Ati 6850 - Problem

[Guest]

HI , I have recently upgraded from a ati hd 3450 to a hd 6850 , everything seemed to work well the first day , and some of the low overclocking i did went fine , the following days all started to mess up , i restored the custom clocking ot normal , as i though that was the case , the screen twittered , and black lines flashed until the screen crashed , that was fixed after you rebooted the computer , no games could be played as they got stuck and a little triangle shows up with an exclemation mark in th windows bar. what could be the problem ? i reinstalled the driver but that only helps for about a day , ohh and while watching pictures , you can see red and blue pixels moving around,

might be an overclocking failure,i would say to reset bios chip.another thing that you should consider that overclocking sometimes does makes system completely overhaul.
