Whenever I open my Yahoo Messenger or any installed games my PC shuts down. Error says it is caused by the file nv4_disp.

Thank you Mr. Todd for the link and for replying. smile I will check it out and let my pc technician read the link as well. Best regards! – maria Mar 18 '10 at 13:25

Besides the device driver, it may be insufficient power from your power supply.

Was your video card upgraded from the original to a gaming card?

Does your NVIDIA card have an external power plug that is plugged in?

What video card do you have, and what are your power supply ratings and manufacturer?

EDIT: To find out your video card, right-click on the desktop, select Properties, Settings tab, then look at the contents of the dropdown under "Display:".
