ATX power problems! Please advise!!

[jfdid]

I have a P233 with ATX power. It was working fine, then I installed my modem and now it(the computer) won't shut off after I choose shut down from the start menu-it just reboots. When I plug my Zip drive in, the ATX works again!?! As soon as I take off my Zip it stops working. As soon as I take out my modem it starts working? Anyone know the problem/cure? Thanks

If you updated your Bios recently the problem could be with that. This was the cause for someone else. I guess here, the point is, not to update the bios if you don't need the features it adds.
Anyhow if you didn't, turn off all Power Management features in the Bios. Disable the RTC Wake-up feature also.
Diable Power Management in Windows Control Panel. Restart and the system should stop mis-behaving. Then, if you want you can turn on the power management features within windows. It's best to leave it off though.

thanks but it didn't work...Is my motherboard screwed up?
When I go to shut down, I see the
"Windows is shutting down" screen and then the
"It is now safe to..." for only a split second and my computer restarts?

Is the ZIP set as a bootable device in the BIOS? If so, make it non-bootable.

Have you tried removing both devices and all references, from within Windows (you aren't runnig NT?) and physically reinserting the modem in another slot (an internal one, right?). Setup the modem first then add the ZIP (IDE?) drive.

Are you running a network or are there any network protocals loading? If so, this is a symtom that can occure under certain conditions, however, this isn't the case right? On the remote chance it is, get rid (swicth from) of the offending protocal. The Novell client I think.

One other thing. LOok in the Autoexec for a line referencing Win.com /W or /WX. If it's there that will also cause the system to reboot. Delete the line.

Assuming the ZIP is an IDE, your not using NT and you did the things mentioned in the previous reply, I can't think of what else it might be but hardware or a BIOS update.

I tried these things but none worked...Oh well maybe I'll just have to live with it untill I get a new modem. Maybe I'll get ADSL? Any comments about ADSL vs. ISDN?
