I hope ths is a small and quick fix but I'm just not sure. I picked up an N64 about a week ago from the goodwill. It played well the 1st day but since has come up with a kinda "glitch". The console will reset itself after about 15-30 minutes of gameplay. Every time it does that the next reset will come sooner and sooner. I have heard the issue could be that its dirty (which is a strong possibility) or to remove the expansion pack or  that the ac plug is no good anymore. Should I open the console and clean it well or just go ahead and purchase a new ac power box? Or is the console damaged? Any and all help would be greatly appreciated, thank you in advance. 
Replace the power supply. Occasionally the OEM power supply can go bad. The console resetting itself is a sign of a dying PSU because the CPU is not getting proper voltage on the 3.3V output. The N64 console should still be fine once you give it a new PSU brick.

One of my old N64s started doing this. I checked the controller port with a multimeter while running Banjo Kazooie as a stress test. The voltage is supposed to be 3.3v but it started at 3.11v at boot and slowly dropped from there the longer the console stayed running. Around the time it dropped to 2.92v, the console spontaneously reset itself and would continue to do so until I powered it off.

I bought a used OEM power supply from GameXChange and that fixed the console. 3.34v steady with the secondhand oem supply. I haven't tried the new replacement supplies but they offer 3rd party new replacements as well. As long as they output stable 12v and 3.3v signals, they should be good.

Always best to test 3rd party supplies with a meter first to make sure it's not putting out too much juice. I've seen "9v" Yobo NES/SNES bricks putting out a whopping 15v out of the box. Yikes!

EDIT: Holy shit this thread is old. Still though, check the voltage at the controller port (1st and third pin) while running if you have access to a multimeter. If it's well below 3.3v, it's probably a bad supply. Never heard of fixing the console with paper shims or tape and stuff. The solutions you guys come up with is grand. Excellent information Kosmic! I think my psu has this issue. Didn't even think of checking the voltages through the controller ports under load. You think replacing the caps is all that's needed on these psu's that no longer have enough juice? ]]> N64 "Resetting http://nintendoage.com/forum/messageview.cfm?catid=8&threadid=33302 2018-06-24T04:25:48 -05.00 dodgerdanny 30 Originally posted by: dodgerdanny

With that being said...if a game resets with a clean reset button, that tells me the pins on the board has corrosion. Which can be cleaned with a wire brush. ]]> N64 "Resetting" Problem http://nintendoage.com/forum/messageview.cfm?catid=8&threadid=33302 2018-06-23T22:12:26 -05.00 dodgerdanny 30 N64 "Resetting" Problem http://nintendoage.com/forum/messageview.cfm?catid=8&threadid=33302 2014-01-10T13:23:47 -05.00 dodgerdanny 30 N64 "Resetting" Problem http://nintendoage.com/forum/messageview.cfm?catid=8&threadid=33302 2013-12-31T01:30:36 -05.00 dodgerdanny 30 N64 "Resetting" Problem http://nintendoage.com/forum/messageview.cfm?catid=8&threadid=33302 2013-12-30T20:04:17 -05.00 dodgerdanny 30 N64 "Resetting http://nintendoage.com/forum/messageview.cfm?catid=8&threadid=33302 2013-12-20T00:39:46 -05.00 dodgerdanny 30
