I'm no PC expert, but I've installed or updated video drivers several times, wasn't too worried...
Okay, I thought, updating this Browser_PC's graphics to OpenGL 2.0 drivers will take a modicum of care: Turn off the cable modem, shut off Norton's, use Control Panel to un-install old Nvidia ForceWare, install the new version plus the GeForce4 drivers...
Control panel, un-install Forceware, so far so good. Gotta reboot to complete un-install ?
Yeah, yeah, okay. I'm not bothered by a couple of re-boots, not after the time installing Norton's took 17 re-boots punctuated by two hours of hefty LiveUpdate down-loads-- Via Broadband, yet !!
Okay, bloop, off it goes... Bloop, up it comes-- In lo-res ??
D'uh ?
Then the pop-ups began: Found new hardware, no driver found. Found new hardware, no driver found. Found new hardware, no driver found...
From those I remember, it had orphaned the CD drive, the 'extra front ports' USB card, the USB link to CAD_PC, the ethernet interface, the mobo's sound, the graphics card, the scanner, the label printer, the web-cam, the laser printer, the USB sharer...
By that point, I was feeling quite ill.
Sure, I've got all the disks, but it was 23:30 local, and I *really* did not want all this grief...
Fortunately, I'd set a System Restore point before playing with those OpenGL diagnostics utilities. That was Plan_B. Control Panel had done another for the un-install. I've never used Windows XP 'restore' function before, was rather nervous as the process began.
Um, it works: I'm posting this instead of banging my head on the desk, aren't I ??
Be careful, especially with Nvidia ForceWare and drivers !!!
