OP,
I have to be rude, but you are either a complete novice twelve year old, or a slow troll.
If the former, you are in a great place to learn - seize the opportunity.
If the latter, congratulations.
The requirement to isolate and explore your symptoms has been on the table for two pages.
You seem not to have understood anything that has been suggested.
You talk like you’re trying, but that’s all.
Your understanding of the very basics is woeful for anyone over 15with a genuine interest in solving the problem.
Take-aways:
Isolate the symptoms and causes.
Only change one thing at a time.
Don’t skip steps because you think you know the answer.
