About two months ago my DC jack burnt out along with my motherboard. Luckily I managed to get MSI to cover the repair and to top it off, they upgraded my motherboard and graphics to a GTX 670m. Here's a thread where I talked about it.
Burnt out DC Jack and Mobo
I finally received it back but unfortunately the fan has a solid buzz every time I turn the laptop on. If I turn the fan to max and leave it running on max for 5 minutes then turn the fan back down the buzzing disappears until I turn the laptop off for a few minutes.
I pulled it apart but couldn't see anything wrong with the fan. I'm debating if I should try to oil it next. Does anyone have experience with this type of problem and any recommendations for me?
