Megatouch issues with loading...help please

[Tampamike1234]

I first got error code 271 which was to check date and time settings.
I researched and determined it could be a bad backup battery. I replaced , but now I get the two following error codes:
251 system cams checksum bad
280 Previous boot incomplete

Then just sits idle and never goes past that screen.

I am a novice to these games and computers in general. I purchased this used for family entertainment. It worked perfectly for the past 6 months and now this.

Any help would be appreciated!

Thank you very much!

i'm not sure what board you are talking about specifically...

generally if the battery dies or gets low, the data stored in the BIOS gets corrupted. (this includes such things as harddrive parameters and memory/cpu configurations) during boot the computer does a check of the data contained in BIOS, if it doesnt "Add up" during the checksum test, it throws the checksum error. this is so the computer knows the settings data it's loading is good or not. (potentially destroying something in the process if the data was bad.)

usually all that is required is to change the battery, go into the BIOS settings, (press delete or f2 or f12 or something during boot) and set the date and time and boot options etc.

this should get rid of the message and boot up after that. (the computer is holding off booting to prevent possible data corruption)
