Ok so i've started to notice this problem with my new gaming rig, seems to sometimes not happen for hours, sometimes every few seconds. I basically get a black line flash for less then a second, they kinds cover a third of the screen or so and are diagonal, shapes and timings being random. Got really bad just now but didn't notice it at all yesterday i am playing the same game though.
What could the problem be? I assume it's GPU related, it can't be temps cos i did the fan speed change thing and now my 4870 is running really cool. I also updated the driver which i think went successfully, used drivercleaner and all that.
any ideas what's wrong?
oh and if it's related my 17" monitor is quite old, we got it five years ago and i believe it has a 16ms refresh rate( is it refresh rate which is recorded in ms? 2ms being the best usually?), could the game be refreshing the screen too fast for the monitor, lol i'm just throwing out ideas i guess it probably is GPU though.
