I purchased an 7050 sff for my in-laws. Every day or so it just locks up, mouse and keyboard do not respond. The only way to get it working again is to hard power it off. It does not show anything in the event viewer other than the hard power off. I contacted dell support and they had me check all the drivers and update them as well as the bios too. After about an hour on the phone with support they decided that the ssd needed to be upgraded at an additional cost. ( keep in mind this system is two months old ) The problem arose the first day it was used, however I was not able to look at it until after the first month was over. So, they will not return it. 

My question is has anyone else run into a problem like this and can offer anything else to try before throwing more money at it in hopes if maybe fixing the problem ? Thanks for any help.
