Have you tried other wall sockets at your house?  If nothing else changes that's the first place I would look.  Are you also sure you haven't unseated something during transportation?

I have tried each and every socket in my home.All the cables and connections to the PC are intact and transportation is done by me very carefully as I have it in my laps while carrying.I am suffering from this problem since four days.The PC wont turn on

Where do you live?  I only ask because Im curious if the power delivery in your Country may be faulty(dirty)?  Would a UPS fix this if that's the case?

I live in Hyderabad,India.I use a UPS (1000VA/600W) which does not help me.

The weirdest thing is all the household appliances like microwave oven,AC,refridgerator work very well and they consume more power than the PC

How many times has this occurred?  Is this new (the issue, as in this is the first occurrence or has this occurred daily for a few days)?  Could you have possibly disconnected the Start Button pins during transportation?  

 

If I were to have this problem I would take the PSU out, and jumper it.  That way I can find out if the PSU works without being hooked up to anything but the wall socket.  

Depending on what happens I would drive to the shop and try it there (if it didn't kick on at home).  If the PSU kicked on at home I advise you to google "breadboarding a PC" and continue building the PC that way at home until you run into another snag.

This is my first time encountering this problem.

 

The PSU runs without anything connected to it except the power cord.However when I just connect it to motherboard and CPU ...it does n't run.

The guy at shop did not even open the case of PC and plugged in the cord(had this experience three times )...then bingo....PC runs

Is your motherboard solder points or the case standoffs themselves coming into contact with the motherboard or case (I.E. a solder point on the mobo touching the metal standoff, or an extra metal standoff on the case in the mobo tray you didn't remove touching the mobo causing it to short - I.E. PSUs now-a-days wont even begin to try to turn on).

 

Google "breadboarding a PC" and follow the directions to a T.  Build it 1 component at a time as it tells you so that you can start to eliminate possibilities.  

 

Right now Im leaning towards an extra case motherboard standoff that is making contact to the motherboard and however you position it at home, or during transport, its just not touching at the Shop.  

 

At least that's what I would do (breadboard)

Don't have the mobo speaker...will update the status tomorrow as I cant get it now (23:33 here)

Understandable - sucks your going through this

[Crazy Freak]

Just checked everything,I think the problem is with the motherboard.no post beeps and cpu n psu fan does nt run...still don't understand how it worked at thr shop...will drive to shop right now and check if mobo is working

Did you take your mouse and keyboard with you, or did the repair shop use their own?

If a pin is bent on the mouse/keyboard usb socket, then it will stop the pc booting, as it detects a "ground".

The PC shop used their own mouse n keyboard...the pins are not bent...I checked them carefully..the PC doesn't run without external devices connected

[Crazy Freak]

I don't know but the components work at the shop while breadboarding them today .....this is wierd

 

Video at shop(video 2)

 

Video at home(video 1)

[Crazy Freak]

And the electricians whom I called are dumb and they say that PC is faulty as every other applicance is working(even after showing them the video )...Can I get a solution for this problem????

[Palden]

Well, first off, the first video you posted shows you tried booting without RAM in. The PC will never POST without ram. Second, make sure that you use the correct RAM slot on your mobo if you're going to use only 1 ram stick.

The video might be so but I have done booting even with RAM...just brought an electrician to home....changed some wiring in the home....bingo...PC runs

 

Thanks for the help guys

[Tristerin]

Bad wiring of some sort, at least its fixed!
