I recently reinstalled Windows XP with Service Pack 3 onto my computer, reinstalled Mach3 R3.043.022, and loaded my previous XML file. I run the Driver Test and get a steady 24,300Hz pulse frequency and System Excellent, but when I open up Mach3Mill, the diagnostics page reads a very low value for pulse frequency (1, 2, 3Hz, jumps to 24,300Hz for a second, and back down to 2, 3, 4Hz, etc.). I have attached my XML for you to look at and see if there is something that I am missing.
Before my computer crashed, I was running in ACPI PC with no problems but needed to replicate a problem that another machine was having (a steady pulse frequency of ~21,000). I went through the Windows XP Optimization Guide step-by-step to setup Standard PC drivers. After that, the pulse frequency was only 1 or 2Hz so I switched back to ACPI PC. That was when my computer crashed and needed the OS reinstalled. After all was said-and-done, I didn't replicate the problem but instead found a new problem. Will going through the Windows XP Optimization Guide again fix this problem?
