Taito Type X3 restart-looping. Any ideas?

[buffi]

Bought a very cheap untested Type X3, but turns out it was cheap for a reason

At startup, it shows the bios image, then shuts off and restarts again endlessly.
Anyone have ideas of common failure modes for these, so what to check first?

I actually have a working Tx3 in storage, that I should be able to grab and swap parts between them until I find out what's busted... but then I need to go get it from an external storage location first, and maybe there's some common problems with these I'm not aware of.

It's a Nesica2 drive in it fwiw.

Crashes after this:

Try the ram first

RAM and Storage would be my guess, too. That crash, to me, either says it's failing on the attached drive WDC WD10JPVX, or it's failing on the next step whatever that is. But gotta run through RAM at some point so that's a good start.

Tried removing all but 1 (trying different ones), and same issue.

Could definitely be storage though, should see if I have some other drive somewhere to swap it with until I can get my other Tx3 here

Ok so. Brought the other one over. Opened them up and yeah… theres the problem

Someone managed to smash the security thing plugged into pcie enough to fuck the connector. Will order a replacement and try soldering a new one i guess.

Trying to build a working strong and fast unit based on these two now, and will jam the shitty parts into the broken one for now

gonna take forever to lick this clean

 

[buffi]

Wtf?

 

[buffi]

Well, moved the better cpu, gfx and ram to the working mobo and hey.

Now bleh. This will suck.

I’ll just leave the shittier system as spare parts. At least have a good working one now.
