New HD 6950 causing orange screen crash! Huh!

[Ona Island Ina Sea]

Hello,
I recently installed a new XFX HD6950 replacing an XFX HD4890 and I started to have crashes first to a screen with 1/8th inch wide white vertical stripes with dark pinstripes and lately to a solid orange screen. It dosen't respond to control/alt/del, but does reboot back to Windows in normal mode. The GPU does not get over 43 degrees. I got the latest drivers for the GPU from XFX when I installed it, not bothering with the disc. I have run all the diagnostics in Win 7, Microsoft Fix It and a memory test but nothing works. Only thing I can think of is a driver conflict with the old HD4890 but not sure how to check and remove.

Any suggestions gratefully accepted

Get the latest drivers from AMD.com.

Thanks for the suggestion, but the drivers from XFX are the same version as from AMD.com.

ver. 8.861.0.0

have you removed the old drivers with driversweeper? you should do this especially when upgrading from one card to another.

Hi iam2thecrowe

That's the suggestion I got from XFX support so I'll try that and let you know how it goes and I'll give you best answer if that solves my problem.

Thanks
