Please post exactly what equipment you are using and exactly what you are doing and exactly what the system is doing. Give us details.
Someone on the board will know whether your exact model of motherboard / BIOS and you are using should work together. And, since you didn't say anything about it, I have to ask you if you say the message on the monitor which tells you to hit a key to boot from the CD -- and, of course, if you are then hitting a key. If, on the other hand, you are getting past that properly but are seeing an error message about which specifies problems with devices or with files, we need to know that, too. Details!
