error: windows display driver stopped running

I have a Windows XP Media Center workstation at my office, It was working good since years but recently started getting an error time to time. It says:

“Windows display driver stopped running -
The ialmrnt5 display driver has stopped working normally. Save your work and reboot the system to restore full display functionality. The next time you reboot the machine a dialog will be displayed giving you a chance to upload data about this failure to Microsoft.”

My system’s Graphic Adapter is Intel 82945G Express Chipset Family. I already downloaded the required driver form Intel’s website and installed by the error wont go. I even defragmented HDD and ran deep virus scan, nothing found suspicious but the problem still persists.

Can you guys provide some help to fix this error? Many thanks.

Intel has the latest generic versions of the graphics driver available. If you install the latest driver from your computer or motherboard manufacturer and still encounter the problem, try the latest generic driver. To locate and install a newer generic graphics driver if applicable, visit the Intel® Driver Update Utility.
