On/off switch lights still when turned off. Other problems related?

Hi guys. Im all out on this one and about to buy a new computer. I will list first problems then a little history what i have done.

- Network lagg in game. Csgo Chokes up to and over 10% when gaming (always. got 75/75 fiber optics. Shold not be a problem with the connection. Is also directly in router)
- Computer turns off but on switch light still lights. (Press on/off 10sec. then light goes ut and you can start again. Computer is completely off even if light is on)
-New mouse to 70dollars shuts off and on sometimes. Makes wierd twiches ingame 90degrees moves when i move. Often seeing up in the roof suddenly. (seen problem one time before on forum)
-I now use a dvi cable. Becouse displayport cable makes computer not start. When dp cabel is on, i can plug out power to screen. Still light in the lcd screen. (this is an expensive gaming screen 144hz)
-Sometimes game stops working. Nividia experience say ( screen driver stopped working)

Also important to know. The computer has never had earth. only +-. I have used a lot of money to upgrade house so that it now has all connection needed for the psu.

It all started with my 3 old mouse stopped working as my new does. just a lot often than the new. Then 2old i plugged inn the was a spark at the usb port. That mouse seemes to work finebut it was just a mouse so that the disconnect would stop.

Then comes the new "expensive" mouse. This one showed alle the same problems.. and i started with changing MB becouse of the spark i got on the other mouse. And then the new problems starts to come bit by bit.

Some say that maybe psu is bad ( but this is 0.5-1 year old corsair 750W gold witch was very expensive. So its hard to belive this is the reason.
Also there might be other parts in the computer who can do this. But i tryed to unplugg all with no luck getting it started. When i was using the DP cable.

So far im come to a point where i see myself needed to change PSU/MB/CPU/RAM at once to get rid of the problem. Also i got som strange readings trying to messure out groundings in usb port. Need an advice on how to messure this correctly.

I tryed to messure psu but the psu is all in black wires so i didnt know what cabel goes to what (probably could find this out with some readings and time.

Also. i got a new mouse. same bradn (Corsair Gaming M65 RGB FPS) Same problem. A friend tested this mouse but problem is same to him.

So guys. This is my problem. Hope someone can give me som input on this =)
Sorry for bad english. Not my main language.
