unpredictable crashing. Ideas?

I''m working on a program for my 4e3 entry, but it''s developed a tendency to halt the whole system every now and again when it''s left running. What happens is a pixel in the upper-left hand corner of the screen becomes white, and everything stops working except the mouse, then if I press a key, that stops working too, forcing me to do a hard reset (no ctrl-alt-deleting out of this one). As the problem occurs very infrequently, its very hard for me to track down exactly what''s causing the problem. Basically 20,000 odd lines of code are suspect (No, I''m not posting them). So, I was wondering if anyone else has experienced this and knows what caused it in their case. I''m slightly at a loss here. If it is a software problem, I reckon it''s got something to do with openGL calls. A video card problem would explain why the entire system crashes. To give an idea of what the graphics are doing, I''m using pretty big textures (512x512), vertex arrays, multitexturing, cube mapping (GL_TEXTURE_CUBE_MAP_EXT). My card is a geforce 2 Pro 64MB. I haven''t ruled out a hardware problem due to the residual humidity and temperature in the room I''m working. It does only seem to occur when it''s hot and muggy, although it is most of the time (it''s mid-summer here). The code is pretty CPU and GPU intensive, so it''s just about feasable that it''s overheating. Any ideas are appreciated ____________________________________________________________ www.elf-stone.com

Thanks for all the input. I''m now pretty sure now it is heat related. It''s been cool all day here, and it hasn''t crashed once. I may put 60cm fan in the min requirements...
