this is a very common problem for vista x64/dual screen users (been ongoing for months well before 4800/cat 8.7s). no sign of any fix coming anytime soon either.
but i haven't really heard of any problems using single screen......

No problems for me, I'm on the official 8.7's.
Vista 64 bit, sp1.
It has been a problem with vista under dual monitor setups since first installing it, can happen whilst gaming, regular apps or watching movies, quite random. I believe nvidia users have also had this problem so its seems to be a Vista issue.
With only 1 monitor plugged in I've never had a crash.
Exactly the same happens to me, frankly i'm not really impressed at this card so far :/I keep getting a black screen for a couple of seconds with this 4870 on Vista 64-Bit, then when it recovers i get the old "Display driver stopped responding" message.
This mostly happens with games, but it's even happened on the desktop when idle.
Temps are fine, around 60c. I've tried using 8.7 BETA and 8.7 Final drivers, Tried just installing the Display driver, no CCC. Didn't help. Even done a new Vista install, with nothing else installed but the updates, SP1, and latest DirectX version, but it still happened.
Also tried underclocking the card and using a diff card BIOS. Still didn't help.
Also used a MultiMeter to measure voltage on the cards power connectors while a game was running, no problems there.
Other graphics cards are fine in the same system.
Does anyone else get these problems? it looks as if it's the drivers...
Getting this occasionally here. 4870 with Vista 64 and dual monitors. Annoying.
these cards suck tbh... ati banging out cards that do good fps but run like crap in reality choppy in games even @ 60fps and black/blue screen city drivers
you what? stop trolling every ati 4xxx related thread.
Anyway 8.7's here on vista x64 and no problems. I did have problems installing them though even on fresh install (driver wouldn't load up after restart), dloaded the driver package and ccc seperately and that sorted it (instead of the all in one). May be worth uninstalling, cleaning and then trying that.
i have no problems with my 4850, single monitor under vista 64/32 & xp im using 8.7 hotfix drivers on all 3 os's.
your talking crap thb..these cards suck tbh... ati banging out cards that do good fps but run like crap in reality choppy in games even @ 60fps and black/blue screen city drivers
your talking crap thb..
theres nothing wrong with these cards. but if u really like nvidia cards why not just buy one. theres nothing stoping u. just stop put ing ati cards down...
