I reapplied my gpu’s thermal paste and pads and while in the process I lost one of the gpu’s heat sink screws. I don’t know if it’s the missing screw that causing this but now when I turn my pc on
My gpus temp starts to go up really fast and I have to turn it off, yes the fans are running on it.

The screws are there to ensure that the heat-sink has perfect contact with the component's surface. You may be able to find a replacement screws, most of computer screws are standard.

Anyway what GPU do you have and where is the missing screws?

If there a re more than 4 screws on the GPU, you could use a screw from a non-critical place to replace the missing one.

Highly depends on the missing screw. If it's one of the 4 surrounding the processor, it's usually a different size to others on the less important pressure points, and definitely different to the shroud and endplate screws. There will also be different length screws, even if the same thread patterns. Most gpus today have somewhere between 20 and 30 individual screws.

General computer screws are most definitely not the same as gpu screws which are almost always size 00 to 1 Philips fine machine thread metric with occasional 5mm(?) hex. General pc screws use a size 2 Philips and have a courser imperial thread or 6/32 machine.

So I’m not sure what screws it used but I looked up types of screws that the heat sink used for the gpu and i think I found the exact ones they were called M2 M2.5 M3 Springs Screws Phillips Screw with Spring Graphics Card Radiator Bolts M2x6.8mm and. I don’t know of another screw I could use as a replacement.

Screws are cheap enough. If you can't figure out the exact size (and they do need to be the exact size and length and thread) then probably best to order a few that look about right and compare them to the screw that's in the opposite corner from the missing screw. Different vendors, custom pcbs use different screws, so there's almost never a 1-size-fits all kinda deal.
