I keep getting flashes appearing across my screen playing games like Counter-strike, the only way i can solve it is running a refresh rate of 60hz. This is fine but with a 17 inch monitor it doesn't do your eyes any good. Does anyone have a clue how to solve this? I think it may be something to do with my bios, but i'm not sure. I can't understand why it doesn't flicker in 60hz whilst it does in any other mode. I have installed loads of different newer drivers but each one fails. I really want to find out what is doing this and stop it, so any help would be greatly appreciated.
