A7N8X problems

i finally got my computer to boot up after i turned the hsf around the opposite way. The problem was the comp would bott then shut itself off in about 20 seconds. Now the problem is it says a media drive is in error, and I dont know what to do. I have a atlon 2100+ and it says it is running at a 1500+ also. And at startup it doesn't seem to recognize the ddr ram, it continues to have a "0" beside the words when i boot it up. It is a crucial 256 pc2100. It anyone has any ideas or solutions i would very much appreciate it. And any help with what to set the bios and jumpers at would also help.

THANK YOU FOR YOUR HELP, BUT ISN'T THE FSB SET TO 133 ON DEFAULT OR AM I WRONG? I CAN'T REMEMBER. AND DO YOU KNOW WHAT SOME OF THE OTHER SETTINGS SHOULD BE SET TO FOR OPTIMUM PERFORMANCE?? THANKS FOR YOUR HELP?

The fsb jumper must first be set correctly 266/333. Then in the bios you need to check your settings to make sure they are right.

Try the aggressive settings for the memory. If that works great. You can optimize more if you want.

DO YOU THINK THAT THERE MAY BE A PROBLEM WITH THE MEMORY I INSTALLED (CRUCIAL PC2100 256MB) OR SHOULD IT WORK ITSELF OUT? ALSO DO YOU KNOW WHY THERE WOULD BE A MEDIA ERROR? I JUST WENT AND BOUGHT SOME NEW ROUND CABLES FOR THE DRIVES...SO.
