I'm experiencing software conflicts on my PC which is running on XP home, if I plug something in to the USB port after a short period of time my PC will lock up/freeze as if something else is trying to use the same files, does anyone know how to take a "snap shot" of my system when it freezes so I can identify what softwares are conflicting or is there when XP locks up or freezes does a log file get created?

* Pressing Alt-PrintScreen places an image of the frontmost window on the clipboard. Pressing PrintScreen by itself places an image of the entire desktop on the clipboard.
* Open MS-Paint. (From Start/Run, issue the command "mspaint".) Create a new empty image, and use Edit/Paste to bring in the screenshot you just took. (If the screenshot is smaller than the default Paint canvas, you'll end up with white areas. Start over: create a new empty image, change its dimensions to 1x1, and Paste again. The canvas will grow for the Paste, but it doesn't shrink.)
* Use MS-Paint to Save As, using PNG as the file format

How Do I Take a Screenshot?
