If this doesn't help, maybe reprogramming the BIOS through BIOS update will do the [email protected] its kinda bit old PC with a P4VP-MX Asus motherborad....But it is important for the relevant details of the MB.Mike Just a clarification CMOS and cmos battery are not the same. Recently I did a clean install of windows XP on my PC, everything goes smooth and no errors. Thanks & good luck Cmos equals continuous metal oxide semiconductor. I've been doing some reformat and clean install before and I never encounter this problem before its my 1st time to have this problem..But after a day I use it and shut it down for an hour and when I return and turn my PC again this problem comes out... It is the small disk battery found on your motherboard. (it's probably this) = but sad to say it doesn't fix the problem still there.... T_T As dbarker suggested please post as much detail as requested.I have tried the following: I have unplugged all devices from the mb except for one stick of ram and the proc.
It appears that the computer is looking for a disc with the BIOS file on it. Since you lost the support CD which contains the original BIOS file, uownload the latest BIOS update from Asus (previously linked) burn it to CD or copy it to floppy if you have one.CMOS is a circuitry design/chip while cmos battery (mostly CR2032 on computers) powers the cmos so that it can retain whatever data the cmos holds even when for example a PC (with the BIOS configuration) is turned off.As to the OP's problem, maybe clearing cmos through a jumper on the motherboard might resolve the checksum error.As this procedure, if not done right would render your pc inoperative, although very remote. - Okay first of all thank you for helping me here,,,, I go to the site and read the instructions on how to update the BIOS.... When the ASUS Logo appears, press to show the BIOS Boot Device Select Menu. Then put the floppy disk in the drive before you start up.tech27, The best place to start is in your motherboard manual. Insert the support DVD into the optical drive and select the optical drive as the boot device." but how could it be because everytime I boot up this problem will pop up and the logo wont appear.. Also when I boot up and that screen appears my Keyboard is not accessible that is why I cant use the Shortcut keys or the functions keys... Also try to clear CMOS memory first as I have suggested in one of my POST above. If no floppy, follow the instructions for building and burning a cd/dvd disc for flashing the BIOS.
