Random 2 tone beeps - second try
Hi folks,
This is my second attempt at asking this. No responses of yet. Puzzling stuff. Here's the original post: ********************************** We have a PC that starts emmitting 2 tone beeps and sometime single tone beeps _AFTER_ post and during normal Windoze operation. After searching the Google archives, it seems that this could be caused by the mobo notifying temperature problems or a wacky keyboard. I can positively attest that none of these symptoms are occuring on this machine. I unplugged the keyboard. Still beeps. The BIOS reports CPU temp at 37 deg. C. and fans are normal. It's relatively cool in there. Just to make sure, I removed the cover from the pc, shut it down for an hour and booted up again. As soon as post was done, the beeps started again. The beeps occur very randomly. In the end, I simply disconnected the speaker. Not the best action to take, but the person who uses this PC needs to have a very quiet room since it's a very specialized Q&A dept. and the operator is going insane with all those beeps g. This PC is running Windoze 98 SE and I haven't collected any hardware specs as of now. ********************************** Since then, the PC started rebooting by itself numerous times a day. So I changed the 250W power supply for a brand new 300W one. Still beeps and waiting to see if it will reboot itslef. Again, the temp is ok. Weird huh ? Thanks Steph |

Dave,
The mobo is a Microstar 6163 http://www.msi.com.tw/program/produc...il.php?UID=114 After replacing the PS, the machine started rebooting by itself again, so that wasn't it. I also replaced ram, but still beeps and still reboots. Note that it will only reboot if I put a good memory load on it, like opening many apps or just one big mem intensive app. I tried Defrag just as a test, but it didn't reboot using that so the HD probably isn't causing this. I'm at a loss. Steph "kony" wrote in message ... On Fri, 24 Oct 2003 09:20:19 -0400, "Stephane Hebert" wrote: Hi folks, This is my second attempt at asking this. No responses of yet. Puzzling stuff.

Ooops ! Wrong mobo.

I see that happening a lot with them running hot and too little airflow. The only realistic solution is replacing the motherboard, unless you're practiced in replacing capcacitors, as it isn't cost-effective to have a shop do it. Dave |

I know that the temp is ok cause I don't cry out in pain when I stick my tongue between the CPU and the heatsink Actually, I used a probe and temp was 37C. Still the beeps are a total mystery to me. We're replacing the mobo this morning. Thanks Steph "Phrederick" wrote in message newsnhmb.168403$6C4.68269@pd7tw1no...

Turns out the mobo was the problem. I can't find any docs on what those
beeps are. Very bizarre. Thanks to all who tried. Steph "Phrederick" wrote in message newsnhmb.168403$6C4.68269@pd7tw1no...
