This is my 3rd re-install.
Its Window 7 Ultimate x64 retail full copy (not upgrade).
It was a clean install on a custom system that is new. It ran memtest for 3 days stable.
This install has been up for less than 2 months.
Ive hadn't had a witnessed BSOD, but did find the PC had sitting at the login screen when I came home.
Last night I had Rhapsody on and was not at the PC- again, I went into the office and saw it had restarted.
Then I was at the PC just doing some work and did see the BSOD with USBPORT.SYS. But I read another post that said it might be something else.
My file is attached as per instructions.
I might have to go buy Vista if I cant stop this!
