hi guys.  I don't know why i have posted it here but i am in need of help. I started my pc today and as usual i went to forums but after few minutes my pc showed a blue screen saying  "your pc has been shut down to prevent damage to your pc" then it dump the physical memory and then i restart and the problem occured again. I ran a boot scan with avast anti virus. It found some viruses in windows /temp folder. But still the error occurs. I also started it in safe mode but no use . I have important docs there and i don't want to loose then so please help me anyone.

Edit: i got the cause. It is because of network. Because when i unplug the router, the error didn't occured so now any help
