Heat was not the problem cause it always worked in a range 50-60. but what I've done is that i scanned my pc for viruses and it detected a virus "Trojan:Script/Wacatac.B!ml" i deleted it and now it works fine .I'm not sure if this was really the issue.. what's your thoughts?Heat!
This is ultimately your issue proving you dont have a virus of some sort.
I used windows security.. thanks for your help and suggestions.I couldnt say for sure.
What software found that trojan? Also if you have one you are likely to have more than one, try running the free version of malwarebytes as well.
