Well...did you try the suggested options?
If you have "many problems" on a 2-week-old system...seems that either you or your system is at fault.
If it's the system...send it back for repairs.
If it's not the system...maybe you need to review what you have done and how you have done it...and make some changes.
The error message you posted is pretty common but I don't see where anyone has a real clue to a solution.
