Random Shutdowns, overheating. Gateway laptop

Specs: Window Vista, AMD Turion 64 X2
Gateway MT6459

From reading on the internet this PC is known to have high fan use and gets hot but is their a fix? I was given this laptop dead, I would push the power button and lights came on for a split second then went off. POST never happens and the fan was off. I opened the laptop up and removed the RAM and HDD, discconected the LCD screen, nothing. I then removed the fan and CPU and the PC would boot. Reseated the CPU and it continued to boot. I hooked everything back up and cleaned out the dust and the computer booted like normal.

I noticed the fan was constant even though I wasnt doing anything. I let it sit and it shutdown within 5-10 minutes at around 90C. I did this with semi poor airflow on purpose to see what happened. I then did the same but with better airflow and it didnt shutdown but the fan was constant and the laptop was very hot. (Again I wasnt doing anything on the laptop)

I ran Hirens Boot on the laptop and tested the memory, HDD, and video card and all came back fine. When running the S and M stress test with good airflow, the laptop eventually shut down. Malware/Virus tests came back fine. No other processes are randomly spiking. I upgraded to SP2 and all drivers, software but still have the same issue. Should I upgrade Vista? Buy a cooler?

Thanks for the help

Clean out the air vents from dust using compressed air from a distance, don't use a vacuum cleaner and reapply thermal paste.


If you took out the CPU, how can it boot when theres nothing to process the instructions, it would most likely beep or a light would flash.

I am a hardware guy not a software guy but i try to help.

Thanks Jay. I didn't mean that it "booted" just that the power light remained on and the other lights started coming on like normal. Before all I was getting was a blue power light for 1-2 seconds then back to off.

I did clean the vents while I had the laptop apart. I was hoping I could find some kind of software or even hardware to make this laptop last longer for my friend. It doesn't seem normal that this fan should constantly run but maybe thats just the poor engineering of Gateway on this laptop.

When you put the CPU back on did you take off the old gunk/paste on the CPU and GPU and put some new gunk/paste on?

My laptop's fan runs constantly so it cools it, if your laptops fan is running fast then the CPU or GPU is getting hot, 90c is too much for a laptop.

You MUST use paste & it MUST be applied correctly. The cheap "heat sink grease" available at Radio Shack is as good as any.


Find your CPU & follow the application instructions exactly:
