Stuck with white screen

[kaisap112]

I've used No$GBA with No$Zoomer and it worked perfectly.
But today I open the emulator, load a ROM, and it gets stuck on a white screen (top and bottom). Nothing happens, the percentages are 100% and framerate goes from 5 to 0 in a second. White screen stays, restart, still white.

I tried loading other games (first I loaded Shin Megami Tensei: Devil Survivor, which worked just fine yesterday), but nothing loads. I re-downloaded the emulators, still getting white screens. Tried deleting .ini files, still nothing.

This is really bad, since I'm a Let's Player on Youtube and I need the emulator to work so I can continue my work.

I use a laptop with Windows 7. This came out of the blue and I swear I didn't do anything differently than I've done for the past year or so.

Please help!

Did you install any driver updates or the like? Do the games work with No$GBA alone?
Haven't encountered anything of the like, so I'm kinda brainstorming.
