When everything works its great when it doesn't its horrible

So I go and buy a new laptop for TEAM in August and now it is not working right. THe Ctrl+X, V, and C combinations are no longer working. SO what do I have to Do send it back to Toshiba in Tennessee because the "think it is a hardware issue" Is it so much to ask to have aproduct work??? I am going to wait to send it back after thursday's marretch session. I can't stand it
