"RETURN from STAND-BY" problem finaly SOLVED !!!

I have K7SOM motherboard with integrated SiS 740 Host/Memory controller with high quality 3D graphic accelerator (AGP 4x).
I forgot to tell you guys that I updated graphic card drivers through the Windows automatic update, two days ago.
The main problem was in updated display drivers... There is a driver Date: 30/10/2003. I just did ROLL BACK Driver in Device Menager under Display Device section, 'cause I'm sure that everything was working wonderful under old drivers... After Windows rolled back my old display drivers again, stand-by function is working great again, exactly the same as it does before. I tried to install new display drivers again, just to check, to be 100% sure, and guess what ? Same "Return from Stand-by" problem again... black screen, but I can hear my windows default sounds if I click somewhere on screen... So definitely, problem is in new updated display drivers...
Does anyone knows is there any way I can report somewhere to Microsoft or to someone else that issue (problem) with new drivers ?
