It was a quick and reliable machine for 13 months. Then I walked in after 13 months and it would get stuck at the Acer screen. I tried everything I could online and nothing fixed it until I took out the CMOS battery for 20 minutes. Put it back in and it powered on and worked great for 5 minutes...until it got stuck at the ACER screen again. Toast. It will cost to replace than to fix.
