A few nights ago i headed out for the night and like usual my comp was left on... but this night when i came home and "woke my comp up" it was sitting on the Black screen with white writing checking IDE drives. At the bottom it says..

" IDE Channel 1 no 80 conductor cable installed
Using 20 pin Power supply
CMOS checksum error - Defaults leaded
Warning! Now system is in safe mode.
Please re-setting CPU Frequency in the CMOS set up"

F1 to continue Del to enter setup

NOW my problem is the keyboard wont respond
ive pressed and pressed both F1 and del with no luck

i read that the CMOS battery might need to be replaced so i replaced it and still nothing.

I dont know too much about computers so im kinda clueless on what to do or what the problem is.

If anyone has any insight on what i can try or if you think you know what is wrong, that would be great!


Thanks in advance
Josh

Try a (temporary) replacement keyboard.

Do you get a normal boot screen?

If so...enter the BIOS and ensure that the time/date have been reset properly...elect to use the system default settings for everything...and then save the changes made in the BIOS.

See if the system boots properly then.
