My cat stepped on the keyboard and turned the screen 90 degrees. I called the store in Yonkers where I purchased the computer. After waiting on hold for 20 minutes the guy who answered offered to answer my question -- for FORTY DOLLARS!!!!! He said they offer tech support for the first 90 days......While waiting for him, I opened a Chat window on their site. "Alex" said hi, then I asked my question and he/she disappeared. Needless to say, I will never buy a computer from Micro Center again.Btw, right after the guy said $40, the guy who has a computer repair shop near me texted me back. It's ctl-alt-up arrow.
