Windows 7: Blue Screen Before Login

Blue Screen Before Login

I've been running Windows 7 since the end of January without any problems until yesterday. My USB Sound device wasn't working correctly so I restarted. Since then, I can't even get to the login screen. Once I choose I want to operate Windows 7 (I have Vista also a separate drive just in case something like this happens) the windows logo begins to load... but then it flashes the BSOD for a second then restarts. I tried running repair but it did nothing. I've unplugged the USB device and that made no difference. I wish I could say what the error code was... but it restarts very quickly. Please help if you can.

Hello AsuCaga and welcome to Seven Forums.

At first, there is a way to see what the error code says:

Start your computer, and before windows loading logo appears (right after the BIOS screen dissappears) press F8 key repeatedly until you see the Windows Startup options.

There will be "safe mode" and other options there.
One of them says something like "Disable automatic restart on system failure". Select this and press enter.

This will pause at the Blue Screen so you can read the error code.

Alternatively, you can boot from your Windows 7 Installation DVD and under "repair computer" , perform a System Restore to restore your computer to an earlier time.

Hope it helps.

Thanks for the advice! I'll have to try it tonight after class (I'm done at 7:30). I'll post back with the error message.

EDIT: After copying the error I returned it to last known good config and it is working. I think the problem is with the USB Sound device I have. Sound is working properly, but the volume control icon won't appear and according to Windows I do not have any audio. Here is the information I wrote down from the BSOD:
STOP: 0x000000D1 (0x00000004, 0x00000002, 0x00000001, 0x890B1EA3) and it said something was wrong with ndis.sys.

Has anyone experienced anything like this with USB devices before?
