Help needed!i got some really weird problem

hi!so guys,my problem is that im running this game on my pc The burning crusade one,and so i can play the game on 110-130fps outside,and in the citys between 30-50fps,no lags no freezes.But whenever i logout from the game into the menu where u can change characters after several seconds the games just freez,and i have to restart my pc.I have tryed to update my graphic cards driver to the newest,and it was even worse now im using a driver from 2012.Its better but still i get this freeze.I also have GTA V installed and there is everything just fine playing it on 1920X1080 resolution without any issues.
My graphic card is msi geforce gts 250 1gb ddr3 twin frozr.Now im thinking about that,that my power supply can be a problem but still i dont get it why GTA runs without anything weird to happen while this game which is from 2007 giving me problems.

Try enabling vertical sync in options -> video. That way your fps won't go over your monitors refresh rate. Without it my character selection screen on tbc reaches 1000 fps, which could cause problems in some cases.

thank u sir indeed i have been disabled it.Will try,if it helped im gonna reply back to this post

Amazing,it worked no more freezes,thank u alot sir,i cant describe now how happy im it was rly irritating having those freezes.bump
