Vista - Monitor Resolution problem..

Hey guys new here.. i am currently running vista ultimate 64bit, i recently made a new gaming desktop computer.. the card im using is a inno3d gtx 275, anyway the problem is that sometimes when i reboot the computer my reso changes to 1280 x 960 which does get frustrating at times, i set it to 1440 x 900 normally but it changes after vista loads which is annoying (inconsistently) .. basically its like it doesn't save but its also inconsistent, sometimes it works fine other times i need to change the reso back manually.. hopefully we can get a fix here!..

The monitor is a 20" samsung p2050 syncmaster, i have downloaded the new monitor driver, also the new nvidia driver for my card, i have even tried the other dvi port in my card as it has two..

Hey guys i kind of know what the program is but i don't really know a "fix" yet, I play this game team fortress 2 and it seems to be the problem, if i play it and then reboot the reso automatically changes too 1280 x 960 (which is the setting i don't want ).. now if i change the reso in the game to lets say 1024 x 768 and set my windows reso to the same the resolution stays the same and doesn't change by itself.. but the thing is the reso in windows is quite ugly and the icons are quite big for my monitor.. if there some way or option to disable the game doing that or something? - Jim
