6990m overclock failed

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?

    how? i cant get into CCC cause' it needs restart after installation..and then the cimputer doesnt start.
    safe mode doesnt allow me to do that because it uses it as a generic vga
  9. use driver sweeper.
