Screen Resolution Changing on Startup

[Saetana]

My screen resolution is normally set at 1280 x 1024 but since a tweaking
session a couple of weeks ago (although the timing could be coincidental)
every time I switch off the computer, when I switch it on again the
resolution has changed to 640 x 480. I have checked the tweaks I performed
and can't see how any of them could have caused it and my "save desktop
settings" box is ticked so I can't see what is causing this problem. Whilst
it only takes a minute to change the resolution back and rearrange my icons
it is now starting to get seriously irritating.

I am running Windows XP with Service Pack 3 and any help anyone could give
with this problem would be greatly appreciated.

Nobody knows what you did during your tweaking session. (Apparently, not
even you.) Uninstall and re-install your video driver, following the
video card manufacturer's directions very carefully. If that doesn't
work -- good luck.

Before your next tweaking session, make a record of all your steps, only
make one change at a time, and backup your system before you start.
