As the title says my pc started freezing after i cleaned old dried up thermal paste, and applied a new coat. Granted the thermal "paste" is thermal Grease and is 7-8 years old, my question is, what causes the pc to freeze?, i can boot up windows get in, and in like 2 mins the pc freezes and crashes, the usage in task manager are incredibly low 0-1 procent, and in bios the temprature is around 43-50 celcius. Could i have damaged anything while applying new thermals?, what can i do?
