I bought this model of computer and within 3 days after windows updates it crashed (blue screen) Took it back to the store and it was replaced with another. Within 24hours after windows updates the new computer crashed (blue screen) Took it back to a different store and had replaced with the same model (different batch) with a few days after windows updates it crashed again. 3 different computers - all crashed with looping bluescreen issues. I did research on the internet and found quite a bit of info regarding this known problem. Why are they still being sold? I rang Lenovo, who remoted into my computer and "fixed" my computer which lasted for a couple of weeks, then once again (after windows updates) it crashed with blue screen looping. After contacting Lenovo again they have asked me to return the computer to the the purchased store for a refund or exchange. I liked the computer when it worked. It was a little noisy when running. The fingerprint sign in was very handy. Bu
