Cause that's the only resonable explanation for my computer's behavior. You know how with ATX form factors the power button is "software controlled' therefore you can define what it does, and when the PC freezes the only way to turn it off is to either hold the "software off button" on the front side for 4-sec, or use the REAL off button on the PSU. Anyways, sometimes my win 98 freezes on shut down (wow, surprise, ain't it). At such time I use the soft-off button and hold it for 4 seconds until the PC turns off. However for the last few months I noticed that when that procedure is done, my PC has a tendency to automatically turn back ON after a random amt of time. Like last night, windows froze, I used the soft off button, went to sleep, and an hour later I woke up to my PC's "beep." Usually it turns back on a lot sooner. Any idea what might be causing this? I supposedly turned off "automaticly turn on by keyboard, mouse, or at a specified time" in the BIOS, but I didn't see any such option for USB devices. I have my USB-Card reader and my USB web-cam plugged in, it was already doing it before the web-cam. Could the USB reader be somehow responsible for it?
Here's what's weird, when I turn the PC off normally, that is by pushing soft-off power button when the PC is NOT frozen, or is in Linux, or DOS, or whatever, the PC does NOT turn back on agaon.
