I am at a career center, and we have UE3 installed on our computers. It was a free package with only basic UT3 assets. However, the two computers that have it correctly installed recently just stop working. The screen turns one solid color and will not work. The only option is to force the computer to shut down. Trying to run the editor seems to crash the computer immediately, shortly after it opens. However, this problem occurs regardless of whether or not the computers start the program or not. They now crash regardless of whether or not UDK3 was running or not. The timing seems random, but seems to be getting more frequent. They are unusable now, and as they are University loaned computers, we cannot roll them back. My IT teacher thinks it may not be UDK however, it makes sense as only the computers with it correctly installed have this problem. I am at a complete loss as to what to do. Please, for the love of god, help.
You might consider posting this on UDK forum section as you more likely get reponce there:
