First of all let me thank you for any information on this matter, while I was playing a video game the screen suddenly froze, I wasn't able to do any other action other than a hard reset.
However when my PC restarted, the screen was displaying this strange horizontal lines across it:
To which after a minute seems to crash or just freeze completely, so I'm not able to disable the driver on a normal boot-up:
I can use the PC on safe mode, disable the driver and boot-up normally without the driver (uses the standard VGA card). But whenever I manage to install any of the AMD Catalyst drivers the lines appear over the screen, sometimes causing a BSOD (haven't managed to get the error code yet as the BSOD is very random).
My PC is a DELL XPS 8500 with Windows 7 Service Pack 1, the graphics card which it comes with is the AMD Radeon HD 7870.
I have asked on different other forums and this is what I have tried so far:
- I have tried installing the driver available from DELL, even after using a cleaning tool for the previous drivers it all ends the same way.
- The AMD auto-detect tool recommends the AMD Catalyst 14.12 Omega Win 7 64-bit (I believe this is the latest beta version), issue still happens.
- Uninstalled and installed a previous version of AMD Catalyst, the lines are still appearing and then the screen freezes.
Sorry for the long post, not sure if anyone can help me with this? I really hope it's not a hardware issue, I still have the warranty but many people have told me that this is a driver issue?
Anyway thanks in advance!!
