Hi! Don't know if this is the right place to put this (was a toss up between this, video, and monitors)... Anyway, I have a not-so-serious but still irritating problem that started happening only 2 weeks ago.

On random occasions, when I turn on my PC, it suddenly goes into a 1024x768 resolution. I always work with 800x600 and take note that I turn it off in 800x600. I just dont know how it could become 1024 when I dont even change the display properties. This never happened before.

Could anyone help me on this (to find the cause and how to remedy it)? thanks!

If you review what programs automatically start when you boot up the PC, do you notice any that might interact with the display properties?
To see what programs auto-start:
Click start->run... and type msconfig in the textbox. hit enter.
when the config manager opens, click the startup tab.

Although not in high resolution, does similar behavior also occur in safe-mode?

Adding to jhsmurry's post, do you play games and/or use the Catalyst Control Center?

I forgot to ask if you had anything in the startup folder, located here:
C:\Documents and Settings\All Users\Start Menu\Programs\Startup
(or just click start->programs->startup)

Firstly, give microsoft update a go. Install all critical updates. I've read that one of their patches (at some point) did address erratic resolution issues.

Also, you might want to set up a separate login than everyone else (if you dont have one already). That will help preserve your preferences.

Once you have your own profile, go back to msconfig and uncheck startup items (but keep avgnt active) that are located in the HKCU hive (in the list, they are marked as such to the right). Reboot to see if you want to keep it it or not. Many of them look like non-critical updaters and notifiers. The only entry I see there that you should definitely keep active is avgnt because it relates to your antivirus program.

Lastly, the startup entries NvCPL, Nwiz and NVMCTray all relate to your nVidia video card. I suspect they are probably HKLM ("for all profiles", in other words), but you could try disabling those temporarily to see if one of them is the culprit. Remember that disabling them might mean you will lose the ability to do other video related tasks (like games, for example).
