Does covering the gpu cause fps drop

[shafeeksownspace1999]

My specs are
Intel Core I3 3.2 ghz
4gb ram
Geforce Gtx 660
500gb*2 hard disk

Here's what happend
I watched a video how to make your gpu look nice .
And I started working on it , I glued on the top of the gpu circuit and pasted a cardboard with Msi logo on it
After doing that the games that I used to play with a decent amount of fps got worse and then I've realized that I damaged my gpu so that I removed the cardboard thinking it would go back to normal .but it didn't help.

Should I buy new one or is their a solution

I would really really appreciate if someone could help me out
CHEERS

Without seeing what you did to the system bit hard to tell what you may have done, could be you messed up the cooling to the video card. Have someone there that knows about computers well look over the system.
