Bad BIOS Checksum

[EdoKoi]

i just installed a GeForce 6600GT video card and another 512mb stick of RAM.

so how was it working prior to the upgrades?

maybe you have a bad stick of RAM, that sometimes cause instability at boot up.

also...what slots did you put the sticks in?

check your mobo's manual and see if it's supposed to be in a certain order.

also, take out your vid-card and reboot and see what happens.

try it w/ the new stick of RAM too.

Scotch tape didn't work well for me when I had a slot that wouldn't hold the battery

^^ did it melt or something?

i'd think electrical tape would be more forgiving on electronic devices.

that may work....

Could allways try thermal paste that has silver in it, but then again there goes the mobo.

bad checksum mean you bios does not keep the memeory of things, like time and your bios settings. it is related to your battery, nothing else

sometime the pin for the + part of where your battery go gets push in too far, and pulling it back out will usually fix it. or you can have a bad battery.

i got an interesting story. i took out the battery and put in back in. i restored the BIOS from the cd. the BIOS version on the cd is 1.02. i downloaded the newer 1.07 version and then my computer started acting up again. it kept giving me the bad bios checksum. i decided to clear the bios again and i just installed the version 1.02 from the cd and i haven't had any problem booting up for the past 3 days. could the bios file i downloaded be corrupted or glitched?

anyone?

It's not the BIOS. Bad BIOS Checksum is related to the CMOS battery only.
