It could be a NIC issue playing online or even a system driver issue but I bet its the video driver. Anyway something has caused an hardware interrupt which was badly handled. The interrupt could be caused from normal operation in which case the software driver is at fault but its also probable that an unexpected interrupt was generated because some hardware bit was too hot or otherwise not working to spec. Likely culprits here are the chip set since this does a lot of the interrupts in the core system - esp DMA which is used by both NICs and video cards.So... Is your chip set (Northbridge) temperature ok ? Does it have a heatsink on it ?If you think everything is cool enough and your CPU and RAM sticks are well seated, cables plugged in firm etc then look to the event log for inspiration.This is a really difficult one to pin down a solution for. It could be many things but you can narrow it a bit if you know what to do. Im afraid you need to put your hacker hat on...</blockquote>
