I have a server that locks up randomly throughout the day, sometimes as little as 10 minutes apart. There is no particular rhyme or reason. All workstations/terminals get locked out, and the server itself is also locked up, with no error codes on the screen. You are forced to shut it off with the power button. I re-seated everything - no help. The CPU fan, and all fans are ok. Does anyone know any common problem with this model? Or a common cause for this kind of thing?

Defective RAM?

I could see if there are any known issues for ya, as I'm at work right now and am a gateway tech support guy.. one minute which revision of the 960. I have these listed.. 960 R4 (533MHz) 960 R3 (533MHz) 960 R2 (533MHz) 960

ISSUE NUMBER: 766600630 (1-641134607) TITLE: Disabling Hyperthreading on Single CPU 960/980 Running Red Hat 8.0 Causes Lockups ISSUE: Disabling hyperthreading on a 960/980 server running Red Hat 8.0 and the default SMP kernel causes the server to lock up during startup. If the server is dual-processor, or if the server is running the uniprocessor kernel, it works fine. PRODUCTS AFFECTED: Systems and Cases: 3501277, 3501327 Rack Mounts: 3501278, 3501328, 3501408, 3501410 Motherboards: 4000791 OPERATING SYSTEMS AFFECTED: Linux CAUSE: The cause is unknown at this time. RESOLUTION: Enable hyperthreading, install an additional processor, or use the uniprocessor kernel. hope this helps

Thanks for the responses!
