Question about Acer Aspire 5742Z-4200 Notebook
A computer that is shutting down as opposed to rebooting usually indicates a heat problem. The computer will shut itself down to prevent damage. If it will run long enough for you to log in and use it for a bit. You can download and run speedfan. It will give the temperatures from your computers sensors. Usually the only one we care about will be the CPU. If it's getting up around 75 C then you certainly have a heat issue. You will want to go to radio shack and get some "thermal compound" the best one is Arctic Silver 5. It's about $10.
Service Manual for your laptop
Once your at the heat sink remove it and either on the heat sink or on the cpu itself where you see some grey compound. If there isn't much there put about half a pinky nails worth of the paste on it in the center. It will heat up and spread out on its own.
Also if there is a lot of dust, use some canned air to blow it all out.
