Regarding the power supply, it's very easy to test it.
1) Connect the "WP" to the ground to by pass "water protection"
2) Connect the "TL" to enable the power supply
3) Connect the HV (hot wire) to the anode of the laser tube (the coil side)
4) Connect the ground wire to the cathode of the laser tube (the output side)
5) Now be careful: Once you connect the "IN" to the "+5V" on the power supply, it should fire in full power!
(or, just press the 'Test' button)
Do those without connection to the DSP card. Just test the PS direct.
By the way, the 'error' during upgrade was 'bug' becasue of the USB chipset. You can hit Reset and do it again. Or, remove the USB cable when doing OS upgrade. Did realize this issue.
