I just installed a new Biostar motherboard and processor. It is a Biostar N68S3+, AMD Athlon II X3 455 Processor, and 4 gb RAM. Now it will not boot up. I was a little disappointed that it did not have two IDE connectors, as I have an older DVD drive. It goes to a black screen with startup choices; start windows normally, last good configuration, safe mode, etc. I have tried all, and it posts then goes back to this screen. In safe mode, it appears to load some of the drivers, but starts over. Everything booted fine with my old mobo, but it kept shutting down. Any help will be greatly appreciated. What am I missing?
