I have an 2015 model Aspire E14 notebook presenting problems for almost 12 months.When turned on the Acer logo appears then the screen flashes constantly making it impossible to sign in. A repair was made by a "qualified" PC repairer but I was told that the repair may last between 1 month and 1 year.The repair lasted 1 month . Can anyone give me an indication as to the fault and approximate cost to have a permanent solution. The new cost was only around A$500 ( was a gift) but I did expect 5 years troublefree use as it is used daily for email checking only.
