You should consider to clean your Laptop or PC at least once a year. If you don’t, it may cause you problems like overheating, blue screens, slowing down and eventually dying.
Interesting case here. Customer walked in with a beautiful Canon EOS 1000D that wouldn’t take pictures.
Kept showing an error saying Memory card locked (presumably the SD card).
Was quite expensive on purchase, so the customer really wanted to get it fixed, rather than have to buy a new camera.
We diagnosed it and found it to be a faulty SD card slot, and needed to be replaced.
Job: Replace Canon EOS 1000D sd card slot replacement.
