Sizzling, Stuttering, Decreased performance on Gaming..

Hi everybody.
I was playing Far Cry 4 without any problem but for 3-4 days it became unbelievable laggy. Sounds and screen started to sizzling and stuttering. I have Toshiba S55-A5279. i don't want to format my laptop. So if there is anybody can help me please don't ignore me. I am open to all solutions. By the way this problem started to occur all the other games i played. I have updated all drivers but no solution. If you ask me what are the changes that made 3-4 days ago,well there aren't any vital changes. I downloaded some video, played games ext. Windows update is closed. I have looked event manager and didn't see anything uncommon.
Thanks..

Sizzling? Do you mean from the speakers or an actual sizzling sound from inside the computer?

Restore point before this started?

sizzling.. maybe you are frying your hardware??

post your specs on the toshiba.. your probably over-heating... i have so many stories to tell you if thats the case..

i didn't get it bro. what exactly should i do ?

google fan control on your toshiba laptop model.. and start there by cranking the fan all the way up.. then if you have an intel processor start with looking into undervolting.. but dont try any of that without asking about undervolting and googling everything before..

also start trying to check your tempatures.. look up realtemp.. look up hwmonitor..
