This has been happening for a while now, but only recently has it become a problem. I can no longer run my laptop in normal mode, and have been reduced to using safe mode. Attached is a picture of what the screen looks like when it freezes.

The screen isn't broken, or the pixelation would go away. The crashes don't register in BlueScreenView, either.

Please help me if you can.

Did you try to reinstall your video driver?

Hello again, Mr. Broni. ^_^

No, I've not tried that. Would I be able to do so from Safe Mode?

I've never had to reinstall my video driver before. I'm nervous about doing it; will it cause my screen to blank out? After all, I'd assume my video driver is what allows me to see my screen.

Yes, but you still will be able to see your screen, because Windows will load its own generic video driver.
For instance, this is exactly what happens in Safe Mode.
In Safe Mode, you're using Windows generic video driver, not your original driver.
That's why my first suspicion is a bad video driver.

Should I download straight from ATI/AMD's site, or from HP? They show different files.

Your computer manuafacturer is always the very first place to go, so if it's HP, you go to HP.

After I uninstalled the driver, and tried to install again, I got the error message "failed to load detection driver".

Alright, got it reinstalled. It's too soon to tell if it'll happen again, but for now I'm not being forced to use safe mode. Thanks, Broni!
