LG 4120B DVD WRiter/CPU Fan shutdown

[Guest]

I am hoping someone can help me. I built a computer a couple of weeks ago. I
got everything going good until one day my system overheated and shutdown.
Everything was running well and then all of a sudden my CPU fan shutdown.
Obviously this scared me even though it did not happen again until today. I
had unhooked my DVD writer(LG DVD REwriter 4120B) because my system was
crashing (complete automatic shutdown crashes) at weird times and my computer
stopped recognizing my Rewriter as anything but a cd-rom. When I disabled the
drive my computer seemed pretty happy (no more crashing). I was still trying
to troubleshoot why my pc overheated so I decided to hook up my Lg DVD writer
again. The first time I turned my computer on after connecting the IDE cable
and the power to my dvd writer the CPU warn came on and the fan shut it self
off. I immediatly shutdown and restarted the machine. Same thing. I unhooked
the drive again and the computer alarm came on and the fan stopped until
windows loaded up and then it started and the alarm stopped. I tried this
process a few time with the same results. I have since put a cd-rom in the
same slot and hooked up the same cables and everything seems okay. Very
weird. I have emailed LG tech support but I thought that I would throw this
out there and see if anybody had suggestions. I am really concerned about
permanent damage to my system. Spec if this help. K8NS Pro Gigabyte
motherboard, AMD Athalon 64 3000+ with 512 ddr Ram and running ATI 9700OW
Pro. If anyone's got anythng I would love to hear it.

Thanks

Check to see if the power supply is large enough to handle the hardware.
Then check the temperature the CPU is running when it shuts down. May be the
heat sink is not completely seatd on the CPU or it is too small to properly
cool it, then again the fan warning temp may be set too low.
