Question about Computers & Internet

CPU overheating I was wondering if anyone knew about any cpu overheating problems with the gateway MT3422. I have read several articles on this issue, and wonder if this may be my problem. I noticed that the laptop does get really hot, even with a cooling unit underneath it. The computer is now not wanting to turn on after restarting due to recent updates. I get a power light on after pushing the button a few times, no other lights are on, the CPU fans does turn on and the cd rom does spin. F 12 or F2 will not bring anything up. Could this cpu problem be solved?

If you don't get anything on the monitor thats not a overheating problem, it could have been a overheating problem that has already damaged the machine.

Since your not getting any picture I would try the laptop with a external monitor, if you don't get any picture on the external monitor I'd check if your still on warranty or outside of warranty.

if your on warranty go ahead and contact your dealer or gateway for warranty service, which shouldn't cost much or not at all to you.

if your outside of warranty go ahead and try the instructions below:

unplug and take battery out. open up the memory cover in the bottom of the laptop, take both memory modules out from the laptop, now with no memory plug in the power adapter and try starting up, wait 1 minute and turn the laptop off, now place one of the memory modules back into the laptop and try starting up again, remember to unplug the power when your connecting or disconnecting parts from the laptop.

Does the laptop start up? If not, then take the ram module out from the laptop again, this time place it on the other memory slot and try again. If it still doesn't start up repeat the above with the other memory module if you have two.

if theres no improvement take the laptop apart, just disconnect all extra not required components of the laptop, modem, wireless, dvd, etc.

see if it boots up with just motherboard, cpu, cpuheatsink, other heatsinks, and one memory ram module, on power adapter.

if it doesn't start up, reseat the cpu you may also want to replace the thermal grease between the cpu and the heatsink, remember to wipe the old gease off, use DRY toilet paper or similiar, DO NOT USE WATER.

If the machine still doesn't work at all, it appears to be either the motherboard or the video adapter on the mainboard that has failed possibly due to overheating. You will most likely have to replace the whole mainboard. I would take the laptop to a local professional to confirm the fault.

or you could possibly buy a card like this

should come with a good manual of the code meanings, plug it in to the computer on the mini pci slot or the printer port and use USB for power, USB NOT NEEDED WHEN USING INTERNAL MINI PCI SLOT.

the codes that come up and the manual will point us to the direction of the problem. It does not guarantee that we can fix it. It helps in doing diagnosis at home and then replacing the part that is found faulty.

I'm pretty sure the issue is the mainboard or the video adapter. take it to a local professional to confirm the issue as I can't test your laptop over the internet.

Thanks,
Ekse

My gateway i-3 nv79 runing w7sp1 has a bad habit of shutting off with no warning ... downloaded coretemp and it seems like it is is overheating for no reason ... i can just be reading e-mail and it wi


Overheating When the CPU overheats then it will shut down (i.e. thermal overload) and won't boot up again until it has cooled down. If this is the problem is not fixed then the CPU will eventually fail.
A faulty fan causes the problem or the fan and heat sink assembly are clogged with dust.
Check the CPU fan to see if it spins freely, if not replace the fan.
If the fan and heat sink is clogged with dust the remove the dust and make sure the vents are clear and dust free. Use a small brush and can of compressed air to do this.

Hello,
It sounds like CPU is overheating, but other components such as the video card or motherboard chipset can also be overheating. It could be that the cooling fan either has failed or is starting to fail too. Make sure all the fans are spinning and the computer is several inches from wall and that the fan ports are unobstructed. This helps keep the CPU cool. Also try removing and reseating the processor; then reinstall the CPU heatsink with new thermal interface material.
I hope this help you.

The most probable cause is your Processor gets Overheated and causes restart to your system. Try having a suitable CPU Fan or go for a compatibility checking issue for your Motherboard and Processor.

Gateway M-6307 power dies on boot up (reaches widow screen dies)


Hi,

Make sure that it must be charged. If you are sure, there might be a problem of overheating.

If you check, there is a CPU fan. Overheating might cause thie.

Use a vacuum to cool on the fan to make it spin manually, hmmm it actually started to work after that.

If not, let me know.

Thanks for using "Fixya".

This solution worked for me. After Geek Squad had looked at it and said that there would be a new mother board needed. I can vouch for this solution. halo321@comcast.net

iam mohamad fakih from lebanon iv got the same problem but i solve it,the problem of this gateway is the high tempreture from the cpu this is what makes the damage
to fix it, easily just push the keyboard dawn hardly by your hand on the left side above the following keys:E,R,F,4,5 (u can use ur fist) push hardly and press power button and wait 4 seconds
and when the laptop comes on enter the windows and run aprogram that makes the cpu gets hot(a big game) this is to make the motherbaord become hot ,the heat of the cpu will automatically
solder the damaged bus in the motherboard . good luck

Random shut down


Yes.... over heating can and will cause a system shutdown..

Download and install speedfan ( http://www.almico.com/sfdownload.php ) It will most likely tell you how hot things are really getting......

Depending on what cpu you have, you may have a thermal paste problem, you may need to remove the heatsink and re-apply heatsink thermal paste to the bottom of the heatsink and reseat ontop of the cpu. This will void any warranty if you PC still has any left.

Gateway Laptop overheated and stopped working.


Usually when the laptop overheats the CPU shuts down, and after it cools down you may be able to power it up again, unless the CPU has failed.
If you are able to get the laptop working, get the fan replaced, if it laptop doesn't boot up then there is a serious problem (most likely a costly one).
