Have you tried resetting your BIOS?
Can you verify that you didn't change anything you weren't supposed to?
 
When I booted up with the new cmos battery I got the option to reset to default settings and did
I tried getting into the bios after the second restart and was unable to I noticed in the boot order options all that was booting up was floppy drive which I do not have and the cd drive I don't have the 3rd option to turn on the drives I disabled
 
yes i can feel it booting up
i got into the bios all thats listed in boot priority is..
1: floppy drive
2: HDD:pM-WDC WD3200J
3: CDROM:SM-SONY CD-R
 
now all im getting when i boot up is "reboot and select proper boot device or insert boot media in selected boot device"
 
You may want to check how you have your computer set to start up. It could be looking at a device that is not installed. Check in the bios. You should see a menu that will allow you to choose which devices you want to use to boot on startup. Hope this helps.
 
i cant even get into bios now it goes right to the "reboot or insert device screen" i inserted winxp cd went to repair the cmd: Fixboot gives me "cannot find the system drive, or the drive specified is not valid.
Fixmbr
Bootcfg /rebuild : error failed to successfully scan disks for windows installations. this error may be caused by a corrupt file system, which would prevent bootcfg from successfully scanning. use chkdsk to detect any disk errors.
chkdsk : the specified drive is not valid, or there is no disk in the drive.
