today I've started having problem on mine MSi GL62 7RDX laptop, out of sudden the CPU fan started to be go weird way, running on and off sometimes always at 100% speed, then it just runs and the laptop starts to vibrate like if u placed phone on the table.
I'm wondering if this is a software issue or fan got loose and needs to fix / replace.
As I said I'm not sure if this belongs here but I will appreciate any help.
Thanks for your time.
Shutdown the laptop, disconnect power and remove/disconnect its main battery for 10 minutes. Put it all back together and power it up. Does it do the same thing? If so, then you likely have a hardware-level issue.
