In order to help you, we need to know what video card/chipset you have. Can you open Applications > Accessories > Terminal and type in lspci and hit enter. Copy and paste what results into your next response. Also, can you please describe the flickering a little more.

Ah Ha!

00:02.1 Display controller: Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller (rev 03)

That is your video chipset. You have an Intel Mobile Graphics controller. Many people have been having problems with 9.04 and Intel video chipsets. Check out this thread:
