Troubleshooting
Please note that many of the symptoms here could simply just be bad capacitors. So if none of the fixes below work for your issue, replacing any through-hole capacitors is a good last resort before replacing your motherboard, especially ones that are bulged, leaking or have visible damage
The N2 will not turn on whatsoever
Check the PSU cables are plugged in correctly, if the N2 still does not turn on try a different psu, if it still shows no life a new/repaired motherboard is likely required)
The N2 turns on but doesnt output any video/initalise
Check RAM, if the faulty RAM is in DIMM 2 slot the N2 does not always output a bad RAM beep code
The N2 turns on but shuts off after a certain amount of time with no signal output
Make sure the CPU is seated properly and is being sufficently cooled/powered. Trying a new PSU could also help. If neither of these work the CPU may have burned out or the motherboard may require replacement/repair
The N2 outputs a high low siren tone from the internal speaker
Make sure the CPU is seated properly and is being sufficently cooled/powered. Trying a new PSU could also help. If neither of these work the CPU may have burned out or the motherboard may require replacement/repair
The N2 outputs a tone out of the internal speaker other than the one above
Check that your RAM is seated properly, If this doesnt work try a different ram slot and/or taking out one ram stick and leaving the other in (if you have 2GB). If these dont work either your motherboard or GPU is most likely faulty
The N2s screen output is filled with "Boot failed..."
The baked in bios linux os cannot find aeinitrd/aevmlinuz, or said files are invalid. Check the HDD is plugged in properly. If this does not work either the HDD is no recieving enough power, the IDE controller on the motherboard is dead, the HDD data cable is faulty or the HDD itself has died
The N2 displays "Failed to load prod.img" during bootup
The hard drive has been found however the system has failed to decrypt the final stage linux kernel. Make sure that a GPU with the custom bios is inserted, JVS IO card is not faulty, and that hard drive is connected/working and the original namco one and NOT a cloned drive. This could also be caused by data corruption
The N2 freezes during the bootup process
Try a new HDD. If this does not work then a device in your N2 may be faulty. If the N2 freezes on a module load the module could give away the fault (nvsound is sound, nvidia is video, forcedeth is ethernet)
The N2 has weird artifacts on screen/corrupted 3d graphics
Try a replacement GPU. If this does not work try swapping the RAM. If neither of these work your HDD or motherboard is faulty
The N2 randomly shuts off/freezes
Try a new PSU. If this does not work try repasting your CPU/GPU as they could be overheating. If this still doesnt work your motherboard is likely faulty
The N2 is running slowly
Firstly try a CMOS clear (remove the battery, wait a minute then re-insert it), also make sure the CMOS battery has sufficent voltage. After performing this, wait for the "Please reboot to clear the system message", leave the game running in attract mode for 10-20 minutes and do a final reboot. Most of the time this resolves it, as default CMOS settings sets the FSB/CPU multiplier incorrectly. If not, make sure that your CPU is at least 2ghz and your GPU matches or is better than the original spec. If neither of these work try repasting as your CPU/GPU could be overheating. Upgrading the RAM amount from 1GB to 2GB is also known to help with maximum tune 3dx+
Psst, if you are running a wangan cabinet, see Wangan Midnight Maximum Tune 3 Documentation, which provides some game specific troubleshooting
The N2 occasionally generates graphical issues even with a new GPU
You most likely have a few bad capacitors on your motherboard that need replacing, look for bulged/leaky capacitors and replace them
The N2s audio output outputs a high pitched whining when nvsound is loaded
This is caused by a bad audio circuit. Try replacing the surface mount caps around the audio IC at the bottom left of the motherboard, otherwise replace the motherboard
An update usb is inserted but the game boots as normal
The update usb is not detected or formatted incorrectly, please ensure the update usb is not faulty
