Hi,
since purchasing the lappie have you run Windows update? You might be missing important updates so it's worth checking.
Try these scans and see if they help any:
File scans
Look in your start menu for the folder 'Windows System' (near the bottom of the list) and inside you'll see command prompt, right click on the command prompt icon and click run as administrator. Type (or copy and paste):
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.
Finally check for malware by running Malwarebytes (it's free)
Free Anti-Malware & Malware Removal
Hope this helps but if not please post back.
