How to run diagnostic on DE-10

[lamp]

Hello,

Having some issues with stability.

Occasionally the keyboard locks up, and I had an issue where after loading a core (with no system rom), loading other cores had seriously garbled video. Even the snow effect on the main menu was messed up after a soft reboot. Doing a hard reboot resolved the video corruption.

Wondering if I can do a diagnostic to work out if there is anything wrong with the unit.

I wonder if it might be the power supply. I added an IO board and a USB hub board, and wondering if there is enough power. I was plugging in a USB Wifi dongle, a keyboard dongle, a wired Buffalo pad. The fan of top was set to low speed, and I wasn't doing anything strenious during the crashes (running 8-bit computers at stock Mhz).

I see that the official PSU is rated at 2Amps but there are PSUs that go up to 4A.

Just want to be sure that my board isn't broken.

Thoughts?

The garbled video thing (that clears on hard reset) is 'normal'.

I believe it happens when cores switch too quickly. Not sure what else affects it, but a power cycle always fixes it.
