I have a 2 year old Compaq Presario CQ56 installed Windows 7.
sometimes it turn on, fan spin, led comes and power off instant. but sometime Nothing happens when turned on - no lights, no buzz from the fan.
This is my backup computer which isn't used much - worked fine with last use, but has been shut down for several days since.
Any ideas and/or suggestions?

If you have enough skills - find a video/manual about how to disassemble it and try to look inside and check if something is wrong here (i.e. lots of dust). If you're not skilled enough - take it to someone who is (i. e. a service center worker). – montonero – 2019-01-24T11:34:14.940
And check it's power cord/outlet of course. – montonero – 2019-01-24T11:34:41.547
Maybe the power brick is bad. – Moab – 2019-01-24T14:08:49.477
