I just had a budget system built with Asus M4A78LT-M LE motherboard which comes with integrated graphics Radeon 3000. This board was manufactured on Jan 2011 with Bios version 0704. I installed windows xp and all the drivers. The problem is the videos(movies, youtube, everything) play pixelated and grainy on my 17inch Samsung crt monitor. Connected to another monitor(tft), same problem. Downloaded and installed new/old drivers, no change. Yeah, i installed and uninstalled k-lite codec pack, used driver sweeper to remove leftover drivers, no solution. I played in different video players, changed vlc's video output to direct 3d, opengl, etc.. still pixelated.
Even the screen itself is not as clear as my 10 year old intel 815 graphics, looks kind of washed out. I am searching a solution from two days, haven't found any.
Is there problem with integrated gpu hardware? What should i do now?

I've tried all those tweaks, not a single setting has helped my problem. The desktop itself looks very inferior compared to intel 815 graphics.

Post your detailed system config. I guess your CRT monitor is directly connected to the VGA port.

aren't the drivers which ship with motherboard supposed to work for basic stuff like video playing etc... I will try Catalyst 11.5 but the integrated card itself is quite old, so i doubt it will help. I have already tried few other versions, none have helped. Everything has been so dull looking in this computer so far.

UMA frame buffer size in Bios is set to Auto. Adaptor information in windows shows memory size 700mb.

Other than the videos, the graphics quality itself looks like compressed jpg image.

I think northbridge/igp has to be the motherboard temperature right?
Motherboard temp - 34 c
cpu temp - 39 c
vcore voltage - 1.392 v
3.3v voltage - 3.296 v
5v voltae - 5.120 v
12v voltage - 12.099 v
cpu fanspeed - 3292 rpm

I think in most of the CRTs the VGA cable is permanently attached. OP has also tried on a TFT monitor with similar results. Looks like either a corrupted Windows installation or some hardware problem.

yeah monitor issue is ruled out. my crt monitor has permanent vga cable which works fine with external tv tuner box giving clear videos.
i am installing windows 7 tomorrow to confirm if its a hardware problem.

I installed Windows 7 and still face the grainy display problem. Both in winxp and windows 7 i get a 0.25 sec synchronization problems in videos plus the pixelation/grainy playback. The problem is definitely the integrated graphics hardware.
I heard complaints of the distributor of Asus, rashi pheriperals purposely don't RMA. I'm sure my vendor will handle this case but should i attach a letter describing the problem and how long will they take to give back a new motherboard?
