My XFX-HD 4350 on [COLOR=blue !important][COLOR=blue !important]Windows 7[/COLOR][/COLOR]
32bit was working fine with ati catalyst control center latest driver
mistakenly 'Overdrive' GPU and RAM sliders moved forward upto full high by me manually, Catalyst Control center application tested new settings few for minutes ( not given me chance to cancel) then screen freezed with color snow over the normal desktop display. Perhaps ATI memory/GPU clock [COLOR=blue !important][COLOR=blue !important]rate[/COLOR][/COLOR]
mismatch, too high.
restarting PC: everything boots normal, till [COLOR=blue !important][COLOR=blue !important]CCC[/COLOR][/COLOR]
application start from startup, same problem happens.
I used selective startup and disabled CCC from startup options. Then sytem is OK as usual but CCC application doesn't start.
Tried to uninstall all ATI drivers
and applications and then reinstalled, nothing helped. When CCC starts, it reads same values of overdrive and screen freezes.
Currently system is working fine without CCC. onli display driver of ATI.
I wish to have CCC functional, because I had enabled overdrive upto safe extents and it was fine earlier, wish to get it back. Q. How I can reset this CCC overdrive to normal or previous ranges while I can't even access that configuration screen because when ccc starts, it freezes. I have already tested re-installing whole ATI suite.
