well not completely. i seem to have broken the graphics card. and something weird is happening sometimes with turning it on. today the power button worked fine, but previously i've needed to hold it down for a few seconds.
in my foolishness and hubris i thought i would be able to remove the heat sink and clean the fans and then put everything back and nothing would go wrong, for sure,
haha
silly me
at least the fan isn't making a horrible noise anymore
