Hello, I've been having some trouble with my GPU the past couple of days... At first I used to lose video signal while I'm gaming, it was causing a lot of trouble. So I decided to take out everything out of the case and test the system, the problem seemed to go away.. no more crashing while gaming etc. But I still face a problem, when I boot the system in the morning, it takes too long for the motherboard to POST ( aka give its first *BEEP* ), takes around 1 minute or so (during the time the monitor is still on stand-by mode), then I'd get kind of weird looking white-dashes all over the screen in bios ( yet i can use the system just fine but it cant enter windows ), after one more reboot everything goes back to normal. This problem doesn't happen on each boot, it sometimes happens, sometimes not. It's really confusing, now I don't get any problems while I'm gaming, I did 3dmark06 benchmark and it gave me around 17k points.. I played hours of NFS Shift without any problems.. So I'm not sure what's the faulty hardware here, could it be the motherboard or should I blame the 4870x2? ( I'm pretty experienced with computers but my heart tells me that the video card is fine, i feel something is screwed with the mobo, although all the problems I'm getting is video related ) Mind you, no heating issues, everything is running cool here, max temps for the 4870x2 are 85C and I keep monitoring the temps the whole time I'm using the pc. http://www.dailymotion.com/video/xap3g2_gpu-problem Here is a video describing the problem, sometimes these blue stripes show, other times white dashes show at POST screen.
