Hi Cat,
first, if the bsod starts up again then use the app found in this thread and post the results:
Link Removed
Try running these scans to see if helps with your current issues:
File scans
Find Command Prompt, right click on it and run as admin. 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.
If it doesn't help then please post the details of the machine your using as...
