I have a Tri-Power Patriot. Ran fine for a year then motherboard fried over the summer. Switched out with a good computer and motherboard fried on startup. Tested voltages and thought I had a ground problem in outlet. Fixed that problem and installed 3rd tower. It ran fine for 3 months, but sure enough went to boot up today and motherboard fried. I feel like it has to do with the 25 pin cable. Unit was installed by Camtronics and not modified. My question is... The 25 pin connection on the machine side is just a circuit board that connects to the gecko drives, there is no circuitry on this board. So basically the Gecko drives are driven straight from the parallel port. Should there be a breakout board between the computer and the Gecko drives to isolate the signals? I feel replacing this "dummy" board with a breakout board, it would prevent unwanted signals getting to my PC. Has anyone had any similar problems or any suggestions? Sick of replacing PC's. Thank you.
