System Lockups

By larry.kahn ·
I have several Work Stations, PentIII-600, 384 Megs of memory, 64 Meg Video Card, (hi-graphics cadd use), 9 Gig SCSI machines, that for no particular reason will lock up. No keyboard, no mouse, no event viewer, no messages left in the event log, just nothing. I try to maintain a good relationship with DiskKeeper 6.0 and manage to keep the TMP files down to a min. Pulling what little hair that I have out. Any suggestion would be helpful.

System Lockups

by cbabbage In reply to System Lockups

Root Analysis: System lock ups are generally the result of poorly behaving active processes (foreground or background) or bad hardware component/bad hardware configuration. Poorly behaving processes are typified by memory trashing via out of bounds references and inability to 'play' with other hosted resources on your system. Unless you have a plug and play/pray (NT4.0 is not plug and play) you will need to be sure that you do not have IRQ resource conflict between your Video Adapter, Network Adapter and your SCSI host bus adapter and any other 3rd party devices connected to the workstation

Resolution: SCSI devices require that you check for proper termination and equipment configuration. Your mention of DiskKeeper suggests you are running Windows NT 4.0 as that is the OS without the functionality provided by DiskKeeper. Check to be sure that it's OK to run DiskKeeper aginst a SCSI harddisk and does not conflict with resources used by the SCSI host bus adapter (check above).

Hope it helps.

Make sure that the power supplies have enough oompf. With your hardware, I would use at least a 300Watt supply.

Next, check your cooling.
Make sure that the fans are running fine, and that the vents and heatsinks are not covered in dust.

I assume that you have checked for updates for the cadd software, and are running the recommended NT/2K service pack for the cadd software.
