weird problems when playing paticular games

ok i have a resolution problem.. i'm running all games in 1680x1050
but with some games i cant run them on that i have to lower it to 1280x1024 or something.. beacues it does funny colors or gives me sometimes blue screen of death.. or says "out of range error" it dosen't make sense i'm running the latest drivers...

Hey. Too much heat is my guess. See if the same thing happens with a large fan blowing inside the open case, as a test.

Do you have a link to the exact card you have?

are you sure too much heat can cause it to display
"out of range error"
coz i dont think so..

i have a radeon ati hd4850 512mb memory

Out of range error is usually a monitor issue, it would also help if you filled in your specs fully.

i filled in system specs

please guys i need answers

Hey. Have you tried the fan suggestion already as a test? That is a factory overclocked card without a really elegant cooling solution like full card cooling as you would find with many other factory OC cards (like mine.)

I still think heat may be a factor.

i tried it did not help..
