I'm having a problem with a random Fatal Error when Windows comes back from sleep mode. There doesn't seem to be any particular sequence to the event. It occurs whether the monitor has been on or off, whether the keyboard is used to bring the computer active or the mouse, or even turning the monitor on. Since the system was assembled on December 16, it has happened 6 times, today being the last time and the previous time was on January 4. The system components are: ASUS P4P800 Deluxe Motherboard Pentium 4 2.8 Ghz 800 FSB CPU Infineon PC3200 RAM 2x512MB To enable Hyper-threading Seagate 120GB Hard Drive Gainward Geforce FX5600 256MB Video Card Sony 19" LCD Monitor Software: Windows XP Pro (SP1 installed) Office XP Pro (No updates needed) Microsoft Project 2000 (no updates needed) Roxio Platinum 5.0 (updated) Any help would be greatly appreciated!!! Thanks!!
