Hey thanks for checking out this thread.

I've been having a lot of trouble as of late with my new graphics card. The ati radeon hd 5670.
For a while it worked pretty well but after attempting to update the drivers a couple weird things started to happen.
The resolution on startup would set itself to 720x480 and the only way to set it to something ELSE was by using ccc.
Going into the regular windows display didn't give me any other options besdies 720x480.
I've attempted to delete drivers, rollback, and I just finished reformating and reinstalling everything.
I can set it to it's normal resolution but the minute I enter a program that would change the resolution it's back to 720x480 or even lower.
It hasn't overheated, i've kept a close eye on it's temp and it's never gone above 58 c.
Could it be a defective card? I have no idea but since i've only had it for a week it should be under warranty.

hd 5670
xp sp 3
asus m2n-e
2.0 gz dualcore
4 gigs of ram (only using 3.4 because of xp)

If you need anymore information please don't hesitate to ask. Any help would be appreciated  Try reinstalling the drivers that shipped with the card...
That being said if it still acts up i'd exercise your warranty...Ya I tried using the drivers from the cd that came with the card. Caused a blue screen actually o-o which was rather strange. stop c0000la fatal system error =\ sounds bad
I did install the latest from the website which I had no PROBLEM doing. Besides the current problem that is.I'd return it tomorrow...No other ideas huh? Well alright i'll return it. Thanks for the help.
Edit..
Well I somehow got it to save the resolution to 1980x1080 but it still won't let me set it to above 640x480 in game.
It ALSO looks like I could play games windowed if I manually set the resolution through the launch options but the second I hit fullscreen it's back to 640x480.Update: Well I attempted to play a game the card should easily be able to run and was getting less than 10 fps. So I am going to go with you being right about the card.
I'll return it later today. Thanks again for your help.No problem...

Best of Luck with the new one.Well after a couple weeks I finally got my replacement card and nothing has changed. I'm.....out of ideasCan I ask where you got this card from?

have you tried using driver sweeper and installing again from the driver CD that came with the card?
http://www.guru3d.com/category/driversweeper/Ok finally got it to work. All I did was completely ERASE everything ati related and install from the cd. It seems, for some odd reason, that I literally have to stick with the drivers from the cd or I START having problems. I attempted to update to the latest version and the same problem I had before started again.
I got this card from newegg.com but it seems to me that most of this is just my mistake.
So I guess this is sort of solved.

Sorry for wasting your time with something that was my fault.Newer drivers are not always better drivers...

Glad to hear you got it sorted.
