I am in terrible trouble with drivers
for an HP C 7280 Photosmart All in One.
The device has been working perfectly well under Windows 7 build 7000, and more lately with 7057 upgrade.
Starting with some unexplained problem in printing I tried to reinstall the driver
-I had a file sitting in my Downloads file. BIG MISTAKE!. It found that the installation I had was incompatible and said it would remove these elements (or something similar). Net result is that now Windows won't/can't recognise the printer when it i plugged in (USB), won't allow any other HP driver to install (doesn't recognise Windows 7 OS) and in some way I don't understand had the effect of slowing my system down to less than a crawl -(it took a good 10 minutes to reboot)-windows were appearing slowly like ghosts (so the nVidia GeoForce card was affected). Eventually I was forced to a system restore. I removed all of the HP files from the system I could. Rebooting was again a 10 minute job, etc. Eventually I did another system restore to an even earlier time, and at leas the system is working sufficiently for me to send off this plea for help from anyone.
How can a printer driver wreak such havoc on a system???
