if i leave the pc on it may shutdown and restart on its own after a couple hours of non use or several times in a row after a few minutes of non use.It does it everytime i try to write to the cdwriter from any other pc on the network.if i try to write to the cd from my pc sometimes it works and sometimes it doesnt.if i try to transfer files in either direction between it and another pc it will process about half a file and then reboot.
heres what ive done trying to fix it:
ive run various types of memmory 64mb,128mb,256mb,512mb(current)ive used pc100 and pc133(current) kingston,pny,and crucial (current)
ive used two different power suplies the one that came with the case..300watt and also tried a 400watt from comp usa. i put the old power supply(current) back in.
ive tried it with an ups installed and without the ups(current)...no difference.
ive checked and rechecked every card in the system including reseating the processor itself several times.
Asus probe shows nothing abnormal and cool as far as temperature.
Ive gone into bios and set power managment at dissabled user defined etc...Ive also gone into the windows power managment and set it to desktop and all the other settings never on the hard drive monitor etc...no change made any difference.Its set on never /never/disabled for now.
i get no error messages and no BSOD. its like someone walks up and hits the reset button.Ive watched it happen from across the room.scandisk runs and it goes all the way back to the desktop every time.I also have had no problems running any applications like MS Office, games, surfin the web etc other than what happens above....It seems to be random except for network activity.
Sysstem specs are: Asus P2B Asus tnt 16mb AGP video card Sis 8 mb pci video card 512 mb crucial pc133 inwin q500 case celeron 300 w/factory heatsink and fan ls 120 superdisk 5.25 floppy ? 3.5 floppy mitsumi digital research 40x cdrom hp 9110 cdrw ibm 5400 15gb hd wd 5400 17gb hd linkseys lan card creative awe 64 sound card creative flash2 56k v90 flex modem i case fan in at bottom 2 ball bearing fans from radio shack blowing on drives and mb i extra exhaust fan out at top of case.
Any Ideas?Something...i might have missed?Suggestions?
Wow, you have that system loaded to the gills. There is something that does not add up. You have two hard drives, two CD drives, two floppies, AND a LS120 superdisk. How?
The things I can think of: . 1) The power management on the motherboard is being overtaxed. Is there a way you can track all the voltages on the motherboard to make sure they are not dropping too low? Could you easily try to run it without one of the video cards and the sound card?
. 2) The CPU is being overloaded by some process. Do you have something like a 400 MHz Pentium II processor you can test it with? Have you looked at the available System Resources before this happens? Did you pare down your startup files?
. 3) Device conflict. Try moving around the ethernet card and maybe try a newer driver. Did you check to be sure there are no errors in the Hardware Profile?
. 4) Software conflict. What software are you using to allow other computers to access the CDRW over the LAN?

I dont remember which but either the LS120 or the cdrom is running off the soundcard IDE. i think its the cdrom.

I tried watching the voltage readings with the asus probe but it reboots too fast to see anything. . 2) The CPU is being overloaded by some process. Do you have something like a 400 MHz Pentium II processor you can test it with?
was thinking about upgrading to 1.0ghz.I may have to try that, but really would like to know its not a mb problem first. Have you looked at the available System Resources before this happens? Did you pare down your startup files?
will have to look at both of these.

It's been running this way for a couple of years.The problem started suddenly with no changes to OS or hardware. . 4) Software conflict. What software are you using to allow other computers to access the CDRW over the LAN?
normally i transfer all the files to a folder designated on one of my partitions called burntemp.once there i just use the cdrw to write the disk.I cant seem to do that from either end now without causing a reboot.Before this problem started was able to use the hp cdrw software and browse to her computer that is shared and select the files to write to cd.For some reason doing that causes a reboot now.
im leaning towards a bad processor..what do you think?
a guy had a modem that was set to turn on when ever someone called his line, so when the phoen would ring his computer would turn on.................so try checking stuff with the modem......
That's the track I'm thinking, software conflict. Ctrl/alt/del all background apps, disconnect all external devices, see if it still happens. Add them back in one at a time if it fixes it.
