BleepingComputer.com: Computer showing errors on startup

Hello, my brother's computer started showing errors on startup not long ago. It runs Windows Vista Home Premium and it's a Dell Inspiron 530. It started showing "Keyboard Failure" but now it's showing "CMOS Checksum Error Defaults Loaded" and "Diskette Drive 0 Seek Failure" and at the bottom "Press F1 to Continue F2 to Enter Setup" but I can't press F1 or F2 because for some reason the keyboard is not working on the computer. Please help us c: Thank you. :D

Let's start by replacing the cmos battery (on your motherboard) and see if that helps. It's the simplest first step.

Ok :D I gotta go get the new battery first be right back.

It may or may not be the answer (the errors you report can be caused by a dead cmos battery). But again, it's the simplest first step. If it doesn't fix the problem we can start digging deeper.

If replacing the battery doesnt work I would try using a spare keyboard if you have one lying around...Just to test

Sorry about answering so late, I forgot about this It didn't work, and yes. I've tried connecting a different keyboard, it didn't work either :\
