Hey Group; I recently upgraded to a new machine and have had nothing but headaches. It is a ASUS A7N8X-E motherboard with 512 megs. It is a Nvidia based chipset motherboard. I have updated all of the Nvidia driver/modules. Problems have been 1. Defective new memory - replaced - fixed 2 Printer not found - replaced the complete motherboard - fixed and now 3. Keyboard locks up now and then - it looks like the CPU. I found out yesterday while running the program "racer" which is a mouse drive 3D game with sound the keyboard locked up. The CRT, mouse and sound continued to function properly with the game. However, the keyboard failed. This keyboard has never failed on the older machine PS/2 type keyboard controller problem? I have seen in a pure KDE/Mozilla session both the mouse and keyboard lockup. Reboot and everything works again. "memcheck" shows no problem. Proper shutdown is not possible. On bootup, fsck seems to not always find a problem and everything works. Could it be a acpi, apm problem. I have tuned them off in BIOS and grub. Any suggestions to tracking this problem? -- 73 de Donn Washburn __ " http://www.hal-pc.org/~n5xwb " Ham Callsign N5XWB / / __ __ __ __ __ __ __ 307 Savoy St. / /__ / / / \/ / / /_/ / \ \/ / Sugar Land, TX 77478 /_____/ /_/ /_/\__/ /_____/ /_/\_\ LL# 1.281.242.3256 Dump Microsoft Software - Stop virus email Email: n5xwb@hal-pc.org " http://counter.li.org " #279316
