i got the radeon hd 4890
and my graphics keep crashing to a screen with dots & a square , i've uninstalled drivers and reinstalled but still happening.
can anyone help its driving my crazy , could it be faulty ?
 
When does it happen? Do you get a chance to get to any point in the OS?

Did you uninstall the old card drivers before you installed this one?
- there's a handy trick here to get rid of old drivers...

Go to system properties, advanced, environment variables.
Add a system variable (the bottom box) and call it "devmgr_show_nonpresent_devices" and set it to 1.

Close the system properties completely, then open it again and go to the device manager. go view > show hidden, and then check your Display adapters section. Any whose icon is slightly transparent is not plugged in, and you should right click > uninstall.
 
If its happening during gaming for example, sounds like heat issue, download and run gpu-z and tick the box log to file then recreate the crash, when you reboot check the log and look at the temps, dont forget to scroll right and check the VRM temps
 
i dont know much about computers tbh but i ran gpu-z this is result when i started it and when it crashed when i was playing wow.
hope you can understand this.

the numbers look fine actually, not a problem as far as I can see
did you run driversweeper in safe mode after uninstalling to make sure you were rid of any traces? before re-installing, make sure youre using the latest drivers from website, if its still happening then yeah only thing I could think of is faulty card
 
Well, if its a faulty card or otherwise called a dead chip, it will show you artifacts on the boot screen as well. If not, there is a higher probablility of driver corruption.

As advised earlier, use driver sweeper to clean any drivers present for the graphics card. Reboot. Go to safe mode, do a registry sweep. Reboot.
And then reinstall the latest drivers and reboot. U should be good to go now.

Does the crashes happen in all games or only a few specific games?
