First of all, my PC specs (in short)
AMD 2000+
1 gig ram
Well, Ive been working on this Source map the last week and i always test small parts of the map out all the time, checking in the compile works as it should. Then suddenly ctsrad/vrad (I checked with both) suddenly crashed my computer and made it restart when it was about 99% done. This ofcourse was a problem i had to solve and i thought it had to do with the map. I had just made round towers and a mountin almost coming out of the first tower (so the tower was embedded into the cliffwall). So i figured the cliffwall had to do it, since the compile worked good when i compiled just the towers.
But that wasnt it, because when i compiled the cliffwall alone, it worked just finet oo. But putting them together on the map crashed my computer. Even if i had them separeted (no brushes touching eachother).
Well, then i thought it might be that i had fucked up somewhere and the easiest way was to just rebuild the entire thing. Afterall it wasnt that much work. And i compiled almost every hour just to catch the problem early if it was to rise again. But then suddenly it appeared again, out of the blue. But now there was nothing that was wrong and when i opened up an old build of the map that I had compiled before, it too restarted my computer.
Well, I've figured out what it was now, and its pretty funny (atleast to me now, since ive wasted my entire weekend with this problem). Im just going to let you guys try and guess what the problem is. My roomate was actually telling me from the beginning what the problem could have been, and he turned out to be correct. I was just stupid not to listen.
So... GUESS AWAY!
