My Dell Inspiron 1525 shuts down randomly, it's running Windows 7.

I checked the error log and this is what the last error was:

Event 37 Kernel-Processor-Power
The speed of processor 1 in group 0 is being limited by system firmware. The processor has been in this reduced performance state for 60 seconds since the last report.

There have been a number of 'event 37' logged at different times just today in the error log.

Any idea how to solve this error i have installed all the drivers and the firmware and this error has just occurred lately I have been using Windows 7 for atleast 2 months now ( I reloaded my entire installation just today and it shut down again without any warning so now this is getting me worried)

This is a stab in the dark, really, but is it possible that your laptop is overheating? The reported event could be an attempt to keep the processor from overheating.

Can you give some more detail as to what happens when it shuts down? Does it shut down normally or does it immediately power off?

It just immediately powers off no warnings whatsoever, i'm working on something and suddenly poof my laptop's off – rzlines Dec 21 '09 at 5:08

Well, immediately shutting off is consistent with overheating. Have you tried booting it directly after it shuts off? I've had random overheating occur with an Inspiron 1420 while performing similar tasks to yours, and if I attempted to boot without waiting for twenty to thirty seconds after it shut off, I would get a BIOS message telling me that it was refusing to boot due to overheating. – Emory Bell Dec 21 '09 at 5:17

Hmm. Does your Inspiron have an integrated GPU or an independent one? I eventually junked my 1420 (with an independent GPU) as these problems became more frequent, but in it's last few days, I noticed random artifacts appearing soon before the overheating occurred, which led me to believe that my GPU was overheating. However, it doesn't look like SpeedFan found a GPU... At this point I would suggest leaving SpeedFan running and keeping an eye on it to see if there are any spikes in temperature before the next occurrence of the problem. – Emory Bell Dec 21 '09 at 5:33

Additionally, according to processorfinder.intel.com/details.aspx?sSpec=SLGJ4 your processor is well within operating temperatures. – Emory Bell Dec 21 '09 at 5:34

I had an old laptop that would occasionally report (false) very high temperature spikes - noticeable by the fan suddenly spinning up frantically, then switching off with the next temperature update, which was always back to normal. Once or twice the machine shut off because of this, but after a while it just stopped doing it, so not much help with trying to isolate your problem. – wrt Dec 21 '09 at 5:55
