Could you explain soft resets? What happens, exactly?

I'm not entirely sure to be honest. But as of now, my "solution" no longer appears to be working. Haha.
I'm leaning on the possibility that my card is bad, or I'm just stupid. Installing drivers can't be hard, right?

Anyway, I went ahead and installed the 12.10 drivers instead, and had the same problem, so I removed all my drivers via http://www.overclock.net/t/988215/how-to-properly-uninstall-ati-amd-software-drivers-for-graphics-cards rather than Atiman Uninstaller, and am now hoping for some wizard-tier wisdom to help solve this.

Since you're reinstalled just about everything, it's unlikely to be software related now.
It is very likely the card is at fault but a little further digging is in order to be certain.
First, get into the BIOS and reset it to stock settings save and restart.
Now you have a leval playing field, download install and run Speedfan and GPUZ, just let the system idle with them ticking over and keep an eye on the temperaturers. Under idle, expect to see the CPU at less than 40C and the card under 50C.
If thats OK power down the system, remove the power lead then remove and reseat all the power leads, the memory chips and any addon cards, to make sure all the electrical connections are sound. Also check any chipset coolers are attached and held down correctly, one finger, gently does it!
