I had this did oven reflow 220 degrees C for 8 minutes worked but when i went to put windows on (to sell it) I left it overnight finishing the install the next morning it was doing it again motherboard seems to overheat make sure you get it over 195 C when you reflow as that is the solder melt temp take it out after 7 minutes (be careful its delicate when solder is soft) let it cool my board was twisted after but fitted and worked ok
