Ialmdev5.dll the sims 2 blue screen

hi...ive had the sims since it came out, and i have the open for business, glamour life, h&m, and pets expansion packs. i have downloads for the game too. recently whenever i try to save, a blue screen comes up and says:

A problem has been detected and windows has been shut down to prevent damage to your computer.

if this is the first time youve seen this stop error screen, restart your computer. if this screen appears again, follow these steps:

Check to be sure you have adequate disk space. if a driver is identified in the stop message, disable the driver or check with the manufacturer for driver updates. try changing video adapters.

check with your hardware vendor for any BIOS updates. Disable BIOS memory options such as caching or shadowing. if you need to use safe mode to remove or disable components, restart your computer, press f8 to select advanced startup options, and then select safe mode.
