Prime95 keeps crashing...
 

On my notebook, Prime95 only manages to run for about 3-4 minutes before there is some catasrophic error that makes Windows shut the program down. It even happens in safe mode. If I launch the program again, Windows shuts it down again after 3-4 min. Is this a hardware failure? Or is this Windows not cooperating? I've tried reinstalling it, and uninstalling, rebooting, and installing it again, but I get the same error.

2.0 Pentium M (no overclocking)
512MB ram
80GB HDD
Windows XP Pro, SP2
Prime95, latest version off the site (24.14 I think?)

Thank you. :smile:

Try using the THROTTLE option as stated in the help documents. Intially try setting it to be the same as the time per iteration.

If this works it is likely a heat issue.

I still get the Windows error. :sad:

Have you tried [URL="http://www.memtest86.com/"]memtest86[/URL]?

Or [url=http://www.memtest.org/]Memtest86+[/url]? This one is based on the old memtest86 but with a much wider hardware recognition and support.

I just did memtest86+. The result after 2.5 hours was 10 passes and 0 errors. What else can I do? :ermm:

We don't know your notebook's model... :ermm:

It could be that the BIOS has a "shutdown if temperature execeeds X temperature" which could kick in when Prime95 is run... :unsure:

Another thing you could try is to get a non-Windows boot CD like UBCD (which has P95 as a test program -- recommended by me) or a live Linux CD such as Knoppix (which does not have P95 -- I think it can only read Micro$oft's NTFS and probably doesn't have a Windoze emulator.) Try [URL="http://www.ultimatebootcd.com/"]UBCD[/URL].

If it turns out to be a temperature problem, it may be symptomatic of a broken fan or blocked air ducts. You might even need a Laptop cooling pad...

You're tripping the heat sensor. There's nothing you can do but throttle Prime95.

I have a Dell Latitude D610.

I don't think it's a heat problem, as it only crashes shortly after the fan turns on, and it's only P95 that crashes, not Windows or anything else. I get a "P95 has encountered a problem and must shut down. You can report this problem to Microsoft" error. The program has worked before, it just started to act up only recently.

I throttled n=1000000000, and I still get the error after approx. 4 min of factoring.

Throttling only affects LL testing, not TF or p-1.

Maybe your cooling sytem is malfuntioning. See if you can clean out the airducts and processor fan with compressed air and/or vacuum cleaner. :glare:
