Hmm... Well try removing the original and then re-installing. You never know, a fresh copy may just help?
Also to clear any system corruption you might have (you have been blue screening so it's possible some files have become a little fouled) run these scans:
File scans
Look for command prompt in the start menu, right click on it and choose 'run as administrator'.Type:
sfc /scannow
press enter and await results
In the same command prompt and after the above scan has finished type:
dism /online /cleanup-image /restorehealth
Press enter and await results (longer this time).
If the first scan found files it could not repair but the second scan is successful, run the first scan again using the same command prompt box and this time it should repair the files found.
