Black Screen when left without activity

[MicroMina]

Hi everyone

Last night i left the computer downloading using utorrent and in the morning, there was a black screen. First, I thought it was sleep mode, but nothing resumed it. I tried enter, escape, space, pressing keys randomly, even the power button.

I had no choice but to turn the computer off with the power button.

I made sure that its not the power options, I use windows vista and use the High Performance power plan, and I made sure that the computer doesnt go to sleep automatically, and turned off "turn off hard disk". I just tryed everything.

I guess the computer goes into something that can't resume from.

I checked every software on my PC and its just the ordinary programs that can anyone have.

Some of you might think now: "What does that have to do with utorrent??? "

I tell you it DOES have something with utorrent, because i used to have bitcomet but I switched to utorrent.

And I have left the computer overnight with bitcomet and it worked fantastically.

(I tried utorrent for 3 hours also but it did the same thing)

My PC is BRAND-NEW so its not hardware I got it from 5 days !!!!!!

MY Specs:

AMD ATHLON X2 6000+

2GB of RAM

GIGABYTE MOTHERBOARD M61P-S3

INTERNAL VIDEO CARD (NVIDIA GEFORCE 6150 with nforce 430)

MICROSOFT WINDOWS VISTA ULTIMATE

Thanx all
