Here it can be quite a lot of options, what you can do is take them one by one and see which one it is. Check if on your motherboard is any warning lights, try to re-seat Ram or video card and check again. Shutting down can be even from faulty motherboard or even HDD. Check the temperatures as well, if it overheats it shuts down to protect components. The power supply could create problems as well. To save your data if you don't want to repair your pc and/or you have another one just transfer the HDD and copy the information. Try to update the drivers as well. For password related issues depends on what you are using (windows, ubuntu, mac) and how it was set-up. There are ways around it but depends of a lot of factors.
