I am running Windows XP Pro x64 with an AMD 3400 CPU. I’ve been using the 3400 processor for almost a year and Windows XP Pro x64 runs fine. I recently decided to upgrade the processor and installed an AMD 4000 CPU. With the 4000 CPU, the system goes through the bios startup with no problem and the CPU is recognize, but it does not go into Windowx XP Pro x64. When I go into Safe Mode it goes through the Windows startup files and stops at a file with the named acpitabl.dat and hangs. Nothing else has been changed in the system other then the CPU.
Can anyone give me some advice on this problem? Thanks.
