Last night my screen suddenly black out after a series of unstable flickering.
My config are as follow:
Intel Core 2 Quad Q6600 2.3Ghz
Windows Vista Ultimate 64-bit
ATI Radeon 4870
The system has been running for over a year, and this is not the first time that the screen black out, but it will always recover within a few second. However this time it does not recover.
I have gone through to safe mode and start windows with lower resolution to CLEAN re-install the newest driver but the problem still exist.
As I have a wide screen 24" monitor, It will run normally with "wrong" resolution (not porportion to the screen size) however everytime i tune the resolution to the right proportion (i.e. 1920 x 1200, or even 1280 x 800) it will black out... It runs normally at 1920 x 1080 tho.
I have tried speed down the graphic card memory from 900mhz to 855mhz but it does not help.
Please could anyone help me with this!
