I have two different PCI parallel port don't remember brand but they are different. (all drivers have been download from the manufacturer website)
I have remove different driver, one by one to see if it's make any difference but just a bit.
Tried PS2 mouse and USB mouse. PS2 mouse still running even if I turn on spindle, but lost the USB mouse when doing the same thing.
Does not makes a big difference when Mach3 is running or not like pictures posted in a previous post.
Did get another board today, ECS K7S5A pro Rev 5.0, 1Gig or ram and 2600 processor, have downloaded drivers from ECS website and will try to install Windows XP tonight(for me)
That's what I did for all previous motherboard.
But this time, will not install any driver for the moment and test Mach that way, if it work, will not make any change.
Could try to buy a new mouse to get a driver, maybe from logitech, they're no driver for a standard optical mouse, just the windows driver.
I have tried a bunch of graphics card but no change (some ATI )
Still trying but thanks for the help.
