My laptop is having said problem specifically when connected to my home wifi. I'd reformat the laptop. I'd analysed dump file using windows debugger said an issue with my wlan driver so I removed the laptop's wifi card & used only usb wifi dongle but the problem still persist. https://1drv.ms/u/s!AtmFnUq8vggggbxVdyOrsIJmC6VAkA?e=3GzWol this is the latest memory dump file I have not yet analyse it, I would be much appreciated if fellow forumers could analyse it & give your input on what really happened. thank you.
