So to start off I was gaming for 2 hours last night and turned the pc off and after went to sleep. The morning after when I went to check my emails the PC was extremly slow. I have never in my life had this problem which is wierd but I did have a very very wierd problem that noone could solve but a simple windows reinstall which made it work perfectly until now. I have absolutely now idea how to describe this problem but possessed. The internet worked fine for 2 whole minutes and then the pages kept loading for an infinite time even though it says I'am connected with no issues at all. I check the laptop and phone (writing this from laptop) and they all have superb connection making me think something is wrong with the PC itself it is wierd to the router with a very long cable although not needed but only one i had for the moment. The pc will only load up youtube for some reason but nothing else, again it is extremly slow so I ran malware bytes and it found nothing at all I troubleshooted twice and nothing it says everything works fine, I restarted the router twice and nothing same problems, I restarted the PC twice and still nothing, im freaking out that something inside it has died or something but I'm hoping something is wrong with the cable from the router. I opened up the PC it is a little dusty gonna clean it soon but that shouldn't really be the main problem right? It's so wierd that it went working fine to being a vegetable in 9 hours it's insane. I don't know what else to do, please help..
