Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
I'm sorry to hear about so many problems having happened. Let's try to get through them.
First, I don't know what kind of computer you have - a Windows PC, or an Apple computer most likely - so please let me know.
Second, some of your problems sound as if you might have a malware, adware, or spyware issue - a login causing a crash or software breakage, and drivers not working, sounds somewhat like such an issue. So, if you do not have an anti-virus suite of good name and repute, I would advise you to obtain and install one on your computer. I'm not sure of which to recommend at this point since you may have either an Apple or a Windows PC as far as I now know - but I think Avast comes in Apple as well as Windows versions. Double-checking, I find that is indeed the case:
But tell me what security or anti-virus software your computer has on it, and what computer it is, and I will advise you further.
As for the printer driver problem, if the issue isn't a virus or malware problem, we will solve that quickly enough I feel fairly sure. Please tell me what maker and model of printer you have, and I will advise you further.
