start-up problem after using F-Secure Booster (cleaning and speeding up)
After cleaning and speeding up with F-Secure Booster, my laptop has big problems to start up: a blue screen during about 5 minutes or more before starting up. After restoring my system at a point before using F-Secure Booster my laptop start up again in a few seconds. Thus I can not use F-Secure Booster anymore without having start up problems . Anyone can help me to solve this probelm ?
My Laptop: HP Pavilion HP 15-pn045nd, system: Windows 10
