Inspiron 1525 Crashes after 1-4 hours
- I have a Dell Inspiron 1525 that unexpectedly shuts down after an hour or more
- The machine worked fine for about a year and now for the last couple of months I have had the unexpected shut down problem
- I have re-imaged the machine multiple times (after repartitioning to eliminate boot sector viruses) , each time loading the latest drivers in the recommended sequence to no avail. I initially used my own Vista Ultimate but have now gone back to the OEM's Vista Home Basic OS. After the last re-image I only loaded the most important few drivers from the Dell Support, an AV program (AVG), Firefox and updated the OS - still crashing.
- No new hardware installed. Have not done a BIOS update.
- Fan seems to be working harder than it should be. It revs up often just before crashing. Ran Speed Fan and it shows 78-83F or below in both cores, though.

Hi,
Sounds like your 1525 is getting too hot. If you take the back plate off where the memory goes, you'll see in the top right corner - the heatsink for the cpu. I would highly recommend cleaning this out as the heatsink gets clogged up with dust and fluff (I've seen it many times when someones bought a laptop round and its turns out its dust thats clogged up in the heatsink which is making the cpu hot and the laptop shuts down for safety), if the laptop is out of warranty then you could also try cleaning the cpu and heat sink as applying some arctic silver 5 on the cpu would help as well. But only do this if your confident with this (ie: system builder / repairer) and remember to clean the cpu and heat sink of the old thermal grease before applying the new grease.
If this doesnt fix the problem I'm not sure without looking at it.

Hi Royds,
The thermal idea is a good one. When I ran Speed Fan though it showed 78-83F or below in both cores - this seemed OK to me. Still think I should clean out the CPU heat sink?

You could give it a clean it wouldn't hurt. But I would do this at the same time as renewing the thermal paste.
