[Help]Hangs at Flag bootscreen, then reboots if keys are pressed

[unterdude]

Hey, I'm having a pretty serious problem on my main rig, so this is kinda urgent. Last night, I removed a HDD I wasn't using, it was IDE, and then restarted my computer. It would POST fine, and then go further into the screen where normally it would show a Windows flag and a green progress bar, but I have a custom boot screen.

There, it would kinda just "clip", meaning the bottom half of the image would become all distorted. From here, if I pressed ALT+F4, CTRL+ALT+DELETE, or Escape, my computer would restart, but pressing any other key, it would just hang at the boot screen.

I tried starting in safe mode, but it goes through the bootscreen too and does the same thing.

Right now, I am trying to figure out if the boot screen got corrupted somehow or if it's something else that's wrong with my computer. I've been using it fine for the past 3 months, it is the one that came with XPize, a program used to "make windows pretty"

Thanks for all your help guys!

Possible driver problem? Does it work again if you put the HDD back in?

Does the Command Prompt still work?
