So, then I tried using the Device Manager's option for searching for new drivers on the internet, and it returned the mesage that my current driver is up to date. What I don't know is if I can really trust the Device Manager's search, ya know? Especially since I finally found this at the Dell site:
ATI X1300 Pro
Release Title: Video: ATI 128MB Radeon X600 SE, 256MB Radeon X600, 256MB RADEON X850 XT Platinum Edition, Hyper Memory PCI-Express X16 (DVI/VGA/TV out) Radeon X300 SE, Radeon X1900XTX 512MB, RADEON® X600 256MB HYPERMEMORY, X1300, X1300 Pro, X1300 Pro 256MB, Driver, Windows Vista 32-bit, Multi Language, Multi System, v.8.383_Leg_WHQL_070613a-049454C-Dell_Vista32, A04
Release Date: 7/9/2007
Description: Latest 8.383 WHQL Vista32 Driver from AMD.
I know squat about drivers, but this appears to be the one I'm searching for, yes? According to the Device Manager, my current driver's release date is 10/24/2006, and driver version is 22.214.171.124. (What's with Dell, anyway? I bought this machine in April 2007. Grrrrr.)
The reason I'm so intent on finding an update is that I appear to be having screen rewrite problems (can start a new thread on this and post a pic if need be). A friend
suggested that I might need a better card, but I thought I'd first see if a driver upgrade was available that might do the trick.
Thanks to anyone who read this far.
