Windows 7: WiFi connectivity drop and more

WiFi connectivity drop and more

Hello there,

I was running win7x64 just before win10 came live and had no problem with it. I decided to upgrade to win10 within the first week of its release and noticed a bunch of problems from the first use. After continuous gaming, but at random moments (it was happening whether I was playing a game for 20 mins or 3 hours):

1. The Wifi connection on my laptop would turn to limited connectivity. The laptop would refuse connection to all the other wireless connections available as well. I was not able to fix it in anyway, apart from a restart.
2. The sound would also start crackling horribly at the same time.
3. One of the CPUs would go berserk (as shown in the picture).

I thought that the win10 is still buggy and decided to replace it this morning with a clean win7 reinstall. To my very great surprise, the problems persisted. I just booted up Cities Skyline and was in my first 5 minutes of playtime, when the game suddenly crashed and all the connectivity dropped. Had to restart.

How can I fix this? Please help, it was frustrating already, but now it's gotten even worse.

It just happened again when I simply plugged in my mouse? Is it because of the motherboard?

Next time it happens, open a Resource Monitor and switch to CPU tab, sort both Processes and Services sections by CPU and see if you can spot what uses CPU time.

I think it has to be from the hardware, it happened again when I was moving my laptop around. Here are some screenshots. I reinstalled win7 now, the CPU thing is not happening anymore.

Nothing wrong with the CPUs in the screenshots (they weren't sorted by CPU) but wireless connection shows disconnected. The CPU activity from 1st post may have been some unrelated event. Check WLAN AutoConfig service (services.msc) next time it happens and try restarting it.
