Game Has Lots of CTDs (Crashes) Now

Never had a single one before. But in one day of gaming. (a few hours really) the game froze, and then either forced me to forceclose or hung so long the computer did it for me. Putting me back on desktop.

Never happens during gameplay, but ALWAYS on map change...so I think it's server or loading related.

Same on the map change crashes.

for me you vote, then when voting finishes it takes you to a blank operator selection screen and it just sits there until I press a button on my keyboard and then it crashes. Is it loading but without the loading screen?
