Laptop keeps locking up

post #1 of 9
Thread Starter 
One of my many laptops (evesham) keeps locking up. The CPU was previously very hot, (90c), But I put Arctic Silver 5 paste on it and the temps stabilised to about 45c. I used speedfan to monitor them and found that one of the temps was about 70c. I can't hear the fan, but speedfan registers it working intermittently at about 2500rpm when it does. The CPU is a 1.86 Ghz centrino duo, and it has a 256MB Radeon X1800 PRO dedicated GPU.
Anyway, should I just replace the fan, or do you people have any ideas?

Those temperatures are EXTREMELY hot. 90C is very close to boiling temperature for water. I would not be surprised if your CPU is permanently damaged, in addition to the hardware surrounding it.

did you pull the thermal pad off the heatsink before you put artic silver on, if not you will have to. You might also need to use a really thin piece of copper(AS5 applied on both sides) to make up the space of the thermal pad

In my experience laptop hard drives are well known, after a period of time to develop bad sectors. Loose ram is another easy fix and common issue so I guess in short my suggestion is to run some diagnostics on it as well and do some basic troubleshooting to rule out other hardware that might be causing trouble..... If you haven't already of course. If you can, remove the keypad and verify that the fan is not moving.

Well, just to update you, I ran diags on it and they all passed. I tried setting the fan manually to 100% using speedfan, but it still wouldn't work. Annoyingly, the fan comes on for about 3 seconds on boot, so it clearly works. Any more ideas?

Check the BIOS and see if there is a setting for constant fan... Might be one of those laptops that the fan only comes on at a certain temperature and yours is messed from the overheat.

Have checked BIOS, and there's no options for anything like that, all options for CPU are greyed out.
