Hi,

I have a delicate problem. I have installed suse 10.0 ( I used winME
before but got tired of all problems) on a FujitsuSiemes scaleo, 800
Mhz Celeron.
When I boot my linux box I can see what is going on ( boot sequence)
then my x-window is started and I get my GNOME environment. Then apps (
wireless network, mail ...) are loaded in the panel ( as they are
started). If I try to start e.g. mozilla or firefox browser then system
reboots. If i do that before icons in panel is loaded system also
reboots. :-(
If I let my system run for I while it seems like I can start browsers,
ide:s and so on without a reboot.
I never had these kind of problems in windows ( though others ......).
Is it something that is not warm enough in the beginning?
I have gotten suggestions on the following:

bad memory (RAM), video drivers, and a bad power supply.

I checked the ram with 'Mem Test' and it is fine.
I have no extra video drivers installed.

I am starting to begin it has something to do with the power supply
since everything is rather cold in the beginning ( when booting). And
also it is not likely that the CPU is overheating at this stage or?

All hints are welcome!

cheers,

1. swap your ram about , to different slots then run the memtest (test)5
(move blocks)

I had a real shitty problem, that just would not show up on memtest running
over night , but showed up every time on block moves, after 20 minutes

sometimes it is a timing issue , that memtest will not pick up, as it does
not emulate how a system actually runs., sequentially accessing memory can
actually hide some problems.


next thing to check , restart the machine and enter into the bios. go to the
section that monitors your PSU voltages, watch out for the 3.x voltage and
make sure it is dead stable , if possible do it with the case open, to force
the motherboard /cpu & psu to work harder on cooling.

finally , pop your pci/agp cards out, and check the connectors are clean ,
then re-seat the cards.
