I have had my Acer Aspire T desktop for four years. It has freezed up since I bought it. Lately it has gotten worse. I bought a ssd harddrive and put it in, plus I loaded a new version of windows 10. It still freezes up. It mostly does this when I am using it. It will also do it when it is in standby mode too. I assume it is my motherboard. Any ideas. Thanks for your help!
