If you are one of the XP SP3 users that are plagued by the non-stop rebooting, you can breathe a sigh of relief today. A third-party, who is a formerly security manager for Microsoft, has released a tool that will be able to detect the problem and hopefully fix it.
The tool will prompt you to install the fix once you use it only if it detects a problem, and is a miniscule 16k VBScript file making it easy to acquire. The problem seems to be related to a driver intended for Intel devices which is attempting to load on AMD based machines. The tool is, of course, available for free. If you are suffering from this problem, it's definitely worth snagging it. It is unfortunate that once again a third party has had to step in, due to Microsoft being content with waiting weeks or even longer to fix these glaring issues.
