24.14 Crashing windows - only with some options

markg · 2008-04-27, 06:21

i have been running 24.14 on a laptop for a few months with no troubles.

it was set up to do primality tests only, but its slow (apparently) and i figured after this one finished it would be better to run factoring. so i went to "type of work to request from server" , unchecked primality and checked factoring.

even though it wasnt finished with the primality test, it got a couple factoring jobs, and promptly began crashing with the windows window (send error report etc.).

whats up with this? any suggestions? its about halfway through a primality test, and i dont want to lose the work.

thanks,

mark

Try to use Tweak UI or Process Explorer to view running processes

Most likely the laptop has got dusty. Vacuum the vents.

If you do not have sufficient RAM for factoring, it is possible the disk is being used for extra memory and is causing too much extra heat.

I agree.

First of all it is almost certain the machine is first finishing the current LL test. Secondly Trial factoring uses les memory than LL testing. So heat produced by memory swapping to disk is most certainly not the cause of the crashing.

when i open the prime95 window, it says it is factoring....

everything else is fine; i will try cleaning it out etc., but it crashes right away, even when turned off for a while (so not apparently heat related)

i had it set up for using 256mb ram day/night; i figured that was enough

Download and run memtest86+. If you download the CD version, use your burning sofware's ISO option.

You will need to boot memtest instead of Windows -- there should be a special key -- maybe [F11] or [Esc]-- that you press when the laptop is switched on to allow you to select the boot media.

It still could be dust even after a cursory clean, if the CPU heatsink and fan are clogged up. Prime95 will max out your CPU and that means extra heat, which could be enough to cause a crash.

no issue with memory; but it ONLY crashes prime95, nothing else. still does. right away after booting, within a minute or two.

Did you run metest86+?

Do you run XP? Is it fully patched up?

Do you have all malware protection software patched up? Have you scanned with these?

What is you laptop make and model? In its BIOS, what are the temperature and voltage readings?

memteset 86+ yes; ran it for a day, no issue
xp is fully patched
scanned fine multiple times, both installed and on line scanners
laptop is ibmt40p. it worked for MONTHS, and still works fine.

when i reinstalled prime95, it worked fine as well.

then i copied over the prior config files, and it started crashing again.

This one for a GIMPSter. My hunch is: something is wrong with the worktodo file or a config file or, possibly, the save file (or all.) Can you try to eliminate which? Copy them one at a time to a fresh install and test until the error occurs. HTH
