So I have re-installed windows on my barely 4 month old laptop 2 times already. I have a toshiba s855-s5251 that has 6GB RaM 750 GB HDD and is now rockin W8 but came oem style with 7 home premium.
For whatever reason I have shadow copies being made on my system without having set that up. I also seem to be forever unadding xml and fax printers that were never used from the home LAN. Now I noticed Windows SQL making outbound connections and there is always a delay in my internet connection starting up. It seems that it connects just fine but then a caution sign gets thrown up on the internet connection bar and then after x number of seconds  it finally has internet access. Right now as i type my mouse pointer has an hour glass next to it and it looks more like a strobe light for how fast it is flashing...sumone pease help me I feel like I should pull out every hair on my damn head.
oh yes and there is unauthorized access attempts to access process data or sumthin to that effect. Oh yes last but not least it seems like everytime i restore modem n router to factory settings within days i am locked out of it

is it possible for a man in the middle attack to lead to raid array or rather the creation of dynamic disk usage with hdd's? I swear it joined me to a domain I cant get out of. Admin turned to ADMINS with roaming profiles....

After clean re install what should I do?

Does even nook color need clean install?

How can i safeguard against this in future?

anything funny I can send to middle man that lets him know he is BUSTED and shame on him tsk tsk.

I am a student in ITT more of a networking and san field however.
Thank you for any help you may contribute in advance!
