So i got the system up and running finally but its still not working right. My specs are on my signature. When i load up the computer it loads everything and tells me the masters and slave and how much ram and everything i have on my comp but then i stops at Cmos Check Sum Bad. And i asks me to load the bios so i do and its only reading my cpu at 1.59 GHZ when it should be running at 2.8 GHZ. The mobo LED is giving me code 87 and i have no idea what that means but back when it was working thats not what the code on it was. Anyone have an idea as to whats going on?
