I replaced my econobox mobo with a new mobo and now I'm stuck with a very annoying startup process. Every time I start up, it will perform a test on my memory and then ask me to "Choose my operating system." How do I make it so that it just automatically starts without the test and just lloads my OS? Btw, I have an intel celeron 2.8 with chaintech mpm800-3 mobo. Thanks in advance.
