Help: get low system resources message at times after computer is idle

i will guess that it could be being caused by the "dell utility" (my own term for it), which generates errors when it cannot connect to the internet. you could use contol-alt-delete to pull up the task manager to see what is using all of the resources.. you can uninstall the "dell utility" in add/remove.

This method may show you after several hours which running application that is leaking resouces. By shutting down at start up apps that are not always needed you should be able to the problem child. What to do? Only start it yourself when needed and close it when through. Is it necessary to leave your computer on 5 hours for .......maybe it is needed, I do not know! Good Luck!

It is difficult to make any comments about causes with very little information.  I tend to doubt memory leak issue - reason I leave my PCs (Windosw XP Pro and Windows 2003 Advanced Server), on 24 x 7 for weeks at a time.  The  first step to resolve this problem is to gather information.  When you first boot the machine, start the task manager and note the following values, processes. CPU Usage, and commit charge, then minimize it.  Every so often copy the same information.  When you get low resources, copy the same information and try to save the process list to a file.  (use cut-and-paste to save the data to a file).  Post you results.

Here's a few quick questions for you - how full is your hard drive?  What screensaver are you using?

I've seen isues in the past where these type of errors start to pop up due to a screen saver and a nearly full hard drive.  Usually the screen saver is a picture viewer that loads all the images it cycles through into memory, and they eventually get transferred to the swap file.  If you don't have a static swap file, the swap file will continue to grow as it needs more space, and possibly use all remaining hard drive space.  When you run out of hard drive space, Windows will return an error about insufficient system resources, due to the swap file running out of room to grow.

A few simple solutions then are 1) Clean some of the junk off your hard drive, 2) Change screen savers, and 3) create a static (fixed) swap file.  Any of these will help if the issue is tied to the screensaver...
