Megatouch XL upright bootloops every half second; tried new PSU, mobo, and RAM

Wow, that really is weird. Especially since I have two motherboards to test!

obcd:
In fact, it's so weird that I decided to try it out myself.

Initially, it wasn't giving me a picture either, so I installed the io card.

Bingo... Got a boot screen..

Now, the funny part.. I removed the io card again and... It still boots without it. (Expected behavour)

Isn't technology wonderfull?

No idea why it wouldn't boot the first time.
It has been in storage for several years with the battery removed...

DaddyLongLegs:
Well I determined on the 2nd motherboard that the riser card definitely isn't helping. It's a BRAND NEW riser board which is crazy. I had an older one that I cleaned like crazy and I still have the same results.

Luckily I can plug the io board directly in because I have an upright and everything will still fit. But people with bartops would be screwed as they would have to use the riser board.

I guess I can just leave it directly plugged in but I am wondering if that is what ruined my other motherboard (me moving the cabinet across the room with it plugged in directly. Maybe the io board wobbling permanently ruined the slot on the motherboard?)

I would directly solder the damn io board to the motherboard if it wasn't going to be a million wires!

mahkeymike:
did you try cleaning the contacts with a eraser and also use some 220 grit sandpapper to slide into the ISA slot on the mobo? you might want to wrap the sandpaper around something like a credit card so it gently makes contact with the pins in the slot. Be careful not to side to side. Only straight up and down motion.

does that riser board have some capacitors on them? in particular tantalum capacitors where pretty popular around that time.. they often fail shorted...even for no reason.
