I have changed my RAM to ddr2 2gb 800mhz and my mobo is intel g41rq,NVIDIA 8400GS, core 2 duo 2.4ghz proc, my graphic card was worked fine since i changed my ram. when i switch on my pc my graphic card showing cracked screen but it works on safe mode without the nvidia graphic card driver loaded and i get post screen of windows and bios also when pc starts. but when it loads graphic driver it shows the above error nv4_disp.dll stuck in infinite loop something like that. when i removed external graphic card and connected to My integrated intel graphic accelerator vga it is working fine with the intel vga driver. What is the problem? No problem with MY HARDWARES LIKE MY GRAPHIC CARD,RAM,HARDDISK,PSU and I checked with my old 1gb ram also why I am telling is. bcoz i checked all these things with another pc all are working fine. my graphic card also WORKING FINE IN THAT SYSTEM. I formatted OS completely 5 times and i uninstall and installed the NVIDIA graphic driver 10 times. I downloaded and installed the latest NVIDIA driver, I updated my BIOS, I put BIOS in to default mobo setting. Still i am getting the same cracked display when system starts to load graphic driver and after some 20 seconds it shows bsod error nv4_disp.dll i mentioned above. HELP ME PLS!!! I am doing RESEARCH about this problem for last 2 days. Still not finding the solution... What are the other things i can check i almost checked all, and my graphic card working fine in another machine ..

Cracked display means it like showing Blurred or flickered image with dots on the display that we cannot see anything. it show like that for 10-20 seconds when system starts after that it show bsod error and freeze itself.

You need to uninstall the nvidia driver, then reboot & let the standard VGA driver load. Then you can install the latest driver available from the nvidia site.


Why did you get DDR2-800? If your CPU runs at 1066MHz FSB, you should be running DDR2-533 or DDR2-1066. Anything else is less than optimal.

I checked intel dg41rq chipset motherboard specification it showed that i can put ddr2 667mhz and 800mhz RAM .... I think no problem with my new RAM. there is something happened when i put the graphic card in to my mother board slot. Today i will check with different nvidia graphic card and let you know whether its a mobo pci *16 slot or not.

"it showed that i can put ddr2 667mhz and 800mhz RAM"

Doesn't may what you can use, I'm telling you what you should have used. It will run as you have it, but it's not the optimal configuration. The RAM is out of sync with the CPU so you're taking a minor performance hit. You should manaully configure the memory to run at 533MHz.

The 8400GS sucks anyway, get a decent card.
