In the past couple of weeks my iMac has not been running properly. First it started with getting a lot slower than it used to be, continuing with loud, really loud fan noise (even when starting up the iMac). After I had resolved the issue of the fan speed the computer wouldn't start up and showing me, also knows as ''The White Screen of Death''. Trying to fix this by booting the Mac in Recovery Mode and trying to reinstall MacOs it helped me getting into my account after which my computer was extremely slow, at the point I could not do a thing.
Therefor my question, has anyone experienced this before, and if you did, was it resolved by upgrading to an SSD? I have no clue how to fix this problem and I don't feel like spending a whole lot of money on a new iMac.
Thanks a lot
