I stripped my heatsink screws which are too tight

hey guys, I own a nitro 5 gtx1060 16GB.

I bought it last year and have been experiencing fps drops and my performance is affected. So i read online and found out that other nitro 5 users are also encountering the same issue and many managed to solve the overheating issue just by reapplying the thermal paste with something of better quality.

So I took apart my laptop and as i was attempting to unscrew the heatsink, i realised that the screws were too tight and my screwdrivers could not unscrew it ( i was using the normal screwdriver, not those electrical drills ones ). And after several attempts with other screwheads, i was still unable to unscrew it. Now all of the screws are stripped and I still unable to remove the heatsinks.

Tried using duct tape to wrap the screwdriver heads to unscrew the stripped screws but it didnt work

Any suggestions on how I can unscrew those TINY screws which are stripped?
