I bought a 'B' Grade MSI 7850 Twin Frozr III here in February and over the past couple of weeks it has been showing weird artifacts on the desktop and when browsing online. Also does it playing games so pretty much all the time. Started off as just a bit annoying and they would go away if you left it for about a minute or so. But a couple of days ago it got to the stage that it became more and more frequent and worse looking, sometimes causing the 'Display Driver has crashed and recovered' message. However today, it got to the point that the desktop boots but about 2 or three minutes later the sparklies are all over the place and then *BAM!!* the screen goes blank, black, white or some other colour and the only way to restart is to reboot. Then it does it again. Things I've tried so far:-
None of the above have made any difference.
Now after the last uninstall and reinstall of different drivers, it is refusing to boot to the desktop in 'normal mode'. I can only get Safe Mode to work. If I try and boot to the desktop normally just as it should come up the screen goes black. Not off or blank, but black. No cursor or anything.
The card isn't overheating, its been sat at normal temperatures since I got it and even playing graphically intensive games it was showing usual/average temps. So I'm guessing that for some reason out of the blue the RAM on the card has gone bad? If anyone has any suggestions on what to do to try and get it working again, I'm all ears.
Failing that, I'm going to be looking at a new GPU I expect? No warranty as it was 'B Grade' - think I've learned my lesson there.
- Swapped out the DVI cable for a new one
- Tried a different monitor
- Uninstalled the ATI drivers and used DDU to clean up before reinstalling the drivers
- Tried different drivers going back over the last year
- Reseated the card
- Swapped the card from the PCI 16 slot to the other PCI slot
- On the rare occasion I managed to get to the desktop for any more than 3 minutes, I used Afterburner to increase voltage a little
- Also used Afterburner to underclock by 150mhz
