Display Driver Has Crashed- Acer Aspire

Hey guys,
I have been having this problem for a long time now. I have done my research and the solutions that other people had didn't really seem to work for me. I have tried reinstallling the display driver, formatting the computer, updating the driver, i even bought a new ATI display driver. If you guys can help me it will really be appreciated. Okay so this is what exactly happens. I would be using my computer normally then it would freeze up, the screen would go black. Sometimes it would go to a BSOD and i have to restart, sometimes it doesnt come back, and sometimes it does comeback. When it does comeback a little message pops up saying "Display driver has stopped responding and has recovered" It is really Starting to annoy me.

MY PC INFO:
OS: Windows 7 Ultimate (x64) (build 7600)
CPU: 2.00 gigahertz Intel Pentium Dual
HD: 309.59 Gigabytes Usable Hard Drive Capacity
System Model: ACER Aspire M1640 R01-B2
Board: ACER MCP73VE NVIDIA MCP73
4096 Megabytes Usable Installed Memory
DISPLAY: ATI Radeon HD 4300/4500 Series [Display adapter]
Screen: Acer X193W [Monitor] (19.1"vis, s/n LDW0D0168500, September 2008)

I got all this info using Belarc

From what you've described, you've done all the testing/replacement that we would have done.
In that case it's most likely that there's a problem with your motherboard and how it handles graphics.
I'd suggest a new motherboard, but that'll set you back around $100 (US) and there's no guarantee that this is the problem. If you do purchase a new mobo, be sure that you can return it for your money back if it doesn't work.

Good luck!
