So I have the same Blue Screen Problem when I plug in a USB or move my USB mouse form one port to another.
I tried a fix I found where it said to edit one reg key and remove all usb drivers.
In the process of removal, one driver in particular shuts the machine down.
And then I get no signal to the monitor, on boot up.
I left it off during work today came home and it powered back on with just the Keyboard (particularly just as the KB was plugged in) and a different mouse.
Everything seemed to work as it did before....but with the usb problem as I plugged in a 3rd device and it BSOD'd
Then I tried the remove driver method again (I know I know) and sure enough that was the only predictable thing where it powered off on what I am guessing is the same driver.
I have a Asus Rampage IV Black Edition, I am guessing one of the USB devices controls something on the Mobo?
So currently I can power on....but see nothing on the screen, with just keyboard and mouse in the specific ports they were in before.
Any ideas what I can do form here?
