okay thanks and it is probably because of my motherboard. It's a PC a built myself from scratch.
This has almost for certain nothing to do with your problem. Please describe exactly the steps you did, the result you expeced and what happened instead. Your Gamesetudio version is of help too. How did you name the texture?
4 GB ram(3.12 usable) <--- I have no clue why it says that
Because you have a 32 bit operating system. Although you have physically 4 gigabytes of RAM available the operating system is not able to adress the whole space.
