Whenever posting questions on these forums, please give us as much information as possible about your computer. Depending on your issue, we might need the operating system, processor speed, amount of RAM installed, brand name of the computer, (if there is one), and any EXACT error messages you are receiving, and anything else you can think of that might help. The more information you give us, the better informed our answer will be.
Did you make any changes to the computer recently that could have caused the issue?
Hope this helps and let us know more.
My computer shuts off before it even boots up. I turn it on and i receive a blank black screen then it shuts itself off. If its a lack of memory then why now?
