ViewSonic VG2230 monitor
8800GTS 512MB (not the new G92 core)
P5K deluxe mobo
normally my resolution is 1680x1050 but today i turned my computer and it's changed to 1024x768. when i go try to change it i only get 2 options:

i've had the same drivers installed for months and no problems at all. i uninstalled, then reinstalled the latest video card and monitor drivers (i already had them installed before the problem). problem still persists
the monitor shows up as Generic Non-PnP Monitor in device manager. dono if that's normal or not
yesterday i didn't change any settings or install anything, i just did my normal everyday routine
sooooooooo i'm out of idea's except maybe install some older drivers?
