My computer HP Pavilion A1140N died last Friday. No light comes up and it does not start. I opened it and cleaned the dust which had built up. Put the cover back. I changed the power cord and checked all the connections but it still does not power up. I connected to another plug but still does not power up. I need access to my data. How do I get it to work so that I can get all my data back. My tower PC does not have a green light in the back.
Previously have never had any issues with it.
