Hello I have played since beta / headstart had the same client installed never ever craahed.
Upgraded my HDD to a 120GB SSD and doubled my ram to 8GB and did a standard reinstalled just the same as the other 4 pcs i have built myself and as i have done on a number of ocasions.
Now everything is updated new drives the lot other games working fine zero problems.
Installed STO and not only dose the whole game screen flash in full screen mode but in window mode the game runs fine for a good while but seems to crash over and over and stiupid stuff. Opening inventory, opening Transwarp window.. no real pattern.
I have never had this before in all the time I have played STO but this is the first time I have had to do a fresh install.
Well I have been messing with my ingame settings I have a 24 ins widescreen monitor and for some reason on certain "Hz" the whole screen flashes. I have found a setting that it dose not do this on now so I am once again running the game in full screen mode, will see if the game stops crashing now.
