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

Had the same problem here ( just putting one back together now).

Likely a PCH issue, so basically a case of dumping the board and cutting your losses. This model is having a lot of this issue.

Warming the PCH up at 150~180 probably might give you another couple of days but it'll fail again soon enough.

It's NOT likely a ball problem, rather the issue is in the internal gold connects of the chip itself.
