pc lags when multitasking and random crashes

[ASUS fan]

pc lags after hit by mistake in front of the case when i pulled the chair,i was playing rocket league that time and i saw a huge pc framedrops the mouse was stuttering too so i restart my computer and i was hearing a beep beep by my pc i think it was the sound when u havent connect the cpu cooler so i oppened my pc and checked the cables and everything was fine so i closed the case and trying to power it on again but the same problem,so i unplug my cpu and gpu cables and after that it oppenned normaly so i went to play again and when i pulled my pc a little bit again but this time with careful cause of wifi signal and lag started again restarted my computer and everything was fine after days this problem was solved by itself even if i pull my pc but i have notice that when i try to stream something to my friend my performance is getting drop a little and when i am in training in rocket league and joining waiting to join a match i notice that there is a little lag until i join the match so i m not sure but i think that my pc is worse now at multitasking is there any way to fix?

Just so we're completely clear, when you mean "lag" you mean frame rate or internet lag (rubber banding etc)? 

 

If you're talking about performance, then your GPU or CPU might be downclocking and making you get worse performance due to high temperatures. 

 

Could you tell us your specs?
 

Also can you play games with a monitor software such as HWINFO opened and tell us the max temperature values of your CPU and GPU after you play?
