Sorry to be the bearer of bad news but Gateway machines are fitted with Bestec power supply's (dreadful things) and usually when the power supply goes it takes the mother board with it.
I live in an area prone to electrical storms and I probably get one Gateway machine a week into my workshop with exactly this problem.

Power switch stutters when depressed. PC will not turn on. Has been happening for more then 4 months. To avoid would leave computer always turned on. Unfortunately a reboot stalled and I had to power off...


Try connecting the reset switch in the place of the power switch. Both of them are push buttons so your only problem is that you have to use ctrl+alt+del for reset.

I have a Gateway 831gm It was working fine until I unplugged it to move into the other room. now it won't start. I can get the fans to start if I hold the button in but the lighted switch and power light...


You power supply is broken. It can happen at the drop of a hat. Plug in your PC model in google and follow it by the words power supply. You should be able to get one for $20 or less.

Gateway 831GM Eratic Fan Noise


Hi,

This can be caused by several things:

1. Bad temp sensor
2. Bad voltage, but that will usually cause the whole system to restart
3. Too low maximum temp setting inside the chassis(setting is in bios), often denote as max case temp.

One way to bypass the problem is rig the fan to a molex adapter with a variable voltage molex to 2/3/4pin fan connector and adjust the speed to the maximum quiet setting.

The 831's did run a bit warm so if the case temp setting is set to low it will fluxuate quite a bit. Try adjusting the max case temp up around 50c just to see if that does it, if it does either use the variable voltage dial solution or add a second case fan that's always on, prefferably a low RPM running direct off molex so it will reduce the average temp and therby the need of the monitored case fan to rev up.

Gateway 831gm not booting. Fans come on but no boot process.


2 questions:
When you say new motherboard do you mean an actual new motherboard or new to that machine, but came from another used model?
When you say you tested the power supply do you mean with a voltmeter/ammeter or put it in another computer and it worked?
I worked on several gateways with similar problems and it boiled down to motherboard issues.
I tested it by replacing the power supply with a bigger (used) power supply and it worked great (for 1 time) and then put the other power supply back in to confirm my diagnosis and yep it wouldn't boot. The next morning I was going to run some virus/malware cleanup and installed the other (known good) power supply and it would not work. I tried all day to get it to boot and it did about twice in a 4 hour period. When it did run it would run great but any attempt to restart it would cause it to crash. No ryhme or reason, it would not fail the same way more than twice. Sometimes beeps, other times no beeps, sometimes it would start up with no video (could hear the Windows starting sounds) other times it would start up normal. I could let it sit and it would start or I could keep trying in sucession and it would eventually start. Some times the fans would slow down from a roar, sometimes they wouldn't. So with a known good power supply that had 150 more watts than the original I diagnosed it as a failed motherboard. But if you have put in a brand new motherboard then I would replace the power supply, because a bad power supply does not mean no power, just not enough power. Please post back and let us know what you find out.

Gateway 831GM Video card


The 831 only supports 2 gigs of ram any more and it wont start. You can probably fit a 9800 in it but would be a very tight fit.
