Not long picked up a Rfm (3rd one
)
It's using original crt and computer but the computer has at some point been with Andy (pinballmania) and had a new power supply fitted.
Anyway when it arrived it was doing random resets (it was working great for previous owner and fully trust it was)
Anyway I decided today to take the computer out and check everything.. you can see it's totally clean inside its had a new cpu fan and new psu fitted)
Instantly noticed one side of the psu cable was not fully plugged down into the mobo.. it was shipped on pallet so guessing maybe that's caused it to jump out slightly .. anyway I thought great that'll be the problem but anyway I reseated all the parts Ram,prism ect and cleaned the connectors put it back.
It played for 20mins (bit longer than usual then reset.. so after that reset it was on playing for 3 hours straight fine until I had to shut it down and leave...
Any ideas what this could be?
One thing I didn't do was mess with the prism card I just left it complete and cleaned the pins before reseating.
Could it be old caps on the mobo? I didn't even check them tbh as everything looked really clean
It's confusing as it's staying on longer
Thank you
