Hello all. I have an older system that has been working flawlessly until I started messing with drivers last night.
Asus K8VSE Deluxe motherboard
AMD 3400+ processor
Creative Audigy 2 ZS sound card
Sapphire X800 Pro video card
1.5 gigs ram
XP Home Edition
My monitor is a 19" (18" viewable) Viewsonic E90FB.
Forever, I have been running at 1024x768 resolution @ 90hz. I started researching on if any larger resolutions would work, and it turns out the suggested resolution for 18 and 19" CRT monitors is 1280x1024.
So, last night, I tried switching to 1280x1024. It switched to the new resolution, but something wasn't right. My desktop was in "virtual mode" where I had to scroll left/right/up/down to see the entire screen. So, I uninstalled my ATI drivers (I had the latest drivers but did not have catalyst control center installed) and then reinstalled from scratch after using add/remove programs to remove the drivers, also using the ATI uninstall utility in add/remove programs.
So I installed the new drivers - 1280x1024 resolution worked PROPERLY, but, all of a sudden, moving a window around the desktop AND browsing the internet provided extremely laggy/choppy scrolling! Just as if you don't have the driver's installed. Also, I wasn't able to change the refresh rate out of 60hz.
So, fast forward a day and many, many hours of TRYING to tinker with my system. I have installed/uninstalled ATI drivers and Catalyst Control Center about a dozen times, trying different combinations.
It turns out that apparently I do need Catalyst Control Center to be installed FIRST so that I can "unlock" the refresh rate, before uninstalling Catalyst Control Center. So I was able to achieve the proper refresh rate, BUT I was still having the terrible laggy/choppy scrolling and internet browsing! (still am, right now - ugh!)
So I started thinking - what about monitor drivers?
FOREVER - my monitor has been FINE using the "Default Monitor" driver provided by XP from 2001. So, I doubt this is the problem. However, I tinkered with this. I tried using the othed default "Plug And Play" monitor driver provided by XP; nope, doesn't change anything.
I also tried using the unsigned Viewsonic E90FB drivers; nope, doesn't matter. They only appear to be a color profile, anyway. The Viewsonic signed drivers said they couldn't detect my monitor, so I never tried the signed drivers.
What the heck did I do? I just want to go back to 1024x768 @ 90hz with smooth scrolling and just forget about the whole thing (unfortunately, I have system restore disabled!)
Is there some sort of a driver/registry problem going on? Ultimately I WOULD like to try 1280x1024 @ 75hz if I could, but I'd totally be fine going back to where I started at 1024x768 @90hz if it meant I could browse smoothly once again and drag windows without lag.
