A variety of complaints about SP3 are being posted on the Web, with users complaining about system crashes, spontaneous reboots, and other issues. On the Windows XP forum at Microsoft.com, for instance, a poster named Doug W. said that, after installing SP3, he had to use system restore "after three attempts, with different configurations each time." He mentioned that his system has an Athlon chip from Advanced Micro Devices, and other users have reported similar problems with SP3 on AMD machines.

AMD-Based HP Machines

According to news reports, a Microsoft document lays the blame for the endless reboot problem after installing SP3 on some computer makers. The issue, the document said, is when the XP disc image is created on an Intel-based computer and then run on a non-Intel-based machine, such as an AMD one.

Jesper Johansson, who used to work for Microsoft, noted on his blog that Microsoft identified the same problem with Service Pack 2 for XP, and that the particular problem is unique to Hewlett-Packard AMD-based desktop machines.

He quoted the company as saying in an article written following the XP SP2 problem that it did not support using a computer with one kind of processor to run an operating system based on an image created on a computer with another kind of processor. The article described how to modify the Windows registry to correct the problem.
