I was having a problem with my computer going into sleep-mode and not being able to come out without unplugging it. So after a quick google search it looked like I needed to change a bios setting so that my computer would recognize my keyboard and mouse when it's in sleep mode. I couldn't find the right setting but that's aside the point. I also noticed a PCI-e frequency setting. I googled what that meant and my curiosity had got the better of me. Someone had recommended it be at 107 rather than the default 100, so i tried that and started my computer. From that point on I've been having serious problems. My computer is extremely slow. Most of the time after I log in it goes to a black screen with a mouse, and sometimes it'll start up fully but it'll be extremely slow and then I'll get the blue screen of death after awhile. The only thing that works is starting up in safe mode. I've tried changing that setting back to 100, restoring all BIOS settings to the default, a full virus scan, a system restore, made sure my hard drive was in DMA mode. I'm not even sure it was the bios setting that caused the problem. Could something be wrong with the hard drive? Does anyone know the problem or have any suggestions?

yeah i think its the driver for windows 7 thats the problem, or how the drivers fuctions with windows 7 or how the drivers fuctions with hdmi to hdmi cables. I heard this problem happens for some nvidia drivers as well. what im mainly trying to decide right now is if i should try buying a dvi to hdmi cable to see if it fixes it.

I tried all the different setting for my picture mode and it only changed the borders which ive already fixed, quality is still the same. As for my native resolution, its most definately 1920x1080. Im 90% sure my problem is hdmi cable or driver/operating system related. I have tried two different hdmi cables btw so the cord itself is fine, its just not compatible with my os/drivers

Im currently using a Saphire 5850 video card and windows 7 64bit, and i just bought a new Proscan 42" 1080p 120hz led lcd. The 5850 has an hdmi port so i simply hooked up my computer to my tv with an hdmi cable but the quality looks pretty bad and the borders dont line up. I did a bunch of research and i fixed the borders with catalyst control center but the quality is still bad.

According to other forums and threads it seems that its a problem with windows 7 and its like downgrading the resolution and then upgrading it making it look all grainy. Aparently this isnt a problem with vista or xp. I heard that the windows 7 beta drivers make it work but i dont think they have those for the 5xxx series. Does anyone else know anything about this issue? Would a Dvi to hdmi cable fix it?
