I'm sure this has been posted many times and I'm sorry to flood the forum... I cannot log into my main account on my Toshiba Satellite L755D-S5106 laptop I can click the guest one and run programs and what not from there... But if I click the main account it is stuck on a black screen only... Also lately when I click it..it will load up black but then a blue bar on the bottom will pop up and it says, "Interactive S..." with an X to close it but nothing else shows. I can access the main account in safe mode but can really do much.... Any help would be greatly appreciated!!!!
