I took my graphics card apart today to replace the thermal compound. It was getting too hot and the fans would always spin up really loud. Everything was fine until I started putting it back together and the really heavy heatsink fell straight onto the card itself.
Now it's broken. It loads up but crashes games, and causes blue screens of death.
It was not a cheap graphics card, and will not be cheap to replace, especially since graphics cards are currently ridiculously rare and expensive.
I am suitably not happy.
