Perhaps an issue with Windows Directly...

the computer booted up perfectly yesterday, today, it gives that error, i have not installed any hardware or software in quite some time. and i am unsure as to the cause of this error.

I would prefer not to have to reformat, as i just built this computer last month, and freshly installed x64 windows xp. i have installed a number of applications when i rebuilt the machine, and i would prefer not to lose any of the applications or data.

I believe i have found the issue.

AMD Dual Core Optimizer was installed on my old hard drive, but not active, it somehow became active on my Windows XP X64 as a startup item.

I am using a Quad Core Phenom, this would explain why it was giving a critical stop when loading services...
