CPU wont Power UP [Win 7]

[a4m187]

Hello There!
5 days ago, after i switched on my desktop computer, it booted normally and my windows loaded, post 10 mins after the booting is done, my computer just shut off.
I tried several times switching it back on, the CPU does not light up, the fans dont start, nothing.
I have tried changing the power sockets i place my plugs, has not worked.
Have tried a different power cable, still has not started.
Please help with the same.

My PC Specs are :
Intel i7 -3700
Asrock z77 Extreme 4
Corsair Vengeance 8GB DDR3
Asus DRW-24B5ST
Seagate 1TB HDD
Zotac 660ti GTX
Corsair GS600 Smps
Cooler Master Hyper 212 Cooler CPU

By CPU you mean computer correct?

Do you have access to another power supply to try?

Yes i mean the computer, and no i have no alternative power supply units to try it on!

Well based on your description think you'll need to get your hands on another power supply to try.
