I am unable to open in safe mode or normalmode. .DVD/CD drive is not functioning. When I start while tapping F8 windows repair opens. No restore points available to restore to an earlier date. I tried to open with a USB stick provided by my internet
provider and I get a message, "Your computer does not have a wireless Net working Adapter and cannot connect to Internet.My forst problem is to purchase a compatible wireless net working USB adapter to connect the Internet. Second problem to purchase a COMPATIBLE External DVD/CD player to clean install windows to factory default. I welcame constructive suggestions form my respected Acer community. Thank you DharmaSD
