uTorrent restarts my PC

[Zamorack]

Hy. First of all, please excuse me for my bad english. And, also, excuse me because these is an an double post. I have seen somebody whit an problem like mines, but i don't really understand the causes

I am using uTorrent for over half of an year without problems. But recently, he start restarting my computer when I open it or after 30-120 minutes. The error that I get in the "blue screen message" is :

STOP: 0x000000F7 ( 0x0000000D, 0x00000000, 0x00000000, 0x000000 )

The google search don't help me a lot. After getting some advice I upgrated Windows to SP 3 and try all the BitTorrent clients, but none of these worked. Also, I have try to reduce the priority of uTorrent in Task Manager to low, but these don't stop the crashes.

I want to say that now is the first time when my PC autorestarts, and these happens only when i use uTorrent.

Here are some informations about my PC, I hope that they will help :

CPU: AMD Athlon 1,67 Ghz

RAM: 768

2 Hard-disks, an original 40 GB one and an 400 GB recently added ( these may be the cause ? ) My system is installed on the 40 GB Hard Disk

VIDEO: 64 MB ( NVIDIA GeForce 2 )

Antivirus - BitDefender 2009 Total Security

What i have understand that can be an problem is the internet connection. I'm using Thompson SpeedTouch 330 Ethernet Adapter . I have try to update the driver, but it says me that can't find an new one. Now, it is 4.1.0.2

Thanks in advance for the help

Hardware failure, maybe your RAM. Run a memtest86 to test your RAM.
