Blank Screen + Cursor At Startup / Pavilion g4-2149se Notebook

Hi there! 

As stated, I have an HP Pavilion g4-2149se Notebook running Windows 7.

For the past 2 weeks almost, whenever I start my computer, before getting the Windows welcome screen, I get a lingering blank screen with a cursor. Then, it'll finally get to the welcome screen, but before it loads my desktop, I'll get another lingering blank screen with a cursor. Honestly, I'm grateful that my computer is still starting up at all... But is there any way to fix the lingering blank screens? It's making me nervous.

I've looked around the web for a solution for days, and anything I could find I've tried, but nothing has worked. I uninstalled all recent Windows updates, hoping one of them had went wrong, but it didn't help the situation. I scanned for virus' and malware and found nothing. I've only downloaded one program since I noticed the problem began (4K Video Downloader), though the program doesn't seem to be a problem for anybody else. 

Anybody have any idea how I could possibly fix this or something I've maybe missed? Any help is appreciated!
