You didn't mention anything about the power supply
by Steven Haninger / February 6, 2010 12:00 AM PST

but that could be suspect. Generally, however, once they shut down the first time, they don't come back on. What you might do first is to unplug and plug in all the connecting components including RAM, add in cards, power connectors etc. Something making a poor connection can cause all kind of weird things to happen. I do want to make sure this is the computer and not the monitor, however. If it's the computer, your fans will turn on and off too.

Should be an easy fix since ...

you mention "My computer is only 6month old........."

It definitely sounds like a hardware problem and that is exactly why consumer goods are warranted.

Back up data you can't afford to loose and take it back for warranty repair or replacement. You might fix it yourself with a power supply replacement (or you might not) but most likely that would void your warranty.

Other than returning it for warranty repair all I would suggest doing is to open the case (DO NOT OPEN THE CASE IF IT IS SEALED BY A STICKER OR SOMETHING SIMILAR THAT SHOWS IT HAS BEEN OPENED!) and make sure all the paddle cards and RAM modules are fully seated.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
