Chip - I've just taken a looooooook at the log file for today - er, now what???

Errr... good question, Ed!

Major edit - use System Monitor instead of Counter logs, so you can watch the memory usage in real time - as per instructions in the MS article.

In Performance, select System Monitor, then the click left hand button above the graph (New Counter Set). Click the + Add button.

In Performance object dropdown, select Memory and select Pool Nonpaged Bytes from the list and click Add.

Next select the Objects performance object and add Threads from the list.

Next select the Process performance object and with the All Instances option selected, add Pool Nonpaged Bytes and Pool Paged Bytes from the list.

Click Close and the real time graph will start. Watch for a climbing stair effect. You can double click on a coloured line in the graph and it highlights the corresponding item in the lower part. You can also remove an monitored item by selecting it in the lower part and pressing Delete - useful if you've decided that a certain process is not the culprit. Click View Graph, Histogram and Report buttons to see the real time data in different formats. Click the Red X to freeze the display and then the Camera to get the current snapshot.

OK - I'm running that now. I'll let you know what it throws up...!

I ran System Monitor until the pc died. The graphs were nearly as flat as a pancake - no sign of a staircase...

Hmmm... sort of half expected that after you said processes were using normal amounts of NP Pool.

Have you tried using Poolmon.exe outlined in the first MS article? Never used this, so I'm not sure if it'll just give the same result as Perf mon.

In Control Panel - Admin Tools - Comp Mgmt - Device Manager, are there any devices with red or yellow icons? Try Update Driver for each device, or even Disable - but that's the old needle in a haystick problem - which one(s) to disable.

Try starting in Safe Mode - both the normal safe mode option and safe mode with networking. Does the problem still occur?

In Msconfig, select Diagnostic Startup and reboot. Does the problem still occur?
