Solved System crash with screen distortion and grain

July 6, 2011 at 19:56:06
Specs: Windows 7, Core 2 duo / 2GB

I use windows 7 ultimate x86 and my comp specs. are - 2GB of RAM, 256MB Nvidia8400 GS graphics card, Core 2 duo processor, Intel D945GCll mother board and 250 GB of Seagate hard disk

On the 5th of July, when I was browsing,the screen suddenly got distorted and my system hanged.I also observed blurs and grains on screen. Inputs through keyboard and mouse were unresponsive and therefore, I had to restart the system using the restart button. Luckily, after the restart, everything was working fine.
Through the event viewer, I retreived the following,although I am not able to understand them-

I also installed win debugger and opened the crash dump file.

But I'm not able to understand anything the debugger shows.
The same crash repeated today,again while browsing,but the mini dump file was not found.

The first crash occurred on July 5th at 5:55 pm
The second crash occurred on July 7th at 6:00 am
Both of them occurred while I was browsing.

I really need to know the cause for these crashes. Please help.

I suspect v-card or ram, use memtest for testing ram. Try to reinstall v-card driver(un-install then restart the system and install new driver), obtain v-card driver from nVidia website.

I tested the RAM--- 2 x 1GB, and no errors were found. I have also reinstalled the latest graphic drivers. So, lets see what happens next.
I'll report problems, if any, here.

The same problem occurred again, even after reinstalling graphic card drivers. The RAMs are in a good condition as indicated by MemTest86. I guess the problem is with the graphic card. How do I troubleshoot the graphic card? Can I remove the monitor's connector from the graphic card's port and plug it to the one provided on the mother board?
