about CMOS reset - look in the manual of your Motherboard
Thank you, I am a beginner with this troubleshooting. I did a CMOS reset, kept all in default and followed all steps (except step 5 where I used AMD Radeon Crimson relive software. When installing the driver still black screen.
I have Windows 8.1 so I cant even try the new AMD Adrenaline Release 😕
Once again, thanks for the reply though 🙂
