Windows 7: stupid "out of range error"

i keep getting out of range error/funny color weird bars on screen
when playing games.. even though im runnning my games 0n 1680x1050..
sometimes thishapens only in certain level/area of a game..
what should i do??? my monitor is 1680x1050.. when i run games on lower resoultion it works but is ugly..



system specs:
motherboard: GIGABYTE GA-EX38-DS4
memory: Mushkin DDR2 4096MB (2048MBx2) 800Mhz CL 5-5-5-18 SP
graphics card: Club3D ATI Radeon HD4850 512MB PCIe
Power: Enermax Pro82+ 525W
processer: Intel Core 2 Duo E8400 Box
screen: Intel Core 2 Duo E8400 Box

I know this is obvious but its because the game is changing resolution by the sounds of it OR it could be the Hz of your monitor and the game maybe is putting upto something like 75-80Hz when you need 60Hz?

Can you tell us what games your playing and the in game settings for these regarding resolution and Fequency?

for example i put borderlands on 1680x1050 60 hz and it still gives me that error

ok then

What monitor do you use? Can you give as full model number as possible so i can look up some specs for it please?

Also just update your graphics drivers, even if you already have done so, just so i can rule anything like that out. Out of interest, you havent like got any custom settings for your graphics card in game or anything through your graphics card control panel at all that might be causing issues?

So you know, i dont know whats wrong yet, but im trying to get information to help.

Asus 22" VK222U 2ms LCD its in my system specs..
and i messed aroud a bit with the grahics settings in the catlyst control center..
but i remember having this problem in assasins creed a few days after i bought my comp and before i even touched those settings..
i updated my drivers again.. no luck

strange thought but could it be your screen is turning off after say 10-15minutes because it thinks the computer is idle?

my screen if left (and before it actually turns off) displays the "no signal" screen for about a minute then turns off.

Maybe windows doesnt recognise when your in games or something and so you think its the game but its actually windows?

All that might fit unless your now going to say that it happens on EXACT levels and EXACT times all the time?

here's and example..
i used to play assassins creed, and at one assassination i always happened..
then after a while it just happened the second i started the game..
same with borderlands.. if i loaded up a a certain area it always happened.. now it happens everywhere..

could your screen itself be defective
maybe your video card is outputting more the it should for whatever reason

When its displaying this error, does it look like the screen is changing resolution or just switching off?

Also does it ever at all happen when not playing games? Reason I ask is that if its ONLY games that do this and no other full screen apps (even things like movies) then we can start to pin things down like DirectX problems and stuff like that, not to say that DirectX is the problem though, its just an example.

never happened with a movie. or any other thing except a game. + sometimes it dosen't display an error
sometimes it just shows bars of color they vary sometimes bluegreen sometimes pink blue.. sometimes black white
