Upgraded to Dualcore. Now megui reboots comp.

[junglemike]

I've been using Megui on my previous Celeron P4-1700mhz w/o any problems. I had it running for weeks non stop. I'm also using megui one couple of P3 computer w/o problem.
I've upgraded to Pentium D-915-2x2800mhz and now computer just reboots or gets stuck (screen is garbed ) - and I must reboot.

I don't use overclocking, I also tried to run cpu burn-in tests to verify stability and it passed OK.

What Should I do?
I've reinstalled megui many times. It happens somewhere from 20minutes after starting encoding to some hours.

if it's hard restting it can't be a userland process, it must be hardware/driver/kernel fault afaik. Monitor the temperature and see how it works. It's almostcertainly not megui btw, but rather the video encoder you are using (or the decoder).

I'm also thinking this way. do you know any software that can really maximally load Pentium D cpu? I've tested burn-in cpu test (which was designed for P3) on both cores. But maybe I need to test smth more?

I also tried to run cpu burn-in tests to verify stability and it passed OK.for how long and was it a test that maxes out your CPU (the prime tests are good at that). Also, RAM testing is paramount.. memory issues can explain a lot of random crashes.
I think I'd deserve a medal of megui could actually crash a machine.. managed code can't really access critical system resources (we do a little pointer arithmetic here and there but not in a way that could even even attempt to write to a position in the memory where you're not supposed to.. plus starting with WinXP SP2 it's really hard to write where you're not supposed to. It must therefore be something else.. if you run the encoder megui is running from the commandline, I'm convinced the exact same thing would happen - and since megui shows the commandline it uses in the logs, it's easy to do this experiment even if you have no experience running commandline apps.

Thank god you told me about memory. I thought memory is the last thing that can be responsible. I've downloaded memtest from this site (first found in google) http://hcidesign.com/memtest/purchase.html
and there are TONS of memory errors on this computer. I've tested my other computers which run megui w/o problem and they were fine.
Only thing i don't understand - how come other programs and windows don't crash since there hundreds of memory errors?

computers are weird like that. Another example is the TGMPEG MPEG2 encoder. It seems to be extremely sensitive to overclocking, on OCed computers that pass every other test they will bug out during TGMPEGs job.
