Blank Blue Screen HELP :-(

Hi,
I have been trying to download windows 10 on my laptop (windows 7). It does the download and looks like it is all downloading fine and it starts rebooting and then it goes to a blank blue screen and doesn't go off the screen. I have to turn my laptop off just to do something on it, it then restores my old version of windows and doesn't download windows 10.
I then check the update and it says "failed" with the error details "code 8007002C"
Can some pleaseeee help me

If you receive Windows Update error 80070002 while checking for updates, you need to remove the temporary update files that Windows uses to identify updates for your computer. To remove the temporary files, stop the Windows Update service, delete the temporary update files, restart the Windows Update service, and then try to check for Windows updates again.

Try the above.

Unfortunately that hasn't worked... I did everything it said above to do, I stopped windows update and then deleted temp update files, I then turned on the updates again and that didn't work so I then downloaded the system update readiness tool and this still didn't solve the problem.
The download looked like it was working and got to about 80% and then it went to a blank dark blue screen for ages and then my laptop started to turn itself back on but restore to the original upgrade not windows 10 :-(
Can some please help me......
