Fujitsu Siemens desktop freezes intermittently
Posted on 2006-03-30
I have a Fujitsu Siemens desktop that freezes every couple of days or so, the only way out is to cycle the power. There is no obvious trigger to the freeze when it happens, but sometimes it occurs when you walk up to the machine and move the mouse to start work. Then the picture flicks once and then the machine is completely locked up. I do not think this is the actual cause, more like the last straw once the systems starts to breakdown, as most of the time the machine works just fine...
I have configured the system to bugcheck when I press ctrl-prtscr twice. This works normally, but when the system is frozen, this does not work so the hang-up is pretty deep in the system. I have run the Windows Memory diagnostic and has not shown any memory errors.
The machine is under warranty and is covered for next business day site visit BUT the Fujutsu-Siemens help desk will not send anybody out until I have run the 18month old recover disk and blasted my XP SP2 software configuration with some old SP1 rubbish. As this outrageous demand is not likely to provide any useful diagnostic information, I do not want to do this until I have exhausted all other avenues!!!
The system is a Fujitsu Siemens Scenic P300 with a D1451 motherboard, configured with 768MB of RAM, running XP Pro SP2 with all the latest updates.
So I am assuming it is some sort of motherboard problem, but do not really know where to start to diagnose the problem.
1. how to unfreeze the system when it hangs?
2. to diganose why/where it is hanging?
3. to test the motherboard?
