My laptop is a Dell Latitude D630 with 2GB RAM and WinXP Pro. When I run several large programs (or Firefox with several tabs, Flash, etc.), things just get very flaky until I reboot. Text disappearing in some windows, weird title bar colors, programs failing. My page file is at 4GB. Is this normal, or is there something I can do to fix it?

It's probably not memory you're running out of, but available handles or desktop heap. Dan over at Dan's Data has a page about other resource limits in Windows XP. I experienced similar issues until I upped the limits on this machine, which has 4GB of physical memory. My handle limit is currently set to 18,000, my system heap to 8M, and my desktop heap to 512k. I haven't had any troubles since increasing these values.

With XP and 2Gb of RAM this is not normal. I don't know what large programs are you running, but Firefox with even more than 20 opened tabs should work without freezing your laptop.

First thing you should try is some handy utilities to detect and remove spyware and other 'garbage' things, similar to AdAware.

Yes it is normal for Windows, especially when it has been running for several days. But, no it is not normal for a superuser to reboot when this happens. You should start closing things when you notice the machine getting sluggish, or the fan getting consistently noisier, or the drive rattling noisily on and on.

I general start by closing any extra Internet Explorer windows. Then I open up task manager, sort by CPU and see if something is popping to the top of the list too much. If so, I close it. If Firefox is running I kill the process in Task Manager because it saves the tabs and restores them upon restart. Also in task manager, look for processes with really big memory. They are probably causing too much disk activity by swapping in and out. With Google Chrome, I generally close tabs with known problem sites like Google Mail and Yahoo Mail. Sometimes I need to kill iexplore processes in task manager even though all the browser windows have been closed.

If I do this, I can usually find the culprit and still have half a dozen apps running with a dozen Windows open. If I closed up spreadsheets or word documents that I need, I can always reopen them quickly with the File menu choices 1, 2, 3, 4 etc. You can expand that up to 9 in the options, I believe.

All in all, I can usually sort out the problem without a reboot, and without losing much of my working context.

If it is Firefox (and Flash) that are hogging resources, I'd recommend the AFOM addon to reduce memory leakage. This won't fix the issue, but might help a little.
