Hi

Thank you for your query

From the error message that you are seeing you are having a issue with one or both of your IDE devices. These devices are your Hard drive or/and your CD/DVD drive

I would not recommned that you tackle it yourself if you have no PC engineering experience

Please book into a reputabe firm for further diagnosis, it may be that you may need to discoonect the IDE drive from the devices and give it a clean or alternativley one of the devices may be faulty

If this has been useful please leave positive feedback/vote/testimonial as

this will help me greatly - Thank you again

If you look on the top near the back there is a black oval looking button...you have to press that down...ALSO you have to press the same button on the bottom of the machine. It opens like a wallet but you have to press those oval buttons to release the latch.
