So, earlier today, I was loafing around on Steam when my computer suddenly locked up. I decided to manually restart the machine, but it constantly displayed "Cable Not Connected" when I started it back up. I took the cover off and wiped some of the dust off of the graphics card (a GTX 950, two-fan model) and made sure all the fans were working properly and not jammed. It still displayed "Cable Not Connected", but after a lengthy pause it finally started back up, though it seemed to have already passed the graphics card's booting screen and the "loading" screen. I had to manually change my resolution back to 1280x800p, but it seems to work now. The computer sounds perfectly fine.

What I'm worried about is that whenever I try to boot up GZDoom, it seems to be "transparent". In other words, I'm seeing the desktop, but I know GZDoom's open, and I can even blindly navigate the menu, start a new game, shoot, etc. etc. I really don't know what's up with it, especially since other games (such as Quake II on Steam, and OpenRA) work just fine for me.

Just for reference, my computer's a Dell Inspiron with a 3847 CPU, running Windows 8, with a PNY-made GTX 950, two-fan model. It's also got a Corsair CX430 power supply. Everything else is stock.

Does anyone know what's wrong and how to fix it?

Do you have the same issue with ZDoom? For Quake II, are you running it in GL mode or software mode?

It's likely a hardware problem given the issue you've had.

Seconded what Gez said. It sounds like your GPU quit, or your drivers broke, but for whatever reason the rest of your computer is fine.
