I have an old Dell 4500s desktop PC with the following config: CPU Type: Intel Pentium 4, 1.7 GHz RAM: 1280 MB (256mb dell ram) + (PC3200 DDR SDRAM kingston) Video Adapter Intel(R) 82845G/GL Graphics Controller I am having a frequent restart whenever I open a video file. When I play a movie using window media player , VLC and others , it became black screen for 2 second then resizes the monitor resolution to 640×480 and displays everything in 4 colors 16 bit. My problem started on a day where I frequently open a .mkv file video file before the ffdshow being load up.Upon that ialmrnt5 display error everything turn into 640×480 resolution and 16 bit and since then it shows frequently the ialmrnt5 display error whenever I open .avi some stream .wmv video file and even full screen games.It only happen when I open a video files and high resolution game. I had try and reinstall the ffdcode and install dell driver from the provided dell cd an old driver but didn't help a bit. I did not try the new dell intel GMA driver because I scare it'll cause more problem. The weird thing where at dell driver website , they have 4 types of video adapter driver where my dell cd only have one driver 'Intel(R) 82845G/GL' http://support.dell.com/support/downloads/driverslist.aspx?c=us&cs=19&l=en&s=dhs Can someone kindly guide me which driver to install ? I hope someone can help me to read the minidump since I didn't know how to read it.I want to make sure whether it's cause by the the driver itself or my hardware component. If really cause by driver , which dell video driver I should install ? Thanks for reading my problem.
