Acer N50 sometimes it doesnot turn on

Hey, I had a similiar problem with my pda few years ago. It didnt turn on, or then the startup info screen came up and the pda just froze or shutdown. I had to hardreset also to get it runing. After a few weeks of this the pda died. It's possible that your pda is about to reach its end. There could be other problems. One thing you could try to do is reinstalling the operateing system if you have such. You can also buy newer operating system upgrades but might not be available for your product and it might not fix the problem if it is a hardware issue. Good luck.
