Try replacing the battery after cleaning the contacts, make sure it's fully charged. If that doesn't work try a different battery, if the camera works with the new battery then your old one could be faulty!

Please find list of Canon error codes

http://www.camerahacker.com/Canon/D60_Error_Codes.shtml

From the same site...
Err 99: SYSTEM

DESCRIPTION: This error occurs if there is an internal malfunction detected during the camera's self-checking procedure that's executed before every attempted exposure. This is somewhat similar to the flashing 'BC' warning that occasionally appears on EOS-1 series 35mm SLRs.
REMEDIAL MEASURE: Try releasing the error by turning the main power switch OFF and then back ON. If this does not solve the problem, have the EOS D60 examined by a qualified service technician. Please be careful to note the conditions under which the error message occurred. This error is similar to Error 09 or Error 10 on the D30.

Hope this helps

It could be a CF card error - try another card and if it's OK do a double format on the suspect card before re-trying it

Thanks everyone, did all the checks still no joy been on the phone to Canon seems it could be a fault within the camera body so it's going off to canon for a bit of surgery.
once again many thanks

Did you solve the problem? I had this error with my 10D, and it turned out to be the 70-200mm lens, which I replaced. I found this out by hiring another lens that worked perfectly well.

Hi bpw,
On canon advice sent camera body off to be fixed. last week when I phone they were waiting for a part, the girl on the phone couldn't tell what part that was exactly but I should be getting the camera back early this coming week. fingers crossed!
