Yes, i need help...
Since ONE YEAR my Computer (Windows 7) got this problem:
Every half hour, he shutdown itself!
Without "Bluesceen". Without warning.
It's like someone cut the energy.
I did a reset to the point back he works, nothing.
I've changed the powerdevise, nothing...

Belive me, i searched in the internet, but nothing helps.

So, i ask YOU! Did you know this problem? Did you have this in the past?

It's very frustrating: You hear music for a half hour, then silence....
You will upload a new picture, black screen, no energy...
you will answer a buddy, "Bamm!" you can write the whole letter again!

So, please, you experts here. Help or i've to shoot my "horse"
