Gateway DX4300 that repeatedly shuts off.

October 13, 2010 at 10:21:03
Specs: Windows 7

I have a Gateway DX4300-11 that repeatedly turns itself off. I purchased the desktop in mid-January/2010 and this problem began to occur in mid September/2010. The computer will sometimes run for a couple days with no problem and sometimes it's less than an hour. I have spoken to Gateway support and have been asked me to restore the system back to factory settings as they want to rule out the possibility that Windows 7 (64 Bit) or other software conflicts are not turning the computer off.

I am not convinced that the OS or software is creating the problem as the system is so locked up that I have to unplug the computer and repower in order to have the system respond. When the system turn off depressing and holding the power button will not have the computer turn on eventhough the power button light remains on. I have read other posting on line and some DX4300 users are of the opinion that the problem is a power supply issues and/or an overheating problems.

Overheating does appears to be the problem. How the overheating effects the motherboard I am not sure, but I performed the following test to determine that overheating is causing the system to turn off. I have taken a small fan and aimed it at the computer and the computer will run for days on end with no shut downs. The first was a 5 day period and then I followed it with an eight day run. To confirm the heating issue, I then operated the computer without the fan in operation and the computer would shut down within a couple of hours. I repeated this half a dozen times and the computer would always shut down. Once again, I return to using the fan aimed at the computer and the computer does not shut down. It has been running now for a couple of days with no shut down. Again, I am convinced that the computer is shutting down as a result of an overheating problem.

Back to Gateway support I will return. I will keep you informed of how they respond to this defect in their product.

Download a free program called speedfan, and monitor your temps if you haven't already done that.

I just started having the exact same problem -- even the date of purchase of start of the problems are similar. Please let me know what you find out.

I too have just started to have a similar problem. The lights are on but no output is being sent to the monitor. If I unplug it for a longer period of time the splash and everything ekes boots back up. Has gateway support told you anything?

I installed SpeedFan and definitely seemed to be running hot. Also tried putting a small table fan blowing directly on it. Seemed good for a while but then shut down twice yesterday. We're in the middle of a heat wave out here in O.C. (100 yesterday) and I don't have a/c going so it's probably 80 or so in my place. Today I went to MicroCenter and got an Antec HGC 520 pwer supply -- it was a returned item on sale for $70. It's a higher end gaming power supply unit (I don't use my system for gaming though and I have the stock video card).

Install was pretty straight forward. The fan on it is on the bottom so it seems like you're installed the unit upside down, but it fit in just fine. All of the cables from it are shielded and it has many more than the stock unit. Tip for installing: I unscrewed the stock unit and pulled it out onto the desktop -- the cables are long enough to reach without unplugging any of them. Then with the new unit next to it, I pulled each power cord and plugged in the matching one from the new unit. When I had them all connected, then I put the new unit inside the box.

In SpeedFan I have all three fans (CPU fan, rear case fan and the new PSU fan) set to "Software" under the advanced config settings. So far it's running silently and the temps seem to be staying in the green zone.

While I had the case open I also thoroughly cleaned the CPU fan and found significant dust inside it -- I've used compressed air to clean the unit regularly but when I went at it with cotton swabs I pulled a fair bit out.

Now it's a matter of seeing what happens over the next few days. I'll post back my results in case this helps anyone else with the same issue.

24 hours in and no crashes! It's running nearly silently and all the temp readings are staying in the comfort zone. Hopefully this is all it needed, I'll post another follow up in a week or so when I've got longer term results to report on.

I have the same problem with my Gateway 4300, but for the first time after being off (and unplugged) for 8 hours it will not turn on. Power source is good, as fans and CD drive both work. Inside of case is full of dust - i removed much of it with a Q-tip, but still a lot remains. Any advice? Am I on the road to get a new motherboard?

I've been having the same problem for months on end - the PC only stays up and running if the case is opened and a fan pointed at it. I've added additional fan cards to the slots and added another large case fan, and that improved the uptime to about 2 hours from 5 or 10 minutes, but nothing permanent yet. Gateway is, of course, completely worthless here. Did anyone ever find out if the bottom line issue is the motherboard or the power supply? I really don't want to dump 100's into a 600 PC to make it work as advertised. Thanks!

Gateway replaced the power supply and my computer has been running without shut-downs for a few months now.

@Geob, was your computer under warranty? My warranty just expired and now my dx4300 is doing the same thing. How did you get them to replace the power supply? It seems absurd they would put only a 300w power supply on this machine. I am getting the same shutdown issues and I think it's the same problem. It shuts down pretty quickly if I turn on my 46' plasma and run hdmi out to it, so at first I thought maybe the video card was getting too hot? Either way, this is weak.

It has been many months since Gateway replaced my power supply and my desktop has been running without any shut-downs. No more fan blowing into an open case! I am not sure the power supply was defective or under sized. If you are no longer under warranty I would suggest replacing the power supply. Look at the one in your case and determine the wattage and then go for a larger replacement. Good luck!

Jim, you have described your problem identically to the problem I was having. Gateway replaced my power supply and I no longer have the shut-down issue. I believe the power supply was defective or undersized. I am sure Gateway is receiving many calls from 4300 end users. If you are still under warranty have them replace the power supply. Good luck!

Just replaced the 300w power supply in my dx4300 with a 500 watt power supply and after several days no problems at all.

My problem is is that it shuts down. doesn't restart at all, just shuts down. I think that may be the issue as well. We are also going through some bad temperatures here, (90-something degrees and climbing.) where I live. :/
