Your choice but here.
We began to have issues with the i7 based laptops at the office and on a lark (actually something we know about) we set Windows to limit cores to 6 rather than the 8 the i7 has. The machines have straightened up and are now very reliable.
I don't think any warranty work could have done as good a job as this simple setting change.
