I just built a computer yesterday. It has an ECS L4VXA2/Pentium 4 processor, 2 512mb sticks of ram, a Radeon9600 graphics card,and Pheonix bios. When I turn the computer on the first time, the computer does it normal thing of checking the ram and all that. After it finds the hard drive, DVD drive, and CDRW, it gives me a message that says "CMOS checksum error - Defaults loaded Warning! CPU has been changed or CPU Ratio changed fail. Please re-enter CPU settings in the CMOS setup and remember to save before quit!" I pressed F1 and proceeded to install winXP and it worked fine until it got to the point where winXP automatically restarts the computer. Everytime the computer is reset, there are 4 seconds of silence followed by an 8 second beep and it keeps repeating, and the monitor never turns on. If I reset the bios using the jumpers, the computer will finally start up and give me the same CMOS checksum error as the beginning. Because I have never built a computer before, I had someone that builds computers in his spare time look at the computer/bios. He put the settings on what he thought they should be, but after he saved and exited the bios, the computer reset like it normally does when you exit bios, but then gave the same beep message as before. He told me that each kind of beep means something different, but he did not know what this one meant. If anyone could help me, I would really appreciate it.

If you have another computer, go to this site : www.bioscentral.com/beepcodes Go the one for your bios set, and it will give you the codes and what they mean. It sounds as though something isn't set up quite right in the BIOS setup. Probably just one setting is off. I don't think anything serious is wrong. Good luck. :) HTH
