The processor isn't a problem, it's 256meg of RAM with Microsoft's 3rd generation enhanced DOS shell 32-bit GUI emulator called Windows ME that's the problem. Windows 2000 plus a RAM upgrade will fix this.
Assuming it worked before means you've had to re-install some Windows OS, likely ME - See advice above.
You can probably fix this by manually forcing the Windows swap file to a manual gig minimum/maximum, reboot, and then set Photoshop's memory utilization to 80-90%.
Then, disable CleanRam becuase all these utilities do is compete with system resources.
