I have tried CPU mining, primarily to educate myself regarding the mining process. I left the Bitcoin software to run for over 24 hours, making certain that it had downloaded all the blocks (I double checked on another website for the current number of blocks).

However despite downloading all the blocks, the Bitcoin software did not quote a hashrate in the bottom left hand corner, so I assumed that I had done something wrong. I tried to upload a screenshot of my Biotcoin software to this forum, but the forumsoftware did not seem to be working as I could not upload the screenshot.

Any suggestions as to what I'm doing wriong appreciated.
