Random Reboot problem solving
I'm getting quite frustrated with random reboots. machine specs are:
Jetway J7F5 2.0 ghz c7
40gb Seagate 2.5" HDD
Windows XP home (legit and activated copy)
All hardware is new
the moboard, HDD and PS are mounted on a single plastic board. the moboard mount screws are grounded to wires that connect to car battery direct. both pos/neg wires to ps are direct connected to 2nd car battery through a fuse. jiggling doesn't reboot computer or cause power loss. the plastic mount board is screwed into vehicle body and solid.
I have also included 2 fans (1 in, 1 out) to cool the board, and system monitoring has HDD and CPU around 39-40c consistenly, so I've rulled out overheating.
The reboots don't seem to be tied to any one activity. They occur when car is running or not. Not associated with any one app.
Steps I've taken are a complete reformat and reinstall of XP, and still occuring. I've also (prior to reinstall) turned off windows restart on error, and have monitored the event logs. I also have Norton AV fully updated, and found nothing on a full sweep.
I've gotten several different BSOD (0x00000024, 0x0000008e, 0x00000050)
1) how do I determine which events in the log caused a fatal error. the amount of events, warnings and errors over nothing (ie multiple dcip due to lost wireless connections) are overwhelming.
2) what is a good methodological procedure to rule out issues and isolate the root cause? I don't have a floppy, so I have to figure out a way to test the memory on startup.
thanks in advance. dreaming of a stable system.
