Hi welcome to the forum Turn the PC on and when it come up to the menu use your arrow key to go down to start in safe mode and press enter on the keyboard. Duz it start in safe mode?

Hi Bigdummy, welcome to the PCHF.

I highly doubt the cmd ipconfig you typed in caused the problems your having.

That command gives you your IP address, and makes no changes to it. I'd say it was just co-incidence that it happened when you typed it in.

Unfortunately we really need to see that Blue Screen to see what's going on properly. The first thing I'd try - is pull the power cable out of the back of the computer, and hit the power button 10 times (while the cable is unplugged). Plug the cable back in, and see if you can boot up now.

Let me know.
