ATI 5850 monitor goes to standby

[milkamil]

This is really ****ing me off...

During playing games like rFactor/CoD MW2/others (but not all) my monitor suddenly goes black, then the light change to amber like in standby (and info from the LG monitor that it's in a power saving mode - same like when I turn off my PC), I still can hear the sound of game, shoot/drive so the PC doesn't freeze, just the screen is "off". I made a this topic to see how many people also have this problem. Is it a drivers problem, or my card is fcked? I googled for it and I found that many people have this problem, not only with 5800 series, but also some older 3000/4000 series. Is there any known solution for it?.

Sometimes screen comes back to "live" after 20-30 seconds, sometimes it doesn't and I have to reset my machine.

I've never had this before, I've had HD4850 and Vista 64bit SP2, now I'm running Win 7 64bit with 9.11 drivers, on 9.10 was the same. I've tried to turn off all Windows power saving/hibernation and all other crap options but it didn't help. It happen with and without OC.

Please help Sry for my bad english, I'm just bad foreign mthrfckr who spend £200 on ATI card that gives me only troubles!

First 3 things that spring to mind...

1) What power supply have you got - is it the one in your sig? Maybe it's drawing too much power for it / or is developing a fault?
2) Is it overheating?
3) Is there any mention about ATI VPU recovery?

My computer did exactly the same when I was running my 3850 AGP on a 200-250W(memory fails me) power supply.

TF2 was pretty good at causing it to do that.

Power supply was hugely underpowered for it *_*

1. Yes, it's Tagan U33 2-Force II Series 600W. Where can I find if it's developing a fault? I never had problems with it, and it's pretty good PSU
2. Nope, I tried running GPU on 40% fan speed and max temp was about 60-65 and this still happened
3. Sometimes I have "Display driver atikmdag stopped responding and has successfully recovered" in event viewer, but not always when monitor goes black. So it might be something about it, but not always.

I doubt that my PSU is causing this problem, I was running HD4850 before without any problems.


My Tagan have two PCI-E 6+2pin connectors, but with 5850 came two Molex-to-6pin adapters, do you think it might make any difference if I connect through them instead of the original PSU PCIE 6pin connectors?

Not sure (short of getting a multimeter out or a proper PSU tester) if you can.
The temps certainly suggest it's not overheating, and the VPU recovery is not consistent with the problem.

I too went from a 4850 to a 5850 and my Antec 550w failed within a few days.
I was no-where near overloading, using roughly 400-450w peak so had a fair bit of headroom, but as anyone will tell you that it's not always about total pull from a PSU, but it could be that a particular rail could go - as did to me.

I'd try another PSU if you can get hold of one and see if the problems carry on.

I found my old topic on google somehow ;]

Catalyst 9.12 fixed the problem, so it wasn't PSU fault, just the drivers...
