Why does my laptop freeze in the middle of something

By mahmoodr46 ·
I have a Fujitsu Siemens Laptop with Vista Home premium OS and intel core duo processor (T2450- 2 GHz) and 2.5GB ram my problem is that my laptop just freezes in the middle of something either when surfing or trying to open an email ar any other file. The screen that I am on remains displayed but the computer does not respond to either mouse clicks or any other function keys the screen just remains frozen. I have to switch off and then turn it on again after some time and the windows option to start normally is displayed that I accept and computer reboots into windows. Can anyone help/ advise what could be the problem

Solid freeze? Do a memory test.

by dave In reply to Why does my laptop freeze ...

I suspect a memory issue here. Try Memtest86, or Goldmem offline testers.

Possibly the right answer

Your graphics chip is overheating.
This is common problem to many laptops and usually caused by the heatsink having gradualy changed shape so that it no longer sits pressed hard against the CPU/GPU.
Metal is like plasticene in slow motion and the heat sink metal flows around the cpu heat spreader( very rough analogy).
Every such freezing-up you experience, IF CAUSED by this , ( 90% certain) can be solved by crude and simple butchery.
Open said laptop and locate where the relevant chip is ( Intel graphics probably, so NOT the CPU itself) and unassemble the heat assembly( ie unscrew the heatsink thus exposing the heatspreader or the gooey blue cheap thermal gunge/cloth stuck atop the heatspreader.
If you can get hold of more of the same blue gunge/cloth just pack more of the same ( the more the better-within reason) and re-screw the heat sink back as tight as it was.
Basically you need to re-establish the same effective contact between the heat-plate and the heat-spreader as exsisted when the laptop stork delivered it to you.
While you are at it remove all fluff and dirt from your Cooling fans in the laptop as they will be contaminated by normal use.
Your laptop will work properly and for as long as you want it to.
This remedy is for those who are competant working inside a computer.
Laptops are made by ordinary people with two hands like you(and me).
If they can make it you can certainly maintain it.
They were not made by Octopusses(?).
But if you can afford it, send it off and be taken for a ride by many of the so called laptop experts.
They will overcharge you for what is usually a very simple remedy.
As a new Citizen of this Republic Of Technia I feel that it is my duty to encourage my fellow country-folk to have a go.
Please first work on a cheap old Pentium 3 laptop and gain some experience before attempting to work on your own current(and valuable) laptop.
You dont have to fix anything on the old lappie, but just learn dissemble and reassemble it so it continues to work normaly.
If it continues to work then you are doing a good enough job to progress to more worthy machines.
I apologise for the lenght of this reply and did not go into the symptoms of your problem as you have done this enough already.
It seems very like a graphical freeze up as the laptop doesnt overheat and shut down., it just goes solid while appearing to be healthy visualy and aurally( no whining fans).
Good luck.

Dumb question here...

by _Papa_ In reply to Why does my laptop freeze ...

Is 2.5 gigs a good figure for memory? I always thought it should be a whole integer.

Sounds like you have a 2GB chi[p and a 512MB chip. While it should work, there could be a slight performance degradation due to mismatch in the chips (could be different manufacturers or other mismatches). I remember back in the "old days", if you had 2 memory chips (same amount of memory), but different manufacturers, OSes like OS/2 and even some early versions of Windows would crash at times (if you could boot them). Todays OSes aren't as sensitive, but H/W still is and a mismatch can make the speed reduce to the slowest chip.

thanks you are right about the chips

Freezing or the direct opposite?

by gdburton In reply to Why does my laptop freeze ...

When things like lock-ups happen at random points, rather than consistently "when I try....", I always look for a hardware explanation. RAM problems is a possibility, but another is thermal problems. Try running "SpeedFan" to chart processor temps. If you are able to see the graph when the lock-up occurs you may see that temp has been increasing to a stupidly high level.

Many Vista era machines will have accumulated enough dust & fluff to totally block the cooling path. Quick easy fix if you are handy with service manual and screwdriver.
Just an idea!

You say that you 'got' the laptop recently.
I dont see how that can be possible that this is- as you describe it - a new laptop as the model came out at least three years ago.
Can you give more accurate story of where the laptop has been for the last two years?
If it is new then none of the answers you were given would be relevant.
If you are in financial services in the middle east I would have thought you could have afforded a much better laptop.
Is there something special about this cheap English laptop that you can share with us all? Lol!
I could also give you a more appropriate answer.

friend I did not say that it was a new machine but that the problem started a few weeks after I got it which was about three years or so ago.
