hello, 

I have radeon 6990m.

windows 7 home premium 64 bit.

tried on 13.1 and 12.8

2nd Generation Intel® Core™ i7-2720QM Processor ( 6MB L3 Cache, 2.20GHz)

2nd Generation Intel© Core™ Chipset HM65

I thought it wouldnt be so stupid to try and overclock by just 10Mhz..I was wrong..

now every time i start my computer i get black screen after windows logo.

I tried to go into safe mode and disabling the adapter, go back to normal mode and remove catalyst ith all the drivers using DriverSweeper and reinstalling everything back.

still no luck.

is there any one who's familiar with this problem and can help me?

You use System Restore, failing that you reinstall Windows or use your recovery disk.

Sounds like an AHCI issue to me,, when i installed my Win 7 i had AHCI disabled in the bios and didnt realize till later,, when i changed to AHCI then win 7 wouldnt boot up it would just go to blank screen like your talking about i followed this tutorial http://www.sevenforums.com/tutorials/61869-ahci-enable-windows-7-vista.html?filter[2]=Performance Maintenance

and all was well again :wink:

Also if your motherboard has on board graphics try to remove your 6990 and boot from the motherboard,, if that works while your in there uninstall all your ati drivers and run a registry cleaning tool and reboot , then shut back down and put your card back in and see if that fixes it or not.

Good luck
